Watching our local fire dept practice with the ladder truck in the nearby church parking lot,
I thought it would be a good time to ask the truck operator "What does PAR stand for?"
He said "Personnel Accounting and Reporting" Then he opened the door of the truck to show a board.
It had three columns and used magnetic name plates. The columns were:
AT TRUCK, AT SCENE OR FIRE, and AT REHAB
Fire depts all over the U.S. learn from each others successes and mistakes.
When an effective protocol is developed that reduces risk, most fire depts like to adopt it.
So whatever fire dept you are listening to, PAR means basically the same thing.
Are all of your firefighters accounted for?
