Final answer:
The incident facility used to house out-of-service resources and potentially located with the Incident Command Post is the Base Camp.
Step-by-step explanation:
The incident facility used to house out-of-service resources, which may be located with the Incident Command Post (ICP), is the Base Camp. A Base Camp is a location at which primary logistics functions are coordinated and administered. There, resources can rest, rehabilitate, and prepare for deployment, and it generally includes sleeping areas, food services, and sanitation facilities. It is differentiated from other incident facilities like the Staging Area, where resources are kept on standby for immediate deployment, or the Helibase, specifically designated for helicopter operations. The Emergency Operations Center (EOC) is often a facility that serves as a central command and control center for emergency management, not typically intended for housing resources.
