The Insurance Service Office (ISO) evaluates fire protection efforts in communities throughout the United States. The ISO produces a Public Protection Classification (PPC) rating for a community based on three factors. These factors include: Fire Alarm and Communications Systems (telephone systems, telephone lines, staffing and dispatch systems) Fire Department (equipment, staffing, training and geographic distribution) Water Supply (condition and maintenance of hydrants, available supply vs. fire flow requirements The PPC rating is utilized by insurance companies to set insurance premiums for the community. Fire departments also utilize the PPC rating as a benchmark for measuring the effectiveness of the services they provide for the community.
