A safety cabinet is used for the safe storage of flammable chemical substance or compressed gas cylinders. Primarily, they should meet three major safety requirements: Minimize the fire risks associated with the storage of flammable substances and protect the cabinet's contents for a known (tested) minimum length of time (fire rating). It should prevent the materials stored in the cabinet from contributing to the spread of fire or leading to an explosion in the event of a fire Minimize the amount of vapor released into the working environment Retention of accidental spillages within the cabinet Areas of application and uses are diverse: pharmaceutical, universities, hospitals, industry, workshops, public organizations working with hazardous substances etc. In essence, any facility where flammable substances are stored.

HSG51: The storage of flammable liquids in containers. This Health & Safety Guidance (HSG) publication from the HSE is aimed at anyone who has responsibility for the storage of dangerous substances, regardless of the size of storage facility. It sets out control measures aimed at eliminating or reducing risks to people at work or otherwise from the storage of packaged dangerous goods. It reflects good practice for the design of new storage facilities (and where reasonably practicable, to existing sites) and applies to transit or distribution warehouses, open-air storage compounds, and facilities associated with a chemical production site or end user. HSG140: This Health & Safety Guidance (HSG) publication from the HSE is for those responsible for the safe use and handling of flammable liquids in all general work activities, small-scale chemical processing and spraying processes. It explains the fire and explosion hazards associated with flammable liquids and will help you determine how to control the risks in your workplace. HSG71: This Health & Safety Guidance (HSG) publication from the HSE focuses on the classification of hazardous materials and the relationships of those materials with each other. Particular focus is given to general recommendations for the
