[Tigers] Brake Cleaner Danger

[Sandy Ganz]

Just checking stock (some old) Brake and Carb cleaners and they are all
Chlorinated chemials free. So can I spray parts and heat up with a torch and
not die? I'm guessing it was the chlorinated stuff that was the real problem
not that the other petrolum distillates are safer but seems to be less of a
problem these days.

Mustard Gas is not Phosgene.  Check out the Wikipedia entry
for discussion.

Where phosgene is found and how it is used
Phosgene
was used extensively during World War I as a choking (pulmonary) agent. Among
the chemicals used in the war, phosgene was responsible for the large majority
of deaths.
Phosgene is not found naturally in the environment.
Phosgene is
used in industry to produce many other chemicals such as pesticides.
Phosgene
can be formed when chlorinated hydrocarbon compounds are exposed to high
temperatures. Chlorinated hydrocarbon compounds are substances sometimes used
or created in industry that contain the elements chlorine, hydrogen, and
carbon.
The vapors of chlorinated solvents exposed to high temperatures have
been known to produce phosgene. Chlorinated solvents are chlorine-containing
chemicals that are typically used in industrial processes to dissolve or clean
other materials, such as in paint stripping, metal cleaning, and dry cleaning.
Phosgene gas is heavier than air, so it would be more likely found in
low-lying areas.



CDC Info. Phosgene was a component added to mustard gas
during WW1. Because it was heavier than air it made the deliery of the weapon
much more deadly and effective. The bulletin we recieved from the State of Ca.
years ago indicated that the flame method of detecting freon leaks produced
Phosgene, a component used in mustard gas.

I do stand corrected for not
making clear the relationship of phosgene to mustard gas. Thanks for pointing
that out.
