I had a garage fire in 1980 that started with a battery charger on a street bike that caught the bike on fire. We were out front of the house when we saw smoke billowing out of the back work shop area.
I called 911 and reported it, just as the phone died from melted wires.
I ran into the front part of the garage and got out 1 street bike and started back in, when something blew up and blew me back 10 feet.. Singed eyebrows, eyelashes and bangs..
My motorhome and enclosed bike trailer was in front of the garage about 6 feet away. It melted the aluminum off the back door and caught the trailer on fire. I knew a 5 gal can of gas was inside the trailer, I pulled it out into the street and I used up the Motorhome fire ext., a fire ext from the house and one from my truck to finally get the trailer out.
The FD is only 3 blocks from our house and it only took them about 5-6 minutes to get there. But they ran a hose up to the garage, charged it, then left it lay on the ground... So I picked it up and started fighting the fire myself for several minutes. Then a Fireman took back over.
There were bikes inside that looked like giant roaring candles, with pressurized gas coming out of the tanks shooting flames like a flame thrower 6 feet in the air. 8 Bikes.. Small explosions kept going off from paint cans, lubes and cleaners.
I had a set of torchs/tanks in there and told the FD about them, and he said they wouldnt blow up, but would release the oxy/Fuel and add to the fire.
It was a VErY HOT fire. It melted the siding off the neighbors house, Took paint off our house 20 some feet away, Melted the plexi-glass storm windows right out of the frames of the house..
Flames came out the front of the 16 foot overhead door that was open and the side windows..
The whole garage was sheetrocked, walls and ceilings.. Everything inside it was destroyed.... The garage itself, I saved all but the front 3 foot. We chainsawd off the whole front 3 foot. Built a new front and new 16 foot over head door (1 foot taller), new windows, Siding over the windows and re-sheet rocked the whole garage again.
Insurance only paid 10% of what my house was worth for the Garage. I had a oversized 2.5 built onto the original 1.5 car garage. so was wayyy underinsured for the garage.
Contents, they pay 50% of what your house is insured for, But believe me, they wouldnt cover half the stuff in there.. I fought the adjuster for weeks as they wanted me to settle for peanuts. After threatening to get a lawyer, they finally agreed to pay me the amount I was supposed to get.
Sheet rock or metal or anything fireproof is definately worth having in a workshop/polebarn/garage if you want to save it.. The contents..?
Thats a whole nuther story..
