Note
The National Code of Practice for Control of Workplace Hazardous Substances [NOHSC:2007 (1994)] lists, in priority order, the hierarchy of control measures for use in carrying out risk control. Guidance on exposure standards can be found in the Exposure Standards for Atmospheric Contaminants in the Occupational Environment [NOHSC:1003 (1995)].

(1)

An operator must ensure that no employee or contractor at work is exposed to an airborne concentration (measured over the length of time relevant to an exposure standard) of a hazardous substance, in the breathing zone of the employee or contractor, at a level that exceeds the exposure standard.

Penalty:
10 penalty units.

(2) An operator must ensure, on the basis of a risk assessment carried out under regulation 2.15, that exposure to a hazardous substance is:

(a)

prevented; or

(b) if it is not reasonably practicable to prevent the exposure — adequately controlled in order to minimise the risks to health caused by the substance.

Penalty:
10 penalty units.

(3)

An operator must take all reasonably practicable steps to prevent or control exposure to a hazardous substance by measures other than the provision of personal protective equipment.

Penalty:
10 penalty units.

(4)

If measures undertaken in accordance with subregulation (3) do not prevent, or provide adequate control of, exposure of an employee or a contractor to a hazardous substance, the operator must, in addition to taking the measures, make available to the employee or contractor suitable personal protective equipment that will adequately control the employee's or contractor's exposure to the hazardous substance.

Penalty:
10 penalty units.

(5)

An operator must ensure that engineering controls, safe work practices and personal protective equipment that are used to prevent or control exposure to a hazardous substance are properly maintained and used.

Penalty:
10 penalty units.
