An electric arc that burns brake parts cleaner (just the residue on metal cleaned with it is enough) produces phosgene gas, one of the most toxic poison gases used in WWI. Supposedly, a single whiff of it is enough to do irreversible damage to a person's kidneys and liver. Just because I think that the danger of zinc fumes is commonly exaggerated, that doesn't mean I don't believe anything is dangerous.

The chemical that produces phosgene gas is carbon tetrachloride and that is when its burned . Thats the reason why you can't buy or refill a carbon tetrachloride fire extinguisher. Carbon tetrachloride will neutralize gasoline. My dad used it when repairing gas tanks. He would drain gas tank and shoot tank with carbon tetrachloride and than welded or brazed tank. He always did it outside and on a day with a go breeze to carry fumes away.

I don't know if phosgene gas comes from carbon tet or not but I know it comes from dry cleaning fuid called perk (perchol someting or other). I used Brakleen to clean aluminum before mig welding until they took the perk out of it. Took a lot of label reading before I could find it again in another product.
