deadbodyman although its never happend to me it concerns me. Electrical switches should be mounted on the,if it does happen you wont be in there.My luck I'd have a date that night and loose all my hair eye brows mustashe and she would run before I got her drunk.(Ihate that)I'm no good at gambling.... a one in a million chance is not enough for me... so when shes not looking I tie her shoe laces together just in case she tries to get away

Rob Keller Not to make any one think of doing anything but the safest approach .

But Deadbodyman. everything has to be Just right for it to go boom.

Too much fuel or O2 & nothing will happen.

Just like in a motor . if it floods it wont run.

I had a arse hole drop out a fuel tank & flip it dumping a few gallons on the ground while I was cutting a exhaust pipe with a torch.

I was suited up & felt it getting warm while people were yelling @ me to not blow slag into the fuel.

Well it went POOF & went out because it ran out of O2 inside the building.

If that would have happen closer to the door it would have been very bad.

deadbodyman I beg to differ ding , If a little thing like a fart can cause so much grief just imagine what a full scale booth explosion can do. SERIOUSLY,I was thinking about ...WHY...a fire could start in a booth...."smoking" ? nobody's stupid enough to do that.....Then it hit me, electrical switches in a homemade booth......a spark from the switch could ignite the fumes or even a fan motor swiching on....So make sure to have your switches outside the booth and although I've done it ..using portable box fans concerns me now, paint booth fans have explosive proof motors , so be careful and do your home work when making a booth or painting in your home's garage, someones life may depend on you

Ha, saw a whole building full of paint burn, blow up and burn for hours once ignited. First was a very loud bang, and we just thought it was another accident at the intersection nearby. Nope, it was the initial explosion in a building full of paint and other flammables. Once it was going, not even the firemen were getting close. You could feel the heat from like 300' away. If you want to see just how fast something ignites in an enclosed space, like a garage or house, get yourself an EMPTY 3' x 3' x 3' box and place it in a wide open area away from anything combustible. Loosely ball up some paper to about 1/4 full and wet some with gasoline or laquer thinner - a small amount is all that is necessary, like a few ounces. Toss it into the box and stand back while you get the nerve to strike a match and fling it towards the box. When you get one near enough, the thing will make a giant fireball, suck the sides of the box in and blow 'em back out. It's quite the scene and exactly what will happen to any room or garage you are in. You get the picture.

This is just one ive seen a while back when planning to build a paint booth,there is more thats been presented to us in safety classes and training on jobs that we are required to paint the fabricated steel in fab shops..i'll find them later and post...
Im a union ironworker and about every job we go on is required mandatory safety training on the type of job we are doing and the safety guys always have first hand vids/examples of the dangers to show us..
The danger is DEFINITLY there,not a myth..

All it takes is 1 unsuspecting right conditions and it happens at the blink of an eye.
I have to agree that alot of explosions/fires are not advertised in the media if it can be prevented because of lawsuites and denied insurance claims

dinger The only thing I have seen like this is when I wrked (briefly) building waterbed frames from wood. The small paint booth we used was full of 2x12 boards, frshly stained and cleared with lacquer. The painter was standing outside the door, lit a cigarette, we hear a whoosh, looked inside where the boards were laid out, they had a flame hovering above the boards. We used the extinguisher and made a mess, powder type, got a real good butt chewing, but with the booth made of wood, it could have been much worse.

4 Jaw Chuck I once painted a car in -5C weather in a garage with no ventilation with a 55 gallon barrel stove in it, I used Acrylic Urethane mixed 50/50 with hardener. It was so cold my compressor water separator kept freezing up and I had to eventually remove it to continue, the fog created by the gun was so thick I had to hold my breath in between shots because the mask kept getting clogged. I made 12 coats in 12 hours and it took an ounce of fisheye remover in each mixed gallon to keep the paint from "eyeing". I had stoked the stove to try and get it warm but once I started painting I just let it go out.

There was never an explosion but I was very worried about it at the time, the paint took a week to flash to the point where it was dry enough to touch and the car looked like it had been dipped, truly spectacular!

I would never do it again because of the serious danger of explosion but the weather turned bad in two days before I could shoot the car and my father and law was adamant it be painted NOW!

I learned some things that day, painting when its cold out is a PITA but it sure levels out nice.

Second, in the late '80's a former co-worker was going to get into the fiberglass body business. He bought a nice chopper gun setup, had his molds made, etc. His story was that it was a cold day, so he was using some extra hardener to help the glass set up quicker. As he was cleaning the equipment with acetone, the hot resin started a fire, and he was luck to excape with his life.

Fiberglass will catch on fire if you lay it on too thick with a lot of catlyst. The reaction creates heat and if you layer it on really thick it will go up in flames. Someone I know almost set their work on fire. He said the best he could do was pour water over it after it started smoking.

I second the mythbusters. I have my doubts on how easy it is to get a perfectly concentrated mixture in an area large enough to be combustible. Like you I have never heard of any stories of explosions with car painting.

Chris Kemp This a good one!

I was about seventeen years old and I was working for an older guy that had a little body and paint shop. He did as much insurance work as he could get but he also did a lot of used car work. He had a special that he did for the whole sale car guys that he called a dip job. What it consisted of was me washing the car with comet and then sanding and repairing any small dents that it had and not sanding the rest of the car. I would tape the car up and he would paint it with the cheapest car paint he could buy. At that time it was ZacLac synthetic (this was 1973). Because he was real good with a paint gun when the car was finished it really looked good and all of the used cars guys loved the dip jobs. In the winter time he would not use thinner he would set the gallon can on a hot plate and that would reduce the viscosity. Now in the summer time it was a different story. Believe it or not on these dip jobs he would use gasoline for thinner. It really made the cars shine good. Well the compressor was small, the booth (if you want to call it that) had poor ventilation and the shop was real small too and because of all of this I had to stop work when ever he painted. He kept the compressor in the paint booth off to one side and it had been acting up when it kicked on. During the time that he would paint I would usually walk to the corner store and get me some crackers and a cold drink. I'd then come back and sit across the street under a big oak tree and wait for him to finish. On that particular day he came out between coats and sat there with me for a few minutes. While we were setting there shooting the breeze we heard the compressor try to kick on and it made its usual humming sound for a second and then the whole booth blew up and went up in flames. Nobody was hurt but it caught the whole shop on fire and put him out of business.

A lot of the make shift booths that I see up here on this web site look similar to the one that he had. Proper ventilation and using the right material has been a must for me ever since. Make sure to keep the vapor away from any source of ignition.
