Final answer:
The ISO requires a maximum hydrant spacing of 300 feet in commercial districts and 500 feet in residential areas to ensure sufficient firefighting coverage.
Step-by-step explanation:
The Insurance Services Office (ISO) sets guidelines for the placement of fire hydrants to ensure adequate coverage for firefighting. In commercial districts, the ISO requires a maximum spacing of 300 feet between hydrants. For residential areas, the maximum spacing between hydrants is set at 500 feet. This ensures that in the event of a fire, firefighters have sufficient access to water sources to manage and extinguish the fire effectively. Compliance with these standards is important as it can influence a community's ISO fire insurance rating, which may affect property insurance premiums.
The Insurance Services Office (ISO) requires a maximum spacing of 500 feet between hydrants in commercial districts and 300 feet in residential areas. The ISO is an organization that provides insurance companies with public protection classification information. This information is relevant for determining insurance rates for fire insurance coverage.
