Class III standpipe systems are designed to allow:

• A. modifications based on local need.
• B. installation on water tanks or towers.
• C. occupants and firefighters to apply water on a fire.
• D. only firefighters and fire brigade members to attack fires.

Answer: (C)

Class III standpipe systems are designed to allow both occupants and firefighters to apply water on a fire. They combine features of Class I and Class II, providing 2.5-inch hose connections for firefighters to connect attack lines and 1.5-inch handline outlets that occupants can use. This setup enables rapid initial intervention by occupants and scalable fire suppression by firefighters from the same system. The other options aren’t correct because a Class III system isn’t about local need-based modifications or installing on water tanks or towers, and it isn’t limited to firefighters only—the design explicitly includes occupant use as well.
