While performing a live fire evolution the nozzle man didn’t recheck his setting on his automatic nozzle while in the burn room. The nozzle was purged outside and set on straight but while advancing, they let the nozzle drag and it switched to a wide fog. Ceiling temps recorded about 900-1000 degrees. It only took 2-3 seconds for him to realize what he did but it was to late. I had to pull my 2 guys out of the room while we could. NO ONE WAS INJURED THANK GOD. The turnout coats was badly discolored and reflective was burnt off and melted some bourkes. Had we been in there for a little longer it would have been much different
LESSONS LEARNED: I have been a firefighter for 10 years. Automatic nozzles are still my number one choice in nozzles but YOU NEED TO MAKE SURE OF YOUR SETTINGS. Have more nozzle discipline. I’m sure he or anyone in my group would make the mistake again.
