Managing the risks of respirable crystalline silica from engineered stone in the workplace: Code of practice

Engineered stone ban


From 1 July 2024 the use, supply and manufacture of engineered stone slabs, panels and benchtops of engineered stone is banned in Western Australia. This Code remains available for work that is permitted under transitional arrangements until 31 December 2024.

This Code provides practical guidance on how to effectively manage risks associated with working with engineered stone and, subsequently, minimise the incidence of respirable crystalline silica related diseases, such as silicosis. 

The Code provides guidance through the lifecycle of an engineered stone product including fabrication, installation, maintenance, removal and disposal.

Working with engineered stone carries a range of risks beyond those covered in this Code, such as manual handling. Other relevant codes of practice to help manage these risks include:

  • Managing the work environment and facilities
  • Construction work
  • Hazardous manual tasks.
