>>With all these discussions on how to protect our skin when we handle these
chemicals what about our lungs. Is the average organic respirator and a well
ventilated shop good enough?<<

Claudio;

If you feel that you need a respirator, it needs to be one that is rated for
chlorinated solvents.  I very much doubt that you would ever reach the ppm
threshold in your shop that you would need one; unless you spilt a large
quantity on the floor etc.

Here is the current OSHA limits for plants with employees re
levels:http://www.sspc.org/site/regnews/aboutmc.html

~EXPOSURE LIMITS: The standard requires that no employee be exposed in
excess of the PEL of 25 ppm as an 8-hour TWA or a short-term exposure limit
(STEL) in excess of 125 ppm during a sampling period of 15 minutes. The
action level for MC is 12.5 ppm calculated as an 8-hour TWA.~
