IT happened on a working house fire a few years ago. I am not proud of what happened but after it happened it changed my thinking on a particular item. I used to wear my helmet like the “TOUGH” firefighters wear it with the chin strap clicked on the brim of the helmet. On this particular fire we made entry into a converted attic into bedroom in a single family residence. Command advised us there were two children inside. We made entry and quickly put out the fire above our heads. As we proceeded up the stairs I stopped and my backup didn’t and the hose hit my helmet and knocked it off and pulled my incorrectly worn hood off my head. Immediately I experienced intense pain on my ears and I backed down the stairs and repositioned my hood but could not find my helmet. I proceeded back up the stairs and continued my search. When I found my helmet it was lying next to a crib. I did find one of the children in that crib and proceeded to remove the child to the outside of the structure. After medical evaluation it was found that I had second and third degree burns to both of my ears. The one thing I learned and I want others to get from this is to always use your chin strap. It is on your helmet for a reason.
