41 Ensuring exposure standards for dust and diesel particulate matter and carbon dioxide not exceeded

(1) The operator of a mine or petroleum site must—

(a) as far as reasonably practicable, minimise the exposure of persons at the mine or petroleum site to dust and diesel particulate matter, and

(b) ensure no person at the mine or petroleum site is exposed to 8-hour time-weighted average atmospheric concentrations of airborne dust and diesel particulate matter that is more than—

(i) for respirable dust—3mg per cubic metre of air, or for a coal mine, 1.5mg per cubic metre of air, or

(ii) for inhalable dust—10mg per cubic metre of air, or

(iii) for diesel particulate matter—0.1mg per cubic metre, measured as sub-micron elemental carbon.

Maximum penalty—

(a) for an individual—60 penalty units, or

(b) for a body corporate—300 penalty units.

(2) Without limiting subsection (1), the operator of an underground coal mine must—

(a) as far as reasonably practicable, minimise the exposure of persons to carbon dioxide in the mine, and

(b) must ensure no person in the mine is exposed to an 8-hour time-weighted average atmospheric concentration of carbon dioxide that is more than—

(i) for short term exposure limits—30,000 parts per million, or

(ii) otherwise—12,500 parts per million.

Maximum penalty—

(a) for an individual—60 penalty units, or

(b) for a body corporate—300 penalty units.

(3) The Workplace Exposure Standards for Airborne Contaminants apply in relation to a concentration referred to in subsection (1) or (2) as if the concentration were an exposure standard referred to in the document.

(4) In this section—

8-hour time-weighted average has the same meaning as in the Workplace Exposure Standards for Airborne Contaminants.

short term exposure limit has the same meaning as in the Workplace Exposure Standards for Airborne Contaminants.
