"The personnel accountability report is utilized in various activities on the fire ground. The use of PAR[PersonAl Responsibility] allows the command staff to know that all personnel are accounted for and not lost or injured. It keeps everyone safe and should be part of all standard operating guidelines. Another important use of PAR for every person in the fire service is the individual's personal accountability and responsibility. Fire service personnel spend an abundance of time in all aspects of fire service operations: fire suppression, prevention and hazardous materials, to name a few. Safety should be stressed in all areas of operation, and in particular the firefighters' well-being. At all times, firefighters and fire officers must become personally responsible for their own actions and at the same time be in compliance with their personnel accountability report."
