You should use this guide if you are a person conducting a business or undertaking (PCBU) who has workers (including yourself) that work with silica or silica containing products, except if you are working with engineered stone.

This guide will help you, as a PCBU to understand the risks from silica dust and make decisions about protecting your workers from exposure to silica dust when working with products other than engineered stone.

This Guide includes references to the legal requirements under the WHS Act and WHS Regulations.

Silica containing products covered in this guide include:

• natural stone products such as marble or granite benchtops
• asphalt
• cement, mortar and grout
• concrete, concrete blocks and fibre cement products
• bricks, and
• pavers and tiles including roof tiles.

Detailed information on eliminating and minimising the risks of silica dust exposure from the processing of engineered stone can be found in the model Code of Practice: Managing the risks of respirable crystalline silica from engineered stone in the workplace.
