Engineered stone prohibition to commence 1 July 2024

A prohibition on the use, supply and manufacturing of all engineered stone will commence on 1 July 2024 in NSW.

What is engineered stone?

Engineered stone is defined as an artificial product that:

  • contains crystalline silica
  • Is created by combining natural stone materials with other chemical constituents such as water, resins, or pigments
  • undergoes a process to become hardened.

The ban does not apply to other silica related materials such as:

  • concrete and cement products
  • bricks, pavers and other similar blocks
  • porcelain products
  • ceramic wall and floor tiles
  • roof tiles
  • grout, mortar and render
  • plasterboard.

Why is the ban necessary?

  • Rates of silicosis and silica-related diseases in Australian workers have risen substantially in recent years, with a disproportionate number of diagnoses in engineered stone workers.
  • When engineered stone is processed, the dust generated has different physical and chemical properties that likely contribute to more rapid and severe disease.
  • There is no scientific evidence for a safe threshold of crystalline silica content in engineered stone, or that lower silica content engineered stone is safer to work with.

Reminder: In the lead up to the ban, for tasks where engineered stone is used:

  • employers continue to have a legal duty to protect workers by managing the health and safety risks from silica dust
  • workers also continue to have a legal duty to take reasonable care of their own, and others, health and safety at work.
