Several years ago, myself and a Captain responded to a car fire on the interstate. At the time, our usual response was a brush pumper, with a tanker only on request for more water. A city police officer just happened to respond as well. Because of the wind direction we positioned our truck in front of the fully involved vehicle that was parked on the shoulder of the interstate. The officer parked his patrol car some distance behind the car and directed traffic from the median. After knocking down the fire, my captain went to retrieve an axe to open the hood, while I waited by the front bumper of the car. Suddenly I heard a loud crash. Unable to see what was coming because of the steam and smoke coming from the car I stayed at the bumper. A split second later I found myself flying through the air. The noise I heard was a drunk driver hitting the patrol car, which launched his Blazer into the air before striking the back of the car at about 55 mph. I was knocked out of my boots and sent bouncing over the top of the car. After a couple of surgeries to repair my right knee, getting over a concussion, and broken bones had healed, I finally returned to work 7 months later. As a result, our department changed our SOGs for responses on the interstate to include an engine or tanker to use as a blocking vehicle and to have SCBAs in use. I wish I could say it was followed all the time.
