Exposure Limits: Australia

The National Occupational Health and Safety Commission (NOHSC) is responsible for recommending workplace exposure standards, as well as attending to other health and environmental matters, including those that may pertain to nickel. Historically, the NOHSC exposure recommendations have corresponded to the American Conference of Governmental Industrial Hygienists’ (ACGIH) Threshold Limit Values (TLVs) (see Section 7.1.5). As such, the current workplace exposure recommendations of the NOHSC are 1.0 mg Ni/m3 for metallic and water-insoluble forms of inorganic nickel and 0.1 mg Ni/m3 for water-soluble nickel forms. The recommendation for nickel carbonyl is 0.12 mg Ni/m3.

While the NOHSC can recommend exposure limits, it is the individual State Governments which have responsibility for actually setting and implementing standards. The State Governments usually impose standards which are in keeping with the NOHSC recommendations, but they may impose more stringent standards if deemed necessary.
