California OSHA may have additional regulations bearing on exposure to nickel carbonyl, but at the Federal OSHA level all we have are the exposure limits in 29CFR1910.1000 Table Z-1. That is set at 0.007 mg/m3 (0.001 ppm) as an 8-hour time-weighted average.

It is not particularly relevant to your question, but did you know that at one time, before legionella was identified as the cause, nickel carbonyl was seriously proposed as the cause of Legionnaires' Disease?

Subject: [DCHAS-L] Nickel Carbonyl

I have a client in California who is considering using a process that uses nickel carbonyl. I have made them aware of the extremely toxic nature of this compound. The only reason they are considering it is that it solves a problem that would be very difficult to achieve any other way. My question to the community is this: what, if any, specific regulations are there regarding the use of this compound?

Thank you
