Which class of standpipe is intended for use by fire department personnel only?

Class I standpipes are specifically designed for use by fire department personnel. They feature a 2.5-inch hose connection that allows firefighters to connect their hoses directly to the standpipe system for effective firefighting operations. These systems provide a reliable water supply in buildings, enabling quick and efficient fire suppression capabilities.

The designation of Class I standpipes emphasizes the need for training and experience in handling them, as they are intended for professionals who understand the pressure, flow rates, and hose management required in emergency situations. This class is typically not accessible to the general public, highlighting the importance of trained personnel for safety and efficacy during fire suppression efforts.
