If you are an employer in construction, manufacturing, tunnelling, demolition, mining, quarrying, or stonemasonry, you and your workers may be exposed to silica dust at work.
As an employer, you must manage the health and safety risks of silica dust at work and keep workers and others’ exposure at your workplace as low as possible.
There are rules to prohibit uncontrolled processing of engineered stone.
Managing risks
To protect yourself, your workers and others at the workplace from exposure to silica dust, you must use a risk management approach. You must identify the hazards, assess the risks, control the risks, and monitor control measures.
You have duties to:
Identify if silica dust is being produced. This can happen when products that contain crystalline silica such as stone, bricks, concrete and tiles are cut, drilled, polished or ground.
Control the risk of exposure to silica dust. If you can’t eliminate the hazard of silica dust completely, you must keep exposure as low as possible. You need to put in place a combination of control measures. For example, using wet cutting methods, on-tool dust extraction systems, local exhaust ventilation, and breathing protection.
Conduct air monitoring. You must make sure control measures are working and the workplace exposure standard for respirable crystalline silica (0.05 mg/m3 (eight-hour time weighted average)) isn’t being exceeded.
Provide health monitoring. Arrange health monitoring for workers exposed, or at risk of being exposed, to silica dust. You and your workers may also be able to access health checks and testing provided by your work health and safety regulator.
Consult. Talk to your workers and any health and safety representatives about the health and safety risks of silica dust and the control measures in place to manage the risks
Use the hierarchy of controls to work out the control measures you need to implement. In most cases, you will need to use a combination of control measures to protect workers from exposure to silica dust.
