I apologize for piling on, but I want to add one more piece of information
to your understanding of OSHA standard 29 CFR 1910.1000. The 400 or so
chemicals on the PEL list were NOT selected on the basis of risk. If they
have anything in common, it's that those chemicals had high sales volumes in
the fifties and sixties when the list was compiled. 

A few low volume / high risk chemicals, like diborane, are on the list. More
of the list is devoted to high-volume, low-risk chemicals, like calcium

Stay healthy,
