Is cutting tiles, concrete or stone dangerous?

The short answer

Cutting, grinding or drilling concrete, brick, tile and engineered stone releases respirable crystalline silica, which causes irreversible lung disease. Water suppression or on-tool extraction and proper respiratory protection are required, not optional.

Checked against 4 published sources, listed in full at the end of this page. How we source this

Silica is a natural component of most masonry materials. Cutting them dry produces particles small enough to reach deep into the lung and stay there, and the resulting scarring is permanent and progressive. Australia has seen a resurgence of silicosis serious enough that engineered stone benchtop fabrication was banned nationally.

The controls, in order of effectiveness

  1. Do not create the dust. Buy materials cut to size, or use a method that does not generate fine dust.
  2. Water suppression. A wet cut traps the dust at the source and is dramatically more effective than anything downstream of it.
  3. On-tool extraction with an appropriately rated vacuum, for situations where water is not practical.
  4. Respiratory protection, correctly fitted, as the last layer rather than the first.

What does not work

  • A disposable nuisance dust mask, which is not rated for respirable particles and does not seal.
  • A household or workshop vacuum, which passes fine particles straight through and disperses them.
  • Working outdoors, which helps but does not protect the person standing over the cut.
  • Sweeping up afterwards, which re-suspends everything that settled.
