Airborne dusts and particles can present a risk to the health and safety of employees and others in the workplace. Generally, exposure to any concentration of respirable dust should be avoided whilst some forms of dust (eg: asbestos and silica) are recognised carcinogens. The dust hazard should be controlled through the implementation of a risk management program which includes identifying the hazard, assessing the risk and implementing the appropriate control strategy. Where a dust hazard has been identified and cannot be eliminated from the workplace, then a hazard monitoring and health surveillance program needs to be implemented. Tasmanian Workplace Health and Safety Regulations 1998 17,18,19 provide guidance on the hazard identification, risk assessment and control requirements. The hazard monitoring and health surveillance requirements are at Regulations 21 and 22 respectively. Dust exposure standards can be found at: ASCC (Formerly NOHSC)
