ISO Class 1 Rating
On Monday, December 4, 2006 the City of Mesquite was presented a plaque commemorating an ISO Class 1 evaluation. The Class 1 rating has been achieved by less than 60 communities nationwide.
ISO is the leading supplier of statistical, underwriting, and actuarial information for the property / casualty insurance industry. Most insurers use the PPC classifications (Public Protection Classification) for underwriting and calculating premiums for residential, commercial, and industrial properties.
To determine a community's PPC, ISO conducts a field survey. Expert ISO staff visit the community to observe and evaluate features of the fire-protection systems.
Using a manual called the Fire Suppression Rating Schedule (FSRS), ISO objectively evaluates three major areas:
1. Fire alarm and communications systems. A review of the fire alarm system accounts for 10% of the total classification. The review focuses on the community's facilities and support for handling and dispatching fire alarms.
