(quoted from post at 12:16:28 03/11/16) well, casecollector. Sorry, but if there were no people in any of the cars, their sh1t can just burn to the ground while I put on my respirator to prevent breathing all the toxic fumes pouring out of the plastic and such flaming away. My lifetime of scarred lungs is not paid by the insurance company of the car owners, so f them. Now, if a kid is inside? I'd be the first one breaking the glass.
We responded to a burning generator set at work last year- CAT six cylinder fully involved. As first responder, I reported the fire and did what I could to suppress it with the available extinguishers- CO2 etc. While I was on one side, a coworker arrived and lit off a big powder-filled extinguisher from the other side. He blew the powder right through to me, and I got a face/lung full, with no breathing protection. Coulda been far worse than it was. Again, I was reminded that that generator was already trashed, and the utility can afford another one with the insurance settlement. It was not threatening anything else, just get out of the way and stay safe.
I don't know the full story of the nursing home fire you referenced, but I can imagine the place my FIL stays, way out in the country, full of oxygen tanks and bedding, would go up quickly if not protected by a water suppression system.
