Degreasing brakes

[jansens]

Hi Chris, no problem! And you're right to question things, this one seemed like a scare story to me too when I first read about it. But it is well documented (in trustworthy places) that phosgene gas can be produced from welding things cleaned with chlorinated brake cleaners. And the MSD Sheets do specifically mention phosgene as a hazard. Whether or not anyone has ever died from it I haven't been able to find out. But then again you're not likely to hear about the people who get sick from it and don't die unless you know them personally.

But it's like a lot of things, say welding petrol tanks or spraying two pack isocyanate paints at home without full protective gear. Sure, you can probably get away with it but you should at least be aware of the dangers before you try.
