I wanted to share this article with you all. This is very Sad!

Can you guys educate us on what could have been the source of the spark? How can this be prevented? Pretty scary scenario.
 
Nothing been said but sounds like someone was transferring lacquer thinner from on drum to another.

My guess is.
Main drum was not grounded.
Funnel was plastic instead of a hazardous type that can be grounded or an anti-stat..
Of course it could have been as simple as he dropped a screw driver on the cement and it sparked.
 
Once in a while someone pumping gas will experience a condition where the body has built up static and is insulated by shoes, when the pump handle is touched, the spark ignites the fumes. Grounding oneself prior and during the handling of flammable liquids is important, as well as grounding of the containers. It's one of those freak things.
 
I read a few years back something like 45 or so fires are started a year by people pumping gas and get back in car to wait and then when they get out if they don't touch the car first to ground they get a shock when they grab the gas pump and boom. (mostly women get back in car they said)
 
So what is the proper and safe procedure for removing lacquer thinner from a five gallon bucket to a small container for cleaning paint guns?
 
i keep my thinner on the exhaust bench in the booth. the fan pulls any fumes out when i pour into a gal can .
 
When I worked as a Millwright at Kaiser Aluminum there was a paint coating line which rolled paint onto the metal as it moved from coil thru paint rolls then into baking furnace.
The thinner was MEK.
The paint room required use of beryllium hand tools and much caution when handling parts.
Air powered barrel pumps were used to transfer paint into the application feed pan.
The barrels each had a bolt type clamp fastened to the top rim and then a copper cable was connected at a certified static ground point.(which according to the electricians is not the same as any old earth ground).
The hoses used for the transfer all had a wire shield in them, mush the same as hydraulic hose.
There was state of the art ventilation in place also. The fumes from the coating room and the bake furnace were spent through duct work to a large afterburner.

What I learned from working in that situation is a solid connection static ground, grounded hoses ,ventilation and safe work practices are all needed to avoid a catastrophe.
Pouring from a 5 gallon can into a 1 gallon can I use 2 c clamps with a 12g stranded wire connected between and place a clamp on each can. Transfer should not be done any possible ignition sources such as gas appliances, grinders, welders, etc.

I imagine Barry is well versed in proper grounding and transfer techniques of low flash point materials.

edit: fluids being transferred through plastic can generate static electricity, gaseous or fluid both can be causes.
 
Really interested in what kind of hand pump might be available. As far as a ground for grounding thinner cans or grounding sheetmetal in the paint booth during the paint application process:


Is it common practice to install an electrical ground rod 6 feet deep similar to the ground used in an electrical service panel? What exactly is being used for the source of a ground in a paint booth?

Shine do you just tip up the five gallon can and pour into a gallon can or do you use some type of pump?

I got mine from my local paint supplier.

Curt, do you have a make and model number or any information I can use to track one down? So far, my search has led me to non solvent options for unerr $50 or solvent options over $200. Does your pump have grounding jumper cables to ground the cans?
 
If I can ever get a link to one to post I will but for some reason it ain't cooperating. I don't know about the safety of it and sparking or fire. Guess that's my bad for not thinking about it being a safety issue. I was just looking for a easier way to get it out of the 5 gallon can, I'm not but 5' tall so the can ain't much shorter.
 
I don't think the link worked but go to their web site and type in 5 gallon paint thinner pump and it should come up. I use one similar. Don't know if this is a dangerous way to do it but it's what every shop around here uses but that don't mean it's safe. I pump it into a small squirt bottle or a quart plastic cup.
 
I did see those, some have bonding or ground straps that are supposed to neutralize the static electricity. I may be way out in left field, and I may be making a lot out of nothing. Thats why I brought this old thread back up. Just would like everyone to think about it and make sure no one becomes a headline in the newpaper like that guy in Missoula. I actually remember that happening. Missoula is only 100 miles from where I live. Thanks for the link, I will look into it.
 
So are those safe? If not what is the proper way? If I tried to pour out of a 5 gallon can I wouldn't get any in what I was pouring in. I really would like to know to be safe. If they aren't safe then every shop I know of around here either don't know it's not or don't know any better.
 
I honestly dont know, Im just trying to find out myself. From what I understand, static electricity incidents and fumes are rare. But the do and can happen. When you consider that with the fact they sell solvent pumps for transfering solvent from one container to another and some pumps include "grounding or bonding" straps to ground both containers, Im assuming I do not know all I need to know to be safe.
 
Thanks I will ask around and see if I can find something out. I would hate to be adding to it, a lot of painting is already dangerous enough. My father use to paint synthetic enamel while smoking and clean the gun with gas without wearing nothing but a dust mask sometimes. I wear a full face mask and a paint suit. Somepeople don't care and some just don't know any better. I learn something new all the time.
