Update: Prohibition on the use of engineered stone

On March 22, 2024, ministers responsible for Workplace Health and Safety (WHS) convened to discuss proposed revisions to the model WHS Regulations aimed at implementing a ban on engineered stone.

The ministers collectively determined that the ban would encompass engineered stone benchtops, panels, and slabs. Engineered stone, as defined in the model WHS Regulations, refers to an artificial product meeting the following criteria:

• Contains a minimum of 1% crystalline silica by weight
• Formed by combining natural stone materials with additional chemical components (e.g., water, resins, pigments)
• Undergoes a hardening process

Exceptions to this definition include:

• Concrete and cement-based products
• Bricks, pavers, and similar construction blocks
• Ceramic wall and floor tiles
• Sintered stone
• Porcelain products
• Roof tiles
• Grout, mortar, render
• Plasterboard

Furthermore, ministers clarified that finished engineered stone items, such as jewellery, garden ornaments, sculptures, and kitchen sinks, which do not necessitate further processing or alteration, would be exempt from the ban.

Regarding transitional arrangements, ministers agreed that activities involving the supply, installation, or processing of engineered stone benchtops, panels, and slabs between July 1, 2024, and December 31, 2024, would be exempt from the prohibition if performed under a contract executed on or before December 31, 2023.
