What is the flow rate requirement for Class I standpipes?

The flow rate requirement for Class I standpipes is a minimum of 250 gallons per minute (GPM). This requirement is established to ensure that sufficient water is available for firefighting operations, particularly for trained firefighting personnel who may utilize the standpipe systems.

Class I standpipes are typically found in commercial and high-rise buildings, designed to provide a reliable water supply for fire department connections, ensuring firefighters can effectively combat fires in multi-story buildings. The specified flow rate of 250 GPM ensures that firefighters have an adequate volume of water to suppress flames and protect property and lives during emergency situations.

Understanding this flow rate is crucial for anyone involved with fire safety and emergency response, as it helps maintain the effectiveness of standpipe systems in various building types, aligning with fire safety codes and regulations.
