I was originally hired as an Emergency Medical Technician by a hospital. After a few years the local Fire Department took over EMS. The only thing that changed is that the taxpayers had to pay to have our ambulances repainted and we all got new uniforms.
One day while driving my partner and I get flagged down; the man’s truck had caught fire. We could see visible flames between the cab and the box. My partner grabbed the fire extinguisher on the console and I ran around to the back and got the fire extinguisher from the rear compartment. We doused the flames before the engine arrived. We made our report on the radio and went back to the station to restock.
We were later told that the fire extinguishers should only be used if our vehicle was on fire, and not for civilians.
So, we were supposed to sit in Fire uniforms, in a Fire vehicle, and not put out a fire.
