The Insurance Services Office (ISO) evaluates public fire-protection services and classifies a community’s ability to suppress fires.
The Public Protection Classification system provides an objective, national standard that helps fire departments in plan and budget for facilities, equipment and training. And by securing lower fire insurance premiums for communities with better public protection, the PPC program provides incentives and rewards for communities that choose to improve their firefighting services.
The department received an ISO Class 1 rating during its latest evaluation, in August 2013. Mt. Lebanon is one of only three departments in Pennsylvania, and one of only approximately 200 nationally, to have achieved this status. The department had a Class 3 rating from 1988-2013.
