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
  • asphalt
  • cement, mortar and grout
  • concrete, concrete blocks and fibre cement products
  • brick
  • 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.

How to use this guide

This guide will help you to understand and make decisions about protecting your workers from exposure to silica dust. It provides general information about controlling the risks of working with silica. It also provides more detailed information about controlling the risks of working with silica containing products that may contain very high levels of silica and pose a significant risk to the health of your workers.

We use ‘must’, ‘requires’ or ‘mandatory’ where duty holders have a legal obligation to comply with a requirement.

We use ‘should’ to recommend an action and ‘may’ where you can choose to do as we recommend.

More information

More information about controlling silica dust at your workplace is available from your local WHS regulator.
