While supporting the concept that exposure to chemical agents should be kept as low as practicable, Safe Work Australia also recognises that, in practice, guidance in the form of exposure standards may be used by occupational health and safety practitioners, employers and employees or their representatives, and regulatory agencies to assist them in ensuring that workers are adequately protected from substances that may impair health or cause undue annoyance.
The exposure standards represent airborne concentrations of individual chemical substances which, according to current knowledge, should neither impair the health of nor cause undue discomfort to nearly all workers.
The exposure standards serve as guides only, and have no legal status unless they are specifically incorporated into Commonwealth, State or Territory legislation.
Exposure standards may be accessed through the Hazardous Substances Information System (HSIS).
