What is Tellico Village Volunteer Fire Department's ISO Rating?

TVVFD's ISO Public Protection Classification Rating is 4/4x.

What is ISO Rating?

ISO stands for Insurance Services Office a for profit corporation that analyzes municipal fire protection efforts in communities throughout the United States though its “Public Protection Classification” (PPC) program.

In each community, ISO analyzes a variety of data using its Fire Suppression Rating Schedule (FSRS). The Fire Suppression Rating Schedule is a manual ISO uses in reviewing the fire-fighting capabilities of individual communities. The schedule measures the major elements of a community's fire suppression system and develops a numerical grading called a Public Protection Classification. ISO then assigns a Public Protection Classification rating from 1 to 10. Class 1 represents an exemplary public protection, and Class 10 indicates that an areas fire suppression program does not meet ISO's minimum criteria.

How does the ISO rating affect residents?

Enhanced safety is the chief benefit of an improved ISO rating. Statistical data shows a direct

relationship between better fire protection and a reduction in injuries and property loss.

Beyond keeping people safe, an improved ISO rating generally results in lowered property


What makes up an ISO rating?

The ISO Public Protection Classification consists of three major components:

• Fire Department- 50%

• Fire Communications: Receiving & Handling Fire Alarms - 10%

• Municipal Water Supply - 40%

Fire Department
Fifty percent of the overall grading is based on the number of stations, apparatus, staffing and training. ISO checks that the fire department tests its pumps regularly and inventories each engine's equipment i.e. hoses, nozzles, breathing apparatus etc..

ISO also reviews the fire company records to determine:

  • Type and extent of training provided to personnel
  • Number of people who participate in training
  • Firefighter response to emergencies
  • Maintenance and testing of fire department equipment

Fire Communications Receiving & Handling Alarms
Ten percent of the overall grading is based on how well the fire department receives fire alarms and dispatches its fire-fighting resources. Field representatives evaluate the communications center, looking at the number of operators at the center; the telephone service, including the number of telephone lines coming into the center; and the listing of emergency numbers in the telephone book. Field representatives also look at the dispatch circuits and how the center notifies firefighters about the location of the emergency.

Water supply

Forty percent of the grading is based on the community’s water supply. This part of the survey focuses on whether the community has sufficient water supply for fire suppression beyond daily maximum consumption. ISO surveys all components of the water supply system, including pumps, storage, and filtration. To determine the rate of flow the water mains provide, we observe fire-flow tests at representative locations in the community. Finally, we evaluate the distribution of fire hydrants.
