According to NFPA 1901, the design flow rate for filling water tenders is required to be at least how many gpm?

The requirement stated in NFPA 1901 for the design flow rate for filling water tenders is set at a minimum of 1000 gallons per minute (gpm). This specification is critical for ensuring that water tenders can be filled efficiently and effectively to support firefighting operations. A higher flow rate allows for quicker refilling of water tanks during emergencies, which can be crucial in maintaining adequate water supply for firefighting efforts.

The rationale behind this standard emphasizes the need for robust and efficient water delivery systems in firefighting, particularly in scenarios where large volumes of water are necessary for suppressing fires. By ensuring that water tenders meet or exceed this minimum flow rate, fire departments can enhance their operational capabilities and responsiveness in responding to fires.
