Thanks for the heads up and the link Neal.
AWS's Safety and Health Fact Sheet No. 4 (10/03) discusses this...albeit generically. What caught my eye is that OSHA's proposed revised rule will drastically reduce the PEL. From 52 mg/m3 to 1 mg/m3. That is quite a reduction when considering the general industry standard PEL in 2002 was 100 mg/m3.
It is interesting to note why OSHA is proposing this revision. They explain it at this link. It is the only item under "Hot Topics" at the bottom of the page.
