Best Practices and Guidelines
The best practices and design guidelines are tools to assist the designers and users in realising universal accessibility. The guidelines are an extension of the design considerations in Section 5. Best practices and examples are illustrated for each subject. The intention is not to cover every aspect of design details on a particular subject. The designer should refer to relevant Ordinances, Design Manuals and Standards for compliance with statutory and other requirements.
The best practices highlight generic issues and list the major areas for continual improvement on universal accessibility. Best practices, practical solutions and options to achieve the objectives for future projects and facilities are documented. Designer for specific project can always design for a more accessible environment with reference to the guidelines.
Universal Accessibility – Best Practices and Guidelines
Architectural Services Department
6.1 Access Strategy 6.1.1 Planning for access
6.1 Access Strategy 6.1.1 Planning for access Access planning (6.1.1a) for public buildings and community facilities offers great opportunities to design for everybody. It requires sensitivity to create an accessible environment. It is not just a regulatory requirement since more than the minimum would be required to achieve the target.
to information. The process involves collaboration with users, operators as well as co-ordination with government departments. Major access issues (6.1.1b) include the following:• Access from transportation and on foot. • Access to information and way finding. • Access to entrance, all levels and functions. • Access to equipment and service.
The process is an ongoing one involving many parties to create an accessible built environment by addressing various designs and operating issues. During the concept planning, it is a good chance to collaborate with the stakeholders to promote and facilitate integration of 'Universal Design'and provide innovative and good design solutions.
A strategy should be developed to cover the complete travel chain, from traffic drop off point to initial approach; to all parts of the building; to services and

6.1.1b) Planning access
Universal Accessibility – Best Practices and Guidelines
6.1.2 Planning access to historical buildings
6.1.2a) Preserve old facade
6.1.2 Planning access to historical buildings Historical buildings (6.1.2a) present unique challenge and limitations, yet access solutions in meeting the legal and functional requirements must be considered. Certain alteration and additions are required to bring the historical building in line with contemporary requirements although minimum intervention principal to the historical structure and building fabric should be observed.
The possible future of the monument, the use of the building and the anticipated users are critical factors in formulating the access strategy. For example, the access solutions for a museum will be quite different to that of the Court of Final Appeal. Easy access would increase visitation to the museum and open up the market whereas security requirements may be the overriding factor which will only permit limited access to the Court.
In addition to the general approach to develop an access strategy outlined in 6.1.1 above, an audit (6.1.2b) is necessary to identify elements of significance that must be conserved and determine accessibility requirements (6.1.2c). If the audit identifies certain elements that are unique and structural alterations are difficult, options for access would be to identify an initial access point, convert an existing window into access doorway, and/or utilise the open courtyard for installation of a new lift. The access point for the disabled should be accorded with due respects and should never be a back ally or back door.
In addition to the requirements arising from the functional use of the building, the requirements of the Authority under the Antiquities and Monuments Ordinance (AMO) are also prime considerations. The additional check list items for historical buildings are:• Conduct building survey. • Identify significant conservation elements. • Identify existing and required access. • Consider and evaluate access options in the context of AMO.
6.1.2b) Work out elements to be preserved and access requirements
Universal Accessibility – Best Practices and Guidelines
6.1.2c) Provide a ramp access to the building
Architectural Services Department
6.1.3 Access plan
6.1.3 Access plan It takes a conscious effort to identify various accessible routes (6.1.3a) and ensure accessibility for different user groups. This includes the elderly, the visually impaired, the ambulant and wheelchair users, the speech and hearing impaired, as well as the fit and abled. The access plan can be developed into a diagrammatic access layout. This lay down the functional requirements for detail planning and can be used as an access guide. The access guide can provide information for the public at airport, border check points, tourist attraction and internet web sites to reach the facility. Relevant standards and legislation such as the Transport Planning & Design Manual issued by Transport Department and the Design Manual Barrier Free Access issued by Buildings Department provides the statutory requirements.
Develop an access layout: a. From MTR Station to lift no. 1 and go up to the concourse. b. Travel along the accessible route and take lift no. 3 to go up to the elevated walkway. c. Come out of the lift and go to the "BUILDING". Consider way finding along accessible route: a. Consider locations for signage, tactile map, talking sign at MTR station, cross roads and facility entrance. b. Consider detail of information for way finding e.g. district map, street name, building name, lift, staircase and car park location.
6.1.3a) Identify various accessible routes
Architectural Services Department
Universal Accessibility – Best Practices and Guidelines
6.1.3 Access plan
Successful implementation of the access plan requires attention to detail during design, construction and maintenance. The following are important items to consider:• Identify accessible route from public transport, surrounding streets and link bridges. • Identify safe access and entry level from pedestrian path, elevated walkways and car park area. • Consider access options to facilitate independent access. • Consider access to all levels in a building and/or open space to facilitate a continuous accessible path. • Consider building/facility and service layout options to facilitate unimpeded access and flexibility in use. • Consider information, way finding (6.1.3b) at public transport station and street access entry points to major facilities. • Consider directory signage, information counters and other public facilities such as telephone booth at principal entry points to facilities.
• Evaluate access and evacuation options including consultation with users/operators and relevant authorities. • Prepare access plan including access requirements and management arrangements.
6.1.3b) Provide way finding clues

Architectural Services Department
6.1.4 Evacuation plan
The current legislation in Hong Kong stipulates access requirements for the disabled. However, means of escape (MOE) for the disabled is also an area of concern as certain user groups are dependent on assisted escape. In addition, management arrangements are required to provide assisted escape for some disabled groups. Special arrangements are required for the ambulant and elderly people as well. Options of assisted escape include:• Fire separating measures to contain the fire e.g. fire shutters. • Refuge area to enable people to wait for rescue e.g. provision of a refuge room next to fireman's lift lobby (6.1.4a). • Phased evac uation for the people most affected. • Evacuation by fireman's lift under supervision. • Evacuation by stairs with assisted device such as canvas bed or Evac chair.
6.1.4a) Consider options of assisted escape
Architectural Services Department
The above list is not exhaustive and MOE for the disabled should be considered with the stakeholders in developing the evacuation plan. It requires awareness, risk assessment, management commitment and training. In working out the details of the evacuation plan, considerations on emergency communication system, sound and visual alert system, security system and storage for assisted devices should be considered. Floor mounted exit signs (6.1.4b) and low level exit signs (6.1.4c) along escape routes can assist and guide both the able and the disabled to exit staircase. Consideration should be given to provide and display a plan in a conspicuous location showing fire escape routing with colour coding indicating MOE for the disabled.
6.1.4b) Consider floor mounted exit sign
Universal Accessibility – Best Practices and Guidelines
6.1.4c) Consider low level fire exit sign
6.2 Walkways and Ramps 6.2.1 Accessible walking surface 6.2.2 Walkways
6.2 Walkways and Ramps 6.2.1 Accessible walking surface Persons with special needs or with a disability shall have the same freedom of movement as ordinary persons within a building or at external area (6.2.1a). Access should be made available for all people to approach, enter or leave a building and to use the facilities independently. A walkway with a gradient not steeper than 1 in 20 or a ramp of gradient not steeper than 1 in 12 would form an accessible route. 6.2.2 Walkways Width of walkways shall not be less than 1050mm clear. Best practice is to provide 1200mm wide walkway to enable a wheelchair to turn, and preferably 1500mm to allow two wheelchairs to pass (6.2.2a).
stream or water feature. Walkways should be clear of obstruction (6.2.2b). Special consideration is required to recess or eliminate such obstacles when walkways cross over spaces with low headroom such as spaces under escalators and staircases, or when fittings projecting more than 90mm beyond the wall surfaces and below 2000mm high are found along the walkway. A covered walkway or ramp is recommended where access is provided between platforms or facilities at different levels. A covered walkway (6.2.2c) should be provided linking two buildings where frequent access between the buildings is required.
Safety measures in the form of buffer planters, railings, safety barriers or warnings should be provided if a walkway passes through any pool,

6.2.2 Walkways 6.2.3 Ramps
Surface and level changes • Walkway surfaces should be stable, firm and should lie generally in a continuous plane with a minimum of surface warping. • The cross slope of walkways should not exceed 1:50 except pavement on streets with the natural topography exceeding 1:20. • Walkways should have continuous common surfaces and not interrupted by steps or changes in level greater than 6mm. • Thresholds should not exceed 25mm in height and should be bevelled to facilitate smooth passage of wheels. • The intersecting surface where a walkway crosses or joins streets, public footpaths, driveways or parking area should blend into a common level with slope no greater than 1:20, or a dropped kerb should be provided. Drainage • Fall and drainage shall be designed to minimize water ponding or flow of water across walkways. • Channel cover gratings located in walkways should be designed with spaces less than 13mm (6.2.2d). Holes in channel covers should not be grater than 20mm. Refer to Section 6.4.2 for other considerations on channel cover gratings. • Covers to a channel shall be flushed with the surface of the walkway. • Outdoor walkways, ramps and their approach should be designed so that water will not accumulate on walking surfaces. • Structural fall should be considered for effective rainwater discharge.
6.2.2d) An accessible route
Architectural Services Department
Braille and tactile guide • Provide tactile guide path from the walkway entry point to lift zones, and functional areas such as reception counters. • Locations of Braille and tactile layout plan and the main means of vertical circulation (i.e. lifts, staircases and escalators) should be provided. 6.2.3 Ramps Ramps are sloping walkways and should have the least possible gradient. It is desirable to have more gentle slopes and slopes are recommended to reduce to a gradient of 1 in 20 if possible. The maximum gradient of a ramp shall be 1:12 measured between any two points on the ramp. The minimum clear width of a ramp shall be 1050mm. Similar to walkways, width of a ramp should be at least 1200mm for a wheelchair to turn (6.2.3a) or at least 1500mm for 2 wheelchairs to pass. Handrails shall be provided on both sides of a ramp. Refer to Section 6.5 for handrail requirement.
6.2.3a) Provide ramp with handrail and level landing
Universal Accessibility – Best Practices and Guidelines
6.2.3 Ramps
Gradient, rise and landing • The recommended maximum rise for any run is 800mm. • Landings for turning and resting should be provided. A minimum landing of 1500mm by 1500mm shall be located at the bottom and the top of each ramp. A landing of width and length not less than the width of the ramp should be provided when the ramp changes direction. The maximum length of a ramp run between landings shall not exceed 10m length of horizontal run or part thereof, and the landing should not be less than 1200mm long. • Circular ramps are not recommended especially those with small turning radii, which would render wheelchairs difficult to manoeuvre. • The cross slope of ramp surface should not be greater than 1:50. • Landings shall be level and unobstructed by projections and door swings. • If a ramp with a rise greater than 200mm leads down towards an area with vehicular traffic, a railing or barrier across the full width of its lower end, not less than 1500mm from the foot of the ramp should be provided for safety purpose.
Surfaces • Ramp surfaces shall be stable, firm, and slip resistant (6.2.3b). • Provide tactile warning strips at the head and foot of a ramp and at intermediate landings. • Use contrasting colours for floor and wall along ramps. • Similar to walkways, ramps should be clear of obstruction (6.2.3c). If unavoidable, they shall be extended downwards to the ramp level or be guided by tactile flooring materials. • Outdoor pedestrian ramps should be provided with adequate drainage gullies at each side of the ramp to drain away excessive surface water running down the ramp. Edge protection • Ramps and landings with drop-offs should have edge kerb, railings, or projecting surfaces to prevent people from slipping off the ramp. • Edge kerbs should have a minimum height of 100mm. For difference of adjacent levels greater than 600mm, lowermost solid protective edge should be 150mm high.

6.3 Car Parking 6.3.1 Linking places 6.3.2 Accessible car parking
6.3 Car Parking 6.3.1 Linking places The availability of public transport, provision of car parking spaces and lay bys greatly improves the mobility (6.3.1a) and participation opportunities of the elderly, people with disabilities and adults with young children in our community.
6.3.2 Accessible car parking Accessible car parking (6.3.2a) means that sufficient space is provided next to the vehicle so that the wheelchair users and people requiring assisted devices can transfer and manoeuvre to and from the vehicle on level ground. The following items require attention:-
Covered passenger drop-off area, taxi and Rehabus lay-bys, as well as parking areas should be considered for community facilities in general, especially for those venues attracting international visitors. Accessibility and connectivity should be amongst the major considerations in planning our built environment.
• The accessible car parking space should be on level ground and gradient of accessible parking area should not exceed 1 in 40. • Locate designated parking bays (6.3.2b) for the persons with a disability close to the main building entry or lift lobby linking to the main entrance and upper floors. • Provide safe passenger drop-off area for the elderly and people with disabilities near the main entrance if the parking space cannot be located close to the entrance or lift lobby. • Provide safe accessible path to the building entry i.e. the main front door or the entry to the building used by most people.
Designers should also refer to statutory requirements and guidelines relating to the provision of designated car park for the disabled and street parking in the Transport Planning & Design Manual issued by Transport Department and the Design Manual Barrier Free Access issued by Buildings Department.

Architectural Services Department
6.3.4 Multi-storey car parking 6.3.5 Special vehicle parking
6.3.4 Multi-storey car parking In planning multi-storey car parks, the general requirements for accessible car parking and accessible route should be compiled with. In addition, the following items require attention:• Consider provision of accessible car parking spaces at each level of the multi-storey car park. • Post directory sign (6.3.4a) on each level of car park to indicate location of designated car park space. • Provide ramps or wheelchair accessible lift linking different car parking levels for safe access. • Provide simple and easily operated car park entry and pay equipment that can be easily approached by the driver. Systems that are restrictive and reply only on intercoms should be avoided. • Post parking information (6.3.4b) and payment terms at entrance to a car park. If the pay arrangement involves paying at another location, suitable signage and direction should be posted. • Provide suitable headroom for commonly used vehicles for a covered car park space and consider requirements for Rehabus and coaches.
6.3.5 Special vehicle parking For facilities such as medical health care centres, elderly homes, rehabilitation centres and day care centers that require frequent service of special vehicles like Rehabus and ambulance, special consideration and designation of loading area (6.3.5a) and parking bays for these vehicles are required. The designated space should be on level ground and close to the lift lobby, under cover (6.3.5b), with suitable headroom and manoeuvring space. The parking bay for the ambulance should allow for back access of wheelchairs and beds onto the ambulance.

External circulation, landscaped areas and outdoor furniture 6.4.1 Entrance 6.4.2 Gratings 6.4.3 Landscaped Areas
External circulation, landscaped areas and outdoor furniture 6.4.1 Entrance External circulation leading to a building and the external landscaped areas form an important link in the travel chain. Best practices for the external areas are as follows. The approach to an accessible entrance should be a paved walk or ramp with a slip resistant surface, uninterrupted by steps. External circulation leading to entrance(s) (6.4.1a) shall have a level space on the interior and exterior of the entrance. Complete fencing off the entrance with bollards of narrow spacing at the entrances should be avoided. Consider and provide accessible entrance (6.4.1b) for all users to access the facilities independently.
6.4.2 Gratings If gratings are located on walking surfaces, the size of the openings shall be as small as possible to avoid trapping wheelchairs (6.4.2a) or sticks. Spaces between gratings should not be greater than 13mm wide in one direction. Elongated openings in gratings shall be placed so that the long dimension is perpendicular to the dominant direction of travel. The gratings should be of appropriate material and securely fixed to avoid removal; otherwise, the uncovered drainage channel (6.4.2b) will form a difficult barrier. 6.4.3 Landscaped Areas Design entrances to landscaped areas to be used by all users including the disabled, the aged and children.

Architectural Services Department
6.4.3 Landscaped Areas
All users shall enjoy the same route of travel (6.4.3a) as far as possible and have equal opportunity to explore and experience all features at their own pace. The landscaped area should be sized appropriately or subdivided into 'gardens'. The path through the garden should not be long and require too much effort to traverse.
Paths should be stable, smooth, firm, slip resistant and anti-skid. Joints should be tight and flush. The paths should be of appropriate gradient and sufficient width. Levelled alcove spaces should be provided at reasonable intervals as resting area. Where possible and practicable, the path for the visually impaired should be differentiated from the physically handicapped; as the tactile path for the former could be an inconvenience for the latter.
The scent and colours of planting (6.4.3b), sounds of water and wind features should offer a rich experience to users. Different elements such as water (6.4.3c), tactile and sculpture (6.4.3d) should be used to provide a sensory experience to the users.
section 6.2 on Walkways and Ramps)
Paths: A network of unobstructed paths should connect directly with all entrances, exits and main activity centres, as well as going around and through pieces of site furniture and equipment.
Way finding: Way-finding cues (6.4.3e) and signage should be sufficient and readily apparent; these include relief tiles, Braille text at the entrance and at each display, audio systems and text (in different languages) to
Users should be informed of their location in the garden, e.g. by landmarks, features or different surface materials along the walk and paths. (See also

provide a variety of methods from which a user may choose to receive information.
Different textures can also provide clues as to different areas of the playground.
(See also section 6.8 –Way finding and Signage)
Water features, such as paddling pools, waterfalls, streams and channels should allow the disabled and children to get close safely. Garden furniture and elements should be sized and positioned to accommodate multiple users simultaneously. Users, both standing and seated (6.4.3f), as well as people of short stature should be able to reach all components comfortably. (See also section 6.4.6 on Outdoor Furniture)
6.4.4 Playgrounds and Exercise Area Paving Paving in playing areas can be in different colours, for example, use different colours of impact absorbing surfacing materials (6.4.4a) to indicate different functions, different areas and changes in level.
Provide different play components in order to offer opportunities for children with various abilities to play together, encourage independence and offer a wide range of experiences and challenges. Provide seats and shelters at reasonable intervals to give opportunities for opting out of activities. Adequate covered seating with back rest and arm rest should be considered for users and their companions or carers at appropriate locations for supervision. Design features in playgrounds and exercise areas to stimulate the use and development of all the senses. Communication can be through more than visual cues, for example, touch (6.4.4b) and sounds can be used. The foot massage trail is also a good option (6.4.4c).
6.4.3f) Raised water bed to allow close contact with water for the wheelchair users

Where tunnels and bridges are provided, they should be sturdy enough and wide enough to accommodate wheelchair users. Tunnels with sequences of solid walls, window openings and exit/entry places reflect sound differently and can give clues to location, so long as materials that echo are used.
6.4.5 Water Sports Facilities Swimming pools, lap pools, wading pools, diving pools used for scuba or general swimming, and whirlpools and Jacuzzis shall be accessible. Accessibility to water facilities should be by means of any of the following:
Appropriate transfer platform should be provided to allow children of different abilities to access different • A sufficiently wide ramp with a slip resistant surface levels of modular play equipment. Adequate handrails extending into the shallow end of the pool. Such ramps shall have a slope not exceeding 1:6 (6.4.5a). and grab rails should be considered. Best practices are to provide a ramp 1200mm If a prime access to the equipment is the only route, wide with handrails on both sides and with a slope adequate space for transfer and manoeuvring for of 1:8. wheelchair users and their carers should be provided. • A lifting device such as a disable chair lift (6.4.5b). Platforms, resting places and places to turn around should be provided.

6.4.6 Outdoor Furniture
6.4.6 Outdoor Furniture Outdoor furniture and features such as lighting pole, bollards, seating benches and freestanding signposts must be positioned to allow for unobstructed access routes. Use colour or colour bands to make street furniture distinguishable from the background of the route. Free standing objects mounted on posts should not overhang for more than 300mm and below 2000mm from ground level. Provide protection to warn users, especially small children, the elderly and visually impaired if the headroom is reduced (6.4.6a) along the route.
6 Where obstructions or outdoor furniture within a walking zone cannot be avoided, use a paved textured surface around the unavoidable obstacle
6.4.6a) Potted plants put under the stairs as a remedial method X Should be avoided in new design
6.4.6b) Locate lighting pole outside accessible route
Universal Accessibility – Best Practices and Guidelines
from the line of walk. It should be placed 1000mm in front of the obstruction and extending 300mm to the side. Tree grilles to a width of 1000mm can be used around trees. An obstacle-free route of minimum 1800mm in width should be retained. As a remedial measure, a colour band of 150mm deep, with its bottom edge 1500mm above ground level could be incorporated to any posts or columns or other obstructions within a route. The band should contrast in colour and luminance with remainder of the post or column. Lighting posts: Locate lighting pole (6.4.6b) outside the accessible route. If it is unavoidable that lighting poles have to be located within the accessible route, use a contrasting colour finish to the base of the pole up to 1500mm high or provide a colour band at about 1500mm above ground level.
6.4.6c) Provide reflector to bollards
Architectural Services Department
6.4.6 Outdoor Furniture
Bollards: Low-level bollards and chain-linked posts are hazardous. If bollards are to be used, they should be at least 1000mm high and should not be linked with chains. A colour and luminance contrast feature (6.4.6c) should be provided to bollards. Bench seats: Provide seating at regular intervals (6.4.6d) along accessible routes. They should be readily accessible to all users but do not obstruct access routes. Allow a minimum 2000mm in width if the benches are not set back from the access route. Seats at different heights should be considered for children's facilities. The seat level should be generally 430-485mm above ground.
• Provide a firm wheelchair parking area 900mm wide on both sides of seating. • Seats should be provided with a back support and arm rests on both sides of the sitting position. The back support should extend to a point 450mm minimum above the seat (6.4.6e). • Use materials which do not significantly retain heat or cold. • The surface of benches installed in areas exposed to weather should be slip-resistant and should not accumulate water. Litter bins: Litter bins (6.4.6f) should be of big opening for easy dropping of litter by one hand.
They should be located in safe and well lit areas. Allow an area of 400mm in front of the seat. A tactile warning surface could be used when they form an obstruction. The following requires attention:-

Internal circulation, doorways and handrails 6.5.1 Accessible route
Internal circulation, doorways and handrails 6.5.1 Accessible route Following the principle of Equitable use, it is necessary to provide at least one accessible route to connect accessible building or facility entrances, all accessible elements and spaces that are on the same site and within the building. The accessible route shall, to the maximum extent feasible, coincide with the route for the general public. Colour and luminance contrast between walls and ceilings, and between walls and floors should be considered. Provide a passing space of approximately 1500mm by 1500mm at reasonable intervals if an accessible route has less than 1500mm clear width. A Tintersection of two corridors or walks is an acceptable passing place.
Provide unobstructed turning space (of minimum 2000mm diameter) at corners and unobstructed space for approaching and opening doors. Walks, corridors, passageways, aisles, or other circulation spaces shall have 2000mm minimum clear headroom (6.5.1a and 6.5.1b). If vertical clearance of an area adjoining an accessible route is less than 2000mm, a safety barrier of minimum 600mm high should be provided to warn the users, especially the visually impaired persons. Any protruding objects from the side wall should not obstruct people walking along the passageway. A space to provide for umbrella stack and 'parking' of wheelchairs (6.5.1c) should be considered, especially in public facilities like exhibition halls and museums so that those with walking difficulty can use a wheelchair inside the building.
6.5.1a) Planting placed to underside of an escalator with low headroom

6.5.2 Doorways
6.5.2 Doorways Lobby doors should be positioned for easy, unobstructed approach and passage (6.5.2a), and should ideally be automatic sliding doors. When a door into a lobby is open, there should be a minimum turning circle of 1500 by 1500mm remaining within the lobby. This requirement shall be required particularly in fixed-seating venues. Minimum manoeuvring clearances at doors that are not automatic or power-assisted shall be provided. The floor or ground area within the required clearances shall be level and clear. Revolving doors should not be the only means of access. The minimum space between two hinged or pivoted doors in series shall be 1200 mm plus the width of any door swinging into the space. Doors in series should swing either in the same direction or away from the space between the doors (6.5.2b).
6.5.2a) Easy approach to entrance
6.5.2b) Arrangement and minimum space to be provided in lobbies or vestibules

Universal Accessibility – Best Practices and Guidelines
Entry systems must not rely only on audible intercoms and must incorporate inclusive entry procedures. New technologies and improved designs for providing accessible entry systems should be considered. Entry systems for doors, gates and barriers should be designed to be accessible, located horizontally at 900mm above floor level and, where possible, should incorporate additional vertical systems. All numbers and letters on entry systems should be identifiable by raised symbols. The depth of embossing should be at least 1.5mm. Thresholds are preferably visible, for instance, with contrasting colour. If doorways have two independently operated door leaves, then at least one leaf shall meet the width of a single leaf door and that leaf shall be an active leaf.
6.5.2 Doorways
Doors and hardwares: Sliding doors should be power-operated where possible. Sliding automatic doors with no guard rails are more convenient for wheelchair users and visually impaired people. If an automatic door is used, then it should be opening and closing slowly and low-powered. Automatic doors shall not open to back check faster than 3 seconds and should require less than 66.6N to stop door movement. If a power-assisted door is used, its dooropening force should be minimum and not exceeding 22N. A vision panel of minimum width 150mm should be fitted to all doors to provide a viewing area, except where privacy is needed (for example, toilets, changing rooms or counselling rooms). The base of the vision panel should preferably be no higher than 500mm above floor level, and should extend to a minimum height of 1500mm (6.5.2c).
Fully glazed doors should be highlighted with conspicuous permanent contrasting strips or continuous features. The leading edge of the door should be with colour and luminance contrast. Handles, pulls, latches, locks, and other operating devices on accessible doors shall have a shape that is easy to grasp with one hand and does not require tight grasping, tight pinching, or twisting of the wrist to operate (6.5.2d). Lever-operated mechanisms, push-type mechanisms, and U-shaped handles are acceptable designs. When sliding doors are fully open, operating hardware shall be exposed and usable from both sides (6.5.2e). If a door has a closer, then the sweep period of the closer shall be adjusted so that from an open position of 70 degrees, the door will take at least 3 seconds to move to a point 75mm from the latch, measured to the leading edge of the door.
Beading around the vision panel should be flush with the door.

6.5.3 Handrails
6.5.3 Handrails Handrails should be provided to all ramps, staircases and steps. They can also be used alongside with a tactile guide path, along corridors, as protective barriers and guard against hazards, and can be a directional guide to doorways or positions of signage. Where continuous handrail is necessary, for example, in elderly residence, or handrail is used as a means for way-finding by the visually impaired, the arrangement at openings such as doorways, service ducts, hose reels (6.5.3a) should be carefully considered to avoid conflict or breaking of the handrail. The following items require attention: • The entire component should be securely fixed to the building structure and conveniently located so they can provide secure hand grip for persons to take their entire weight when required. Handrails should not rotate within their fittings. • Railing designs that allow children to climb must be avoided.
6.5.3a) Arrangement of continuous handrail with services layout

• Heights of handrails are preferably to be provided in pairs for adults and children, one at a height between 850 - 950mm and a lower one at a height between 450 – 500mm, measured vertically from the surface of the ramp or finished floor level to top of handrail. • Handrails shall be continuous without interruption, except at doorways and openings (6.5.3b and 6.5.3c), and with recessed brackets so that a hand can move from end to end without interruption. • The gripping surface shall be free of any sharp or abrasive elements. • The handrail material should be consistent throughout the entire length to avoid sending false messages to visually impaired persons due to change of material. • Handrails may be located in a wall recess if the recess is of a maximum depth of 75mm and extends at least 450mm above the top of the rail. • Handrails should be installed to resist a load of not less than 1.3kN applied vertically or horizontally.
6.5.3c) A removable handrail where openings are required
6.6 Lifts and platform lifts 6.6.1 Passenger lift
6.6 Lifts and platform lifts 6.6.1 Passenger lift Passenger lifts provide access between different levels and facilitate all users of the building to travel from one floor to another. The obligatory requirements for barrier free provision of lift shall be in accordance with the Design Manual Barrier Free Access. Best Practices are as follows. Lift car: The minimum internal lift car dimensions should be 1100mm wide by 1400mm deep. A passenger lift with internal dimension of 2000mm by 1400mm and door opening of 900mm is recommended where possible.
Lift car that travels between two floor levels can be provided with opposing doors to allow the wheelchair user to travel in one direction.
The wheelchair user needs sufficient space and time to access the lift and an unobstructed area, say 1800mm by 1800mm should be considered in front of the lift. Use non reflective wall and ceiling finish and slip resistant floor finish. Control button and signal: The provision of a large call button at foot level (6.6.1a) in the lift lobby is recommended for people with disabilities. Clear audio and visual signaling (6.6.1b) and messages shall be provided. It is very useful to provide an extended door opening control button inside (6.6.1c) and outside the lift so that the opening time of the doors can be extended with a single press action for access by consecutive wheelchair users and elderly people.
6.6.1b) Provide audio and visual information panel inside the lift car

6.6.1 Passenger lift 6.6.2 Platform lift
Detection device for re-opening of lift doors should take account of slow movers and wheelchair users. The call buttons shall be conspicuous with colour and luminous contrast to its surrounding. Light touch call buttons are recommended. Other provisions: Signage indicating the floor level should be provided on the wall opposite the lift doors on each landing. Provision of information (6.6.1d) with braille markings for frequently visited facilities should be displaced near the floor buttons.
6.6.2 Platform lift Platform lifts are used for vertical transportation to travel between two levels and they could be used when space is restricted. Lift car: Platform lifts should be enclosed with minimum internal dimensions of 1100mm wide by 1400mm deep with a clear opening width of 900mm. The doors should not require the simultaneous operation of two mechanisms to open them and preferably be automatic.
The hand rail inside the lift car can be extended to turn up at lift door opening side as indication.
Provide an unobstructed area of 1500mm by 1500mm in front of the platform lift entrance. This area should be level and kept clear of obstructions to allow access to the lift controls.
Provision of a seat inside the lift should be considered for lifts that are intended to serve mainly elderly people.
Use non-reflective and slip-resistant wall and floor finishes.
When vision panels are fitted, the base of the vision panel should not be higher than 500mm above floor and should be of a minimum height of 1500mm. Control button and signal: The controls should be capable of being used independently by the user and should be higher than 900mm from floor level and not more than 1200mm. The platform lift should incorporate audible and visual alarm as well as emergency systems. Clear audible and visual instructions should be provided.

Stairways, escalators and travellators 6.7.1 Steps and Staircases
6.7 Stairways, escalators and travellators 6.7.1 Steps and Staircases Staircases and steps should not be used as the main means of vertical circulation if alternative means such as ramps (6.7.1a) or lifts (6.7.1b) are feasible. This is because staircases cannot be used by wheelchair users and are not easily negotiated by a number of users, e.g. ambulant disabled persons, pregnant women, young children and elderly. PNAP 266 - The 150mm level difference between the floor next above the external ground or adjoining flat roof as required under B(C)R 35 and 49(1) may be exempted if means to guard against the ingress of water to the inside of the building are provided. Slopes not steeper than 1:20 or ramps not steeper than 1:12 should be used to replace the 150mm step at all entrances/exit to buildings wherever feasible. The priority choices in means of access provision are shown in the table below (6.7.1c).
The whole width of the entrance / exit is accessible with a slope not steeper than 1:20

Means of access
6.7.1b) Use lift for vertical circulation
Stairlifts are not means of barrier free access. Facilities requiring barrier free access will not be considered satisfying the barrier free access requirement if only stairlifts are provided without an alternative accessible route. Stairlifts (6.7.1e) should not be used in any new design of buildings. The use of stairlifts in existing building should be the last option to be considered only if all other means, such as ramps, lifts, alternative routes, lifting platforms and provision of alternative facilities, are not feasible.
6.7.1a) Use ramp for vertical circulation
6.7.1d) Provide signage for accessible route
An alternative accessible route, e.g. by means of a lift or a ramp, should be provided nearby within sight from the position of the staircases. If the accessible route is not available within sight, appropriate signage (6.7.1d) should be provided to guide users in need to the accessible route.

6.7.1 Steps and Staircases
DMBFA97 - 4.4.2(e) The top nosing of any flight should not be less than 300mm from the point at which the adjoining wall returns. Best practice should be 600mm (6.7.1f) in order to have the tactile warning strips not placed along the passageway. DMBFA97 - 4.4.2(g) Best practices : (a) light fixtures should not be mounted only at the ceiling of the landings in order to avoid the person's own shadow casting on the steps while traveling downwards; (b) natural lighting, if provided, should not be provided only at the end of the landings in order to avoid glare; and (c) a lighter colour steps and wall/ceiling background with darker colour/luminous contrast of the nosing tiles, tactile warning strips and railings would achieve a better result than the vice-versa with darker background and lighter objects, because the illumination level would be higher with the same light source.

Architectural Services Department
In places intended to be used frequently by children, such as school, children playground, park, library (with Children section), museum, swimming pool, etc., an additional handrail (6.7.1g) should be provided at a lower height of, say 700mm to 800mm above any nosing, floor or landing for use by children. In addition to the handrails provided on both sides of the staircases, intermediate handrails (6.7.1h) should be provided for staircases with a width wider than, say, 3600mm for external staircases or 2400mm for internal staircases (1800mm for fire exit staircases under MOE). The intermediate handrails should be capable of being used from both sides. When handrails are not continuous, they should return to the wall (6.7.1i), floor or post, so that they do not become obtrusions. Protect the underside of staircases (6.7.1j), where the headroom is 2000mm or less from the finished floor level, with a guard rail or design in such a way to

Generally, people with a guide stick can detect an area of obstruction up to 685mm high from the ground level. 6.7.2 Escalators Escalators are effective means of circulation, capable of moving large crowds continuously and efficiently, however escalators do not provide barrier free access routes. If escalators are used, the following best practices should be considered. An alternative accessible route, e.g. lift or ramp, should be provided nearby within sight from the position of the escalators (6.7.2a). If the accessible route is not available within sight, appropriate signage (6.7.2b) should be provided to guide the users in need to the accessible route.
The recommended clear signals (6.7.2c) for going up/down for escalators under DMBFA97: 5.9.1(a) should be provided if the environment and situation allow.
6.7.2a) Provide a lift near the escalator
6.7.2c) Provide clear signal for going up/down
6.7.2b) Provide signage for an accessible route
6.7.2d) Provide tactile warning strip
Tactile warning strips (6.7.2d) should be provided around the escalator pits both at the top and bottom of the escalator. Sufficient illumination should be provided at the top and bottom of the escalators. Sufficient clearance from any obstruction should be provided to any open side of the escalators (6.7.2e). Escalators should not be used to replace staircases when they are switched off, because the steps of the escalators are not negotiable by many users. If the escalator is installed in a place accessible by users at time when the escalator is not switched on, a lift (not locked) or a staircase should be provided in close proximity to the escalator. The underside of an escalator where the headroom is 2000mm or less from the finished floor level, a guard rail (6.7.2f) or other form of barrier shall be provided to stop people from walking underneath that part of the escalator.

6.7.3 Travellators 6.8 Way Finding and Signage 6.8.1 Way finding and signage strategy 6.8.2 Information
6.7.3 Travellators Travellators are means of horizontal circulation for moving large crowds continuously and efficiently, where a long horizontal point to point travel is required, such as traveling in airport terminals, and train stations. Travellators are not common in Hong Kong. If travellators are used, the following best practices should be considered. Tactile warning strips should be provided at the entrance and exit of the travellators (6.7.3a).
6.8 Way Finding and Signage 6.8.1 Way finding and signage strategy Way finding and signage (6.8.1a) strategies should include the following:• Information about services and facilities; • Direction to facilities and functional spaces, reception, advice, exits and key areas; • Identification including room signs and room numbers, facilities and equipment, stair signs and floor numbers; and • Safety notice such as warnings, prohibitions, hazards, fire exits and refuges.
The direction of travel should be clearly indicated (6.7.3a).
The level of the travellator should align with the floor level at the entrance and exit (6.7.3a). The raised type of travellator with the main level of the travellator raised and connected with a ramped section of travellator at the entrance and exit should be avoided.
Words, pictorial signs and symbols should be used consistently within the same site and building. 6.8.2 Information Facilities for persons with a disability should be clearly and consistently signposted at ramps, carparking spaces, entrances, toilets, baby caring facilities, lifts, reception areas, counters (6.8.2a), accessible routes and exits externally and internally.

6.8.3a) Comprehensive visual and tactile directory at main entrance
Visual directory and map: The directory should show the layout plans in simplified form indicating individual rooms, entrances and cir cula ti on ar eas, toil ets and other accommodation.
6.8.3 Directory and floor plan Directories and floor plans, where provided, should be located at the main entrance to a building (6.8.3a), or in a designated place on the floor of entry, and at other strategic locations on different floors and levels. Although they should be located at a prominent position, they should not obstruct the general pedestrian flow.
Floor levels should be represented in graphical form and reflected in the directory. For good legibility, the information surface of the directory should be faced with non-reflective and glare resistant material. Characters and symbols should contrast with their background.
Bottom level of directories should be at a maximum height of 900mm from floor level. They may be free standing or wall mounted and with 'You are here' indicated. For free standing ones, they should ideally be slightly inclined from the horizontal, in line with the building's orientation.
Tactile map: Tactile maps should be considered at major locations showing directions to the building (6.8.3b). In buildings where finding locations independently on a routine basis is a necessity, tactile maps or prerecorded instructions containing information on locations of main entrances, toilets (6.8.3c) and other major facilities can be very helpful to visually impaired people.

Raised borders and decorative elements that are not required should be separated 9.5mm minimum from tactile characters. 6.8.4 Identification and room signs Many people with disabilities have limitations in movement of their heads and have reduced peripheral vision. Signage positioned perpendicular to the path of travel is easiest for them to notice (6.8.4a). People can generally distinguish signage within an angle of 30 degrees to either side of the centerlines of their faces without moving their heads. Room sign: Signage indicating room names and room numbers should be placed on the wall next to the door on the door handle side or on the nearest adjacent wall.

Illumination levels on the sign surface should be in the range of 100 to 300 lux and shall be uniform over the sign surface. Signs shall be located such that the illumination level on the surface of the sign is not significantly exceeded by the ambient light or visible bright lighting source behind or in front of the sign.
Contrast: Materials for signs should have a non-reflective surface. An eggshell finish is recommended. Signs are more legible for persons with low vision when characters contrast with their background by at least 70 percent. Contrast in percent shall be determined by2: Contrast = [(B1 - B2) /B1] x 100, where B1 = light reflectance value (LRV) of the lighter area and B2 = light reflectance value (LRV) of the darker area. [ 2 from ADAAG Standard ] Colour: Signage, and symbols within signs, should have colour and luminance contrasted with their background (6.86b). The greatest readability is usually achieved through the use of light-colored characters or symbols on a dark background.

6.8.7 Text Visual test: Text on signs should be clear and simple with font style like 'sans-serif'. Visual text should not be made up of capital letters only. Characters should preferably be uppercase or lowercase or a combination of both, conventional in style, and preferably not be italic, oblique, script, highly decorative, or of other unusual forms. Avoid long lists of items on signs. Shorter columns are easier to read and remember. The text dimension of English letters and visual characteristics are listed in the table below for reference. In general, Chinese characters can be one size larger.
Tactile characters shall be raised 1mm minimum above their background and should be accompanied with braille directly below the text. The depth of any embossing should be at least 1.5mm. Raised characters are preferred to be at least 15mm high but not higher than 50mm measured vertically from the baseline of the character based on the uppercase letter "I". Braille shall be located below the corresponding text and preferably be justified to the left. If text is multilined, Braille shall be placed below the entire text. Braille shall be separated 6.4mm minimum from any other tactile characters.
Tactile text and Braille (6.8.7a and 6.8.7b): For tactile text, all characters should preferably be uppercase in simple font style such as sans-serif.

6.9 Tactile Surfaces 6.9.1 Tactile on walking surfaces 6.9.2 Use of tactile surfaces
6.9 Tactile Surfaces 6.9.1 Tactile on walking surfaces Tactile surfaces are used for guidance paths (6.9.1a), information and warning to openings and edges for the visually impaired. There are three types of tactile surfaces (6.9.1b and that are commonly used to guide and alert people. 6.9.1c)
Directional tile: It consists of raised parallel bars to guide people along the direction of a tactile path. Warning tile: It consists of raised truncated domes arranged in square grid parallel to the sides of the tile to alert people of potential hazards such as top and bottom of stairs, door openings and at pedestrian crossings. Positional tile: It consists of raised small dots arranged in staggered positions to indicate change of walking direction.
The obligatory requirements and guidelines for tactile path and tactile arrangements shall be in accordance with the following:• Design Manual of Barrie Free Access 1997 published by Building Department; and • Transport Planning & Design Manual - Facilities for People with Disabilities issued by Transport Department. 6.9.2 Use of tactile surfaces In designing an access to a facility or building, the selection of floor materials may be different for exterior or interior environment. In all cases, it is important to bear in mind that the tactile surfaces should be firm and slip resistant (6.9.2a). Broken tiles or incorrectly laid tiles give wrong information to the user and become an obstacle.
Tactile surfaces should be in colour and luminous contrast with adjoining surfaces, either light-on-dark, or dark-on-light. The material used to provide contrast should be an integral part of the walking surface.

6.9.3 Detectable warnings at vehicular areas A continuous detectable warning strip should be provided to the boundary between the areas of a walkway which crosses or adjoins a vehicular road, and the walking surfaces should not be separated by curbs, railings or other elements between the pedestrian areas and vehicular areas.
It is desirable for tactile surfaces used on interior surfaces (6.9.2b) to differ from adjoining walking surfaces in resiliency or in the sound made by contact with the guiding stick of the visually impaired. Tactile surfaces should convey meaningful and continuous information to the user. For example, the tactile guide path to the lift lobby should lead to the lift button position and then the lift door opening position. The call buttons and other associated information in Braille should convey the necessary information to complement accessibility.

6.10 Assistive Listening Systems 6.10.1 The hearing problem
6.10 Assistive Listening Systems 6.10.1 The hearing problem A hearing-impaired person has to hear the signal, with or without hearing aids, in order to understand it and loudness is just one part of the listening equation. For most people with hearing loss, the comprehension of verbal messages takes more than audibility. Their comprehension also depends upon the nature of their hearing losses. The most common problem in hearing which affects older persons in particular is that hearing acuity is poorer at the higher frequencies than at the lower ones. The acoustic characteristics of speech that allow listeners to distinguish between speech sounds occur largely in the higher frequencies. The common complaint of people with hearing loss is that they can "hear" the low frequency components of speech signals and know someone is talking, but they cannot "understand" because many of the important higher frequencies are filtered out by their hearing loss.
The sound signals which traverse acoustical space before arriving at a listener are weakened by proportion to the travel distance and distorted by background noise reverberation and other acoustical conditions before reaching the listeners. The situation will not be improved just by increasing loudness. The approach is to take appropriate steps so that communications with people with disabilities are as effective as with the general public. Assistive listening systems are useful for effective communication with the hearing impaired (6.10.1a). With such auxiliary aids, a hearing impaired person can enjoy equal opportunity to the benefits of an activity, a service, or a programme. User requirements are the prime consideration in determining what type of assistive listening system would be appropriate for a venue.
6.10.1a) Provide assistive listening system

6.10.2 Types of listening systems
6.10.2 Types of listening systems There are two types of listening systems, namely public address system and assistive listening system. Public Address (PA) System: The PA System utilizes the loudspeaker(s) to transmit sound signals to the listener. In buildings to be used by the public, the visual display boards should also display relevant information announced by the PA system. An example is the train schedule information.
Assistive Listening Systems (ALS): ALS are devices used in venues such as theatres, auditorium, convention centres, courtrooms, museum to help people with hearing loss to improve their auditory access in difficult and large-areas. A free standing ALS can be used to back up the existing PA system but it is not a substitute for PA system. It can also be used to improve functional hearing abilities with or without the person wearing hearing aids.
ALS are intended to augment standard public address and audio systems by providing signals which can be received directly by persons with special receivers or their own hearing aids and which eliminate or filter background noise. The type of assistive listening system appropriate for a particular application depends on the characteristics of the setting, the nature of the program, and the intended audience. Three types of ALS are listed below:• Magnetic Induction Loop (IL) systems use a wire around the room to transmit an electromagnetic signal that is picked up by a small telecoil in the hearing aid (6.10.2a). Users simply switch on the telecoil (the "T" setting) and adjust the volume of the hearing aid. However, telecoils (mainly used for improved telephone access) are found in about thirty percent of current hearing aids. For those people whose hearing aids contain telecoils, an IL system is very convenient as the special "receiver" is their own hearing aids.

6.10.3 Installation of ALS
• FM (Radio Frequency) systems are variations on the commercial FM radio. Radio signals are broadcast by an FM transmitter backed on the sound system used in the facility. These signals are received by individual "radios" - small pocketsize receivers tuned to the specific frequency used in the transmission. • Infrared (IR) systems operate on infrared light that is beamed from one or several IR transmitters to small, specialized receivers. There are several types of IR receivers such as stethoscope-style that dangle from the ears, a headset type that fits over the ears, and a small pocket-size type similar to the FM receiver. The receiver-to-ear connections for the first two types are straightforward as they are placed directly in or at the ear. The receiverto-ear connections with the pocket-style are the same as FM receivers.
6.10.3 Installation of ALS Each ALS has its advantages and disadvantages. A system that works well in a courtroom may not be appropriate for a theater. An outdoor facility needs a different system from that of an orchestra hall. Differences in requirements such as privacy, interference, cost, installation requirements may result in installation of different type of ALS in a venue. A site analysis and operation assessment is required before deciding which system would be the most appropriate ALS for the venue. Some of the aspects that should be considered are listed below:• If privacy is a major consideration and the events taking place should be excluded to people outside the room, then an IR system should be employed.
• If a large number of simultaneous events are to be taking place in adjoining facilities and there are a sufficient number of potential FM carrier frequencies available to ensure non-interference between rooms, then a FM system is a possibility. Other

6.10.3 Installation of ALS 6.10.4 Management of ALS
considerations include the provision of FM receivers that can be tuned to all the possible frequencies. • If it is necessary to use the system alternately in a number of different activity rooms such as in a community center, then FM systems are more flexible and can be used both indoors and outdoors. However, some IR systems are also relatively easy to deploy, and portable units work well in smaller activity rooms, although they are less effective outdoors.
• If the facility is very large such as the case of a massive auditorium with balconies and overhangs, it is easier to provide an appropriate signal at all seat locations with an FM system although an IR system in such location can be considered. • If the facility is likely to be subjected to persistent interference, then an IR system may be the best choice. It is possible to use a frequency scanner to determine the possibility of interference.
6.10.4 Management of ALS Some of the common problems that are encountered with the system:• Staff are unfamiliar with using the system or do not know how to demonstrate it. • The batteries in the receiver are either dead or weak. • The receiver/ear connection is not suitable or incompatible for the user. • The equipment is of poor quality and could not provide the acceptable standard. • The ALS was not installed properly or maintenance is required. Proper maintenance of the system and training of staff are important. Information regarding availability of the system and receivers should be located in a conspicuous location or can be obtained at an information counter or the box office. It is necessary to consider storage space and battery charging facilities for such devices.
It is recommended that professional advice, preferably one with experience in installing ALS's should be obtained for major facilities, particularly the larger ones, before purchasing any system.

New photo restrictions raise worry about freedom in New York
An axiom runs through our legal training as journalists: There's little privacy in public.
The hypothetical scenario hasn't changed in decades: If a couple does something illicit in their house. That's private. If they do it on the street corner, that's public. If they do it in front of the living room picture window for anyone to see from the street? Public. But if the activity requires a witness to crawl through the bushes to look in the window, that's private.
However, bills winding their way through the state Legislature and on Gov. Andrew Cuomo's desk would turn any number of public places — from the side of the road, to a parking lot, to a front door of a public building — to private places at the discretion of government officials.
The first bill, sponsored by Assembly Member Edward Braunstein (D-Queens) and Sen. Liz Krueger (D-Manhattan), might seem to have honorable intent. It would prohibit photos or video of someone receiving treatment in a medical facility.
Federal law already prohibits that, under the Health Insurance Portability and Accountability Act. This bill would extend that ban to anyplace treatment is provided, such as the side of the road where medics are treating the injured following a crash.
The latest federal guidelines created in a number of cases — including Onassis vs. Galella in 1973, Daily Times Democrat vs. Graham in 1962 and Neff vs. Time in 1976 — create standards that suggest images must be both highly offensive and of no legitimate news value before photographs can be prohibited. We wonder whether the state law could survive a constitutional challenge.
Privacy is important, we agree, but so is a free and unfettered ability to observe and report news in the public interest. Emergency workers providing aid to the public is inherently in the public interest. These people are doing their jobs — and we hope doing them well. It's good that you should know that.
A second bill, proposed by Assembly Member Inez Dickens (D-New York) would make photographing anyone entering or leaving a reproductive health facility a crime. Again, the intent might seem noble — preventing people from using photography or video to shame someone seeking to use those services. (You might think abortion, but these facilities provide everything from family planning to birth control to basic gynecological care.)
However, the law would also ban video images of protests or the very harassment the law is intended to prevent. Again, the images are important to public understanding of what's happening in the community. The law would leave people who might hinder access to such a clinic unfettered rein — so long as they don't take pictures.
Following on the adoption of a state law banning the disclosure of the mugshots of people accused of crime, these bills create too many instances where police agencies get to decide what you know, when you know it and how, regardless of whether that information hinders a criminal investigation or discloses the identity of an undercover investigator — two very legitimate reasons to keep information from the public.
When the government has that much authority over what should be public knowledge, we edge far too close to that concept we call "a police state." We urge Gov. Andrew Cuomo and state legislators to drop these efforts before more damage is done to your right to know.

In light of Singapore's ageing population, calls for ambulances and emergency are expected to increase 6% annually according to the Home Affairs Ministry — and the project aims to address the problem, remarked Minister for Defence, Ng Eng Hen on 23 May.
"The SAF's primary mission is to defend the nation against external threats. But, in the area of emergency care — using SAF medics to respond to civilian emergencies is synergistic and mutually helpful," highlighted Dr Ng at the opening of the Asia Pacific Military Health exchange.
Reduction in manpower forces SAF to take measures
The SAF will have its manpower reduced by one-third from 2030 onwards, therefore it must respond decisively to the reduction in manpower supply by helping out civilians.
"Because of our manpower constraints, each soldier is valuable, whose contributions need to be optimised and put to full use for the nation's defence," said Dr Ng, who also acknowledged military medical practitioners for their contributions in humanitarian aid in disasters, pandemic and terrorism control, and care and rehabilitation for casualties, among others.
"It will meet the growing demand as well as allowing our medics to keep their skills current, to better respond in times of military crises," he added.
The event witnessed 500 delegates comprising senior military officers, active service and reserve medics, nurses, allied health professionals and defence researchers from Asia Pacific countries to discuss the latest in military health and medicine.
The pilot partnership will involve 12 SAF medics, of which 10 are full-time national servicemen and two are regular servicemen. All will work closely with SCDF personnel to respond to civilian medical emergencies.
Investments in military medicine affects civilians, too
Vocation requirements for the SAF Medical Corps are also being reviewed to be more flexible to allow more soldiers to be deployed to the vocation. Many of the platforms can also be operated more simply with the help of automation, added Dr Ng.
The review is expected "to be completed soon and implemented progressively over the next few years", he asserted.
The army has also set up a new Centre of Excellence for Soldier Performance to redesign fitness training to enhance the potential of every soldier.
"It allows our medical professionals to work with the training community and sports scientists to increase the potential and enhance performance of every soldier," he explained.
Dr Ng also further stated that investments in military medicine will pay off in better treatment not just for soldiers, but civilians as well.
"History has shown that when care for soldiers is improved, better care for civilians will ensue, and vice versa. The two fields are mutually reinforcing," he said. MIMS

Lipozene Weight Loss Pill Review
Lipozene weight loss pill is another product that claims to contain all natural products. This was developed by the Obesity Research Start LLC which has been historical known to have issues regarding credit credit card scams. However, there are no complaints from their customers regarding this problem. The product states contain natural ingredients thus, safe and healthy to use although the only known ingredient in Lipozene is Glucomannan. This is a fiber that was extracted from Konjac underlying. This ingredient is thought to treat constipation, increase cholesterol level, and obesity.
Although Lipozene is probably the popular weight loss popular products, this product isn't approved by the Food and Drug management. The item also contains a tiny amount of vitamins, green teas, and koala nut yet the only active ingredient is glucomannan.
It is recommended that you take Lipozene 2 capsule, thrice a day thus a total of 6 capsules daily. The product claims that it is a weight loss supplement that helps in reducing your weight and body fat safely and effectively. Up to now, the process of how Lipozene works to support in weight loss carries on to be unknown. Nevertheless, based on a clinical demo, the active ingredient, glucomannan works through making a sense of fullness and decreasing the caloric intake that helps in suppressing the appetite and regulating bowel movement.
The main benefit of Lipozene is its main ingredient lipozene glucomannan which is a natural fiber. Furthermore, the product is supported with a clinical trial. Plus, customers can obtain free trial samples of the product to determine first whether the product is secure and efficient before buying in bulk. However, it also has its drawbacks which can be generally due to the insufficient information on the product's official website. It does not also help in shedding fat which it claims to do. The product also has a lot of negative feedbacks and reviews from its consumers and is backed up with an unreliable manufacturer.
Lipozene is actually a risky weight loss product as a result of inadequate information about the product's components. Without the complete set of the ingredients, you are uncertain whether the product is safe and effective to use. Furthermore, bottle of Lipozene cost $30 which contains 60 capsules. This will only last for 10 days thus per month supply will cost $90 which is actually expensive compared with other weight damage supplements. It is advised to make use of other weight reduction products with a reputable manufacturer, and safe and effective product.

In the context of an application lifecycle, middlewares are defined as special functions that have access to the request (req) and response (res) object along with the next() function located in the pipeline.
The code snippet above depicts a basic way of defining a middleware function in an express application and loading it in the request handling pipeline.
Having put aside the obligation of giving a fancy definition, first up, let's actually get down into what exactly are these middleware functions used for and what are the different ways in which we can inject them in an express application lifecycle.
The code provided below demonstrates the setting up of a basic Express application.
We'll go through it line by line and try to understand how and where the middleware functions fit into the overall scheme of things.
The first three lines do the basic configuration of setting up the express module and make the application runnable and listen to requests at a specific port number. (It looks if the port number is already configured in the form of an environment variable, if not it explicitly sets the port number to 3000).
Next comes the job of adding middlewares to the express request handling pipeline. Note that all the middlewares are wrapped inside the app.use() method.
Next comes the custom middleware which kind of simulates a logic to perform some authentication on a protected route before actually moving the execution to the request handler. In our example, we take the assumption that we are making the request to the route "/books" as an anonymous user without any authentication and thereby, any attempt to access the mentioned route should be returned with a status code of 401 (Unauthorized). Otherwise, if the user makes a request to some other route, the middleware will do its job and the request will then flow down the pipeline to execute the next middleware or request handler. In this case, it shall move to the next middleware.
This middleware shall simply log the time of the request to the console which in a way can be seen as an analogue to performing some kind of logging before the request is processed by the application.
Note that if we omit the next() call here and the user makes a request to the "/" route, the request will not be able to move to the request handler and the application will get stuck.
After traversing down a couple of middlewares, then if the request url matches to the root route i.e. "/", the request handler provided above shall be triggered and shall return the desired response back to the browser. Post sending the response, the next() function will again invoke the next middleware if any is in the request pipeline.
This middleware function does the cleanup work post request handling which in this case is simply logging something to the console. Note that this middleware gets invoked specifically when the "/" route is accessed by the user as denoted by the first argument to the app.use() method. This implies that we can also cause a middleware to be included in the pipeline only when the request is made to a specific route.
One more thing that needs to be taken into account is the order of execution of the middleware functions. The functions get executed in the same order in which they are declared.
As a brief side note, Express also provides us with an error handling middleware that automatically takes care of catching the exception encountered in any of the middlewares in the pipeline and then aggregates them and sends back as a response.
That's all I have for Express middlewares. Please feel free to drop in your views on the same as I look forward to being back with some more interesting content very soon.
Happy Coding!!!
