Which standpipe class is intended for use by building occupants only?

• A. Class 1 - Fire Personnel Only
• B. Class 3 - Both Fire/Occupants
• C. Class 4 - Maintenance Only
• D. Class 2 - Occupants Only

Answer: (D)

Standpipe classifications define who should use the system and what size hose it provides. The one intended for building occupants is the Class II system, which supplies a 1.5-inch handline with a nozzle stored within the standpipe for occupants to operate. This design lets occupants take initial action to control a small fire while awaiting firefighters. Class I is for fire department personnel only and uses 2.5-inch outlets, not for occupants. Class III is a combination system usable by both occupants and firefighters, providing both 1.5-inch handlines and 2.5-inch outlets. Class IV is not designed for occupant use. Therefore, the occupant-only option is the Class II system.
