What it contains

Engineered stone products such as those used as kitchen benchtops can contain up to 95% crystalline silica. When you do things like cut, grind, drill or polish products that contain crystalline silica, it releases very fine dust. Breathing in this dust is likely to cause deadly diseases, such as:

  • silicosis
  • lung cancer
  • kidney disease
  • autoimmune disease

This document tells you about employer responsibilities for controlling the risks of exposure to crystalline silica dust from engineered stone. It covers ways to control the dust, and requirements for health and air monitoring.
