Unlike the United States which has a strong federal government and relatively weak states, in Australia the opposite is true. The provinces are considered co-sovereign states with the federal government; and the territories though under the egis of the federal government, also promulgate their own laws. However, all the six states and several territories collaborated through an organization called Safe Work Australia to develop a common set of OELs and a model occupational statute and associated regulations that the states and territories can adopt.
Occupational Exposure Limits
Australia US-OSHA ACGIH TLV
Ethylene Oxide 1 ppm (8 hr TWA) 1 ppm (8 hr TWA) 1 ppm (8 hr TWA)
Glutaraldehyde 0.1 ppm peak n/a 0.05 ppm ceiling
Hydrogen peroxide 1 ppm (8 hr TWA) 1 ppm (8 hr TWA) 1 ppm (8 hr TWA)
Ozone 0.1 ppm 0.1 ppm (8 hr TWA) 0.05 - 0.2 ppm
1) TWA = time weighted average, peak = ceiling = maximum permissible exposure at any time.
2) Regulations are always subject to change and to the readers should verify that the above information is correct before relying on this information.
Work Safe has also developed a guide on the application of workplace exposure standards for airborne contaminants (exposure standards) in the workplace.
Occupational Safety Statutes and Regulations
The federal government and all of the states and territories, except for Victoria, have adopted the model statute and regulations. As with most common law countries, the legislature passes a broad act or statute that empowers a government agency to then develop more specific regulations. The statutes and regulations are listed below as a reference but will not discussed further in this article.
Work Health and Safety Act 2011
Model Work Health and Safety Regulations 2011
While Victoria's statute is different from the other states, its occupational laws are generally compatible.
The Victoria Occupational Safety and Health Act of 2004
The Victoria - Occupational Health and Safety Regulations 2007
