mask, gloves and goggles

Personal protective equipment

At the very least use a mask, gloves and goggles.

You should also cover any recent cuts or abrasions that are likely to be exposed to treated timber or treated timber sawdust.


Chemicals used to treat timber may leach out of the timber to the surface of the wood. To avoid skin contact wear gloves at all times.

  • Gloves must be strong enough to resist tearing, and should be cleaned or disposed of after working with treated timber. 
  • Gloves will also protect you from painful treated timber splinter injuries.

Dust mask

Avoid breathing in sawdust from all timbers, whether or not they have been treated.

  • If cutting, drilling or planing LOSP treated timbers, special care should be taken because the temperature of the cutting face (the point where the cutting blade and wood meet) can be high enough to give off chemical fumes.
  • Wear dust (P1) or dust and fume (P2 or N95) rated masks. Cheap paper masks are not suitable for working with treated timber.
  • If you are unsure about which mask to use, ask at your local hardware store.


All timber sawdust and fragments, especially treated timber sawdust and fragments, should be kept out of the eyes.

  • Always wear goggles when cutting treated timber.
