ISO Mitigation SLIDERS v03 Fire

ISO’s Fire Suppression Rating Schedule (FSRS) lists a large number of items a community should have to fight fires effectively and assigns credit points for each item. Using those credit points and various formulas, ISO calculates a total score on a scale of 0 to 105.5.

To receive certain Public Protection Classification (PPC™) ratings, a community must meet minimum criteria:

  • minimum facilities and practices to get a PPC rating
  • minimum criteria for Class 9
  • minimum criteria for Class 8B
  • minimum criteria for Class 8 or better

After a community meets those criteria, the PPC depends on the community’s score on the 100-point scale: PPC Points
