If you are a person conducting a business or undertaking (PCBU) who has workers (including yourself) that work with silica or silica containing products this guide is for you. Silica containing products include:
- manufactured solid stone products such as engineered (composite) stone benchtops
- cement, mortar and grout
- concrete, concrete blocks and fibre cement products
- drywall and some plasterboards, and
- pavers and tiles including roof tiles.
This guide explains what you must do to keep your workers safe from the risks of respirable crystalline silica (silica dust).
Everything in this guide is covered by the model Work Health and Safety (WHS) laws.
The workplace exposure standard (WES) for respirable crystalline silica was changed to an eight hour time weighted average (TWA) of 0.05 mg/m3 in December 2019. This new WES does not have effect in a state or territory until it is implemented by that jurisdiction. Visit the Workplace exposure standards for airborne contaminants webpage for implementation dates for your state or territory.
