Which type of standpipe system is designed for occupant use?

Class Two standpipe systems are specifically designed for occupant use, providing a means for building occupants to fight fires themselves before emergency services arrive. These systems are typically equipped with 1.5-inch hoses and nozzles that are easily manageable for individuals who may not have extensive firefighting training.

The intent of Class Two systems is to empower occupants to take immediate action in the event of a fire, thereby potentially controlling small fires or at least limiting their spread until professional firefighters can respond. They are often found in commercial buildings, public assembly spaces, and other facilities where crowds may gather, ensuring that there is an accessible fire-fighting resource for those within the structure.

Other types of standpipe systems serve different purposes. For instance, Class One standpipe systems are intended for use by professional firefighters and are equipped with larger diameter hoses. Class Three combines features of both Class One and Class Two, providing connections for both fire department use and occupant use. Class Four is not a standard classification recognized within the traditional standpipe system guidelines.
