It can refer to a piece of equipment and operator, and less often to multiple people working together. Facilities ICS uses a standard set of facility nomenclature. ICS facilities include: pre-designated incident facilities: Response operations can form a complex structure that must be held together by response personnel working at different and often widely separate incident facilities. These facilities can include: Incident command post (ICP): The ICP is the location where the incident commander operates during response operations. There is only one ICP for each incident or event, but it may change locations during the event. Every incident or event must have some form of an incident command post. The ICP may be located in a vehicle, trailer, tent, or within a building. The ICP will be positioned outside of the present and potential hazard zone but close enough to the incident to maintain command. The ICP will be designated by the name of the incident, e.g., Trail Creek ICP. Staging area: Can be a location at or near an incident scene where tactical response resources are stored while they await assignment. Resources in staging area are under the control status. Staging areas should be located close enough to the incident for a timely response, but far enough away to be out of the immediate impact zone. There may be more than one staging area at an incident. Staging areas can be collocated with the ICP, bases, camps, helibases, or helispots. A base is the location from which primary logistics and administrative functions are coordinated and administered. The base may be collocated with the incident command post. There is only one base per incident, and it is designated by the incident name. The base is established and managed by the logistics section. The resources in the base are always out-of-service. Camps: Locations, often temporary, within the general incident area that are equipped and staffed to provide sleeping, food, water, sanitation, and other services to response personnel that are too far away to use base facilities. Other resources may also be kept at a camp to support incident operations if a base is not accessible to all resources. Camps are designated by geographic location or number. Multiple camps may be used, but not all incidents will have camps. A helibase is the location from which helicopter-centered air operations are conducted. Helibases are generally used on a more long-term basis and include
