Which class of standpipe is intended for use solely by building occupants?

The class of standpipe designed specifically for use by building occupants is Class II. This type of standpipe system is aimed at providing a readily available means for occupants to combat small fires or assist in their evacuation before professional firefighters arrive. Class II standpipes are typically equipped with 1.5-inch hoses and are located in accessible areas, enabling trained occupants to use them effectively.

These standpipes generally serve several key purposes: they empower building occupants to take immediate action, they are easy to operate, and they do not require advanced training to use. Thus, the Class II standpipe plays a crucial role in enhancing safety within the building by allowing occupants to respond rapidly to fire emergencies.
