What does a Class II fire protection system provide?

A Class II fire protection system is specifically designed for use in commercial buildings and is primarily intended for the use of trained personnel. This system provides 1-1/2" hose stations, which are easily accessible and suitable for tackling smaller fires or assisting in initial firefighting efforts before the arrival of professional fire responders. The size of the hose is significant because it allows for a higher pressure of water, making it effective for individuals who may need to put out a fire or control smoke.

The system's design takes into account the typical needs of trained personnel in commercial settings. Larger hose sizes would typically be installed in Class I systems, which are intended for use by fire professionals and would require larger diameter hoses (like 2-1/2") to handle more substantial fires. Therefore, the inclusion of 1-1/2" hoses in a Class II fire protection system supports the operational effectiveness of staff on-site while ensuring that adequate fire suppression capabilities are available for potential fire emergencies.
