The Public Protection Classification (PPC) program recognizes the efforts of communities to provide fire protection services including water supply and distribution, (911) receiving and handling fire alarms , and fire department capabilities. Some insurance companies use the PPC information to help establish fair premiums for insurance. By offering economic benefits for communities that invest in their firefighting services, the PPC program provides additional incentives for improving and maintaining public fire protection. The PPC program also provides help for fire departments and other public officials as they plan, budget and justify improvements. The most significant benefit of the PPC program is its effect on fire losses. The better the fire protection, the lower the fire losses. This results in lower insurance rates
