ISO Mitigation SLIDERS v03 Fire

The Fire Suppression Rating Schedule (FSRS) does not specify any maximum age for fire apparatus. ISO uses National Fire Protection Association (NFPA) standards to determine whether the apparatus meets general requirements. ISO will credit a pumper with its demonstrated capability (gallons per minute, gpm) at a net pump pressure of 150 psi. Aerial apparatus must pass a nondestructive test at least every 5 years.
