Rob,  Essentially, this is what the German MAKs do with carcinogens.  They son't set standards and employers must use the best technology available to keep exposure as close to zero as possible.

So it is really interesting to read the prerule and comment periods for OSHA PELs on carcinogens where a combination of governmental and industrial "experts" argue over how many workers it will be acceptable to kill.

I sense the toxicologists on the list getting all atingle here.  Prepare for an avalanche of replies!  I'll leave the details of why the two organizations came up with different numbers to others (short answer - different methods, different studies, different criteria etc.)


The best choice from any perspective is 0 ppm, and after that ALARA - As Low As Reasonably Achievable.  See http://www.ilpi.com/msds/ref/alara.html and the references therein for more on the ALARA concept.
