Ultrasonic Injector Cleaning

[Craig Moates]

True, true on the glue sniffers. However, I'm not sure if toluene kills
brains through any route other than O2 starvation. CO is one of the most
efficient in this capacity (I know we've all been a little guilty of
exposing ourselves and others to at least trace levels at some point during
tuning!).

I know there are some really nasty chemicals out there, like benzene, which
have been conclusively proven to cause cancer (leukemia), and others that
can have a variety of side effects (testicular shrinkage for chlorocarbons,
instant death for sulfides and intermediates like phosgene). It may be worth
mentioning that some isomers of xylene are particularly nasty. Look on the
web for 'MSDS material safety data sheets' for any proposed chemical with
which you plan to work, some of the dangers may scare you. They should.

Conclusively, there's no substitute for fresh air when it comes to the human
body. If you're going to experiment with solvents - even gasoline - by all
means, please take measures to ensure minimization of exposure to the vapors
or skin contact with the liquids. An exhaust vent or open cross-ventilation
(stay upwind) is really a must.
