The Fire Suppression Rating Schedule (FSRS) is a manual containing the criteria ISO uses in reviewing the fire prevention and fire suppression capabilities of individual communities or fire protection areas. The schedule measures the major elements of a community’s fire protection system and develops a numerical grading called a Public Protection Classification (PPC™).
Fire Departments across the nation are graded on different components that effect fire suppression including water supply, communications, fire department personnel, and equipment. Departments are awarded a number between 1-10, with 1 being the highest possible granted number.
Charleston Fire Dept. was awarded ISO Class 2
