Re: Backdraft of Semi Trailer Kills Battalion Fire Chief
Your mother didn't teach you that you shouldn't open a pressure cooker on the stove. |

Re: Backdraft of Semi Trailer Kills Battalion Fire Chief
From the report. "Fire service training should provide insight and education towards commonly unrecognized pressure vessels in the form of intermodal freight trailers and mixed cargo trailers." Not all trailers are created the same. This wasn't a lightly built over the road van trailer this was a refrigerated steel container designed to go on trains and ships so not only is it nearly airtight but it's very strong and resistant to fire. The chief probably failed to recognize this and consider that inside could be an oxygen depleted environment. Your average over the road trailer has a fiberglass ceiling and very thin aluminum walls and with that much flame at the front would be open to atmosphere by now, but not this trailer. The report also says it was carrying frozen chicken which doesn't sound flammable until you think about the amount of heat that was on the front of the trailer the chickens at the front were probably frying and filling the inside of the trailer with vaporized oil and a lot of steam so you had something like a BLEVE when the door was open. BLEVE Boiling Liquid Expanding Vapor Explosion. |

Re: Backdraft of Semi Trailer Kills Battalion Fire Chief
This is a very sophomoric mistake. NEVER expose the fire to that much of an oxygen supply ESPECIALLY if you don't know what the manifest is. This should be on a training video for all firefighters and hazardous responders

Re: Backdraft of Semi Trailer Kills Battalion Fire Chief
If you would have read the supplied report before posting, you would have read that the contents was listed as, "frozen chicken" and that was a large contributing factor. The second, was, the trailer type was not common for a refer, it's construction was basically an insulated Connex container. A very deadly combination in this exact scenario... |
