Which class of standpipe is intended for use by building residents?

Class II standpipes are designed specifically for the use of building occupants who may not have firefighting training. These standpipes are typically equipped with 1.5-inch (38 mm) diameter hoses, which are easier for individuals without specialized training to handle. The intent is to empower building residents to take action in the early stages of a fire when immediate response is vital.

Class I standpipes, on the other hand, are intended for use by fire department personnel and are equipped with larger hose connections for fire service purposes. Class III standpipes combine features of both Class I and Class II, allowing for both trained personnel and occupants to use the system, but they still involve larger hoses that may be more challenging for the average resident. Class IV standpipes do not exist in standard classifications, making Class II the clear choice for resident use.
