What is the flow rate for Vari Nozzles that are used on USCGC STONE?

Vari Nozzles are designed to provide adjustable flow rates for different firefighting scenarios. In the context of the USCGC STONE, the correct flow rate specified is 95 gallons per minute (GPM) for most applications. However, when it comes to Aqueous Film-Forming Foam (AFFF) hoses specifically in the Hangar area, the flow rate increases to 125 GPM. This design allows for increased firefighting effectiveness where higher concentrations of foam are necessary due to the nature of the hazards present, especially in hangar spaces where flammable liquids could be present.

This dual flow rate approach of maintaining 95 GPM generally, but utilizing a higher 125 GPM for AFFF application, aligns with best practices in firefighting. It optimizes the firefighting response by ensuring that adequate resources are available for different situations while maintaining efficiency in less critical areas.
