Which occupancy category is defined as housing where 4 or more people cannot evacuate on their own?

• A. Dormitory
• B. Mercantile Occupancies
• C. Health Care and Ambulatory Care Occupancies
• D. High Rise

Answer: (C)

Understanding who can evacuate on their own is the key idea here. Some buildings house people who may not be able to leave without help, so the life-safety plan must account for that need. Health care and ambulatory care occupancies are defined to include spaces where occupants—such as patients or residents with mobility or medical limitations—cannot evacuate unaided. The rule about four or more people needing assistance flags this category, ensuring requirements like staff-to-evacuate, alarms, and protected egress are in place so everyone can exit safely. This differs from a dormitory, which is a residential setting where occupants can typically evacuate by themselves; mercantile occupancies are retail spaces where patrons usually evacuate independently; and high-rise refers to building height—it's about the structure and its required egress systems rather than occupant impairment.
