Cleaning up asbestos contaminated dust or debris

The Work Health and Safety (National Uniform Legislation) Regulations contain specific obligations for a number of duty holders in relation to safely removing asbestos, including requirements for asbestos removalists to be licensed.

Asbestos-containing dust or debris (ACD) at a workplace must be cleaned up by a licensed Class A asbestos removalist unless:

  • associated with a Class B asbestos removal job
  • generated by a removal job of 10 m2 or less of non-friable asbestos
  • it is a ‘minor contamination’ not associated with asbestos removal

What is asbestos-contaminated dust or debris (ACD)?

Asbestos-contaminated dust or debris (ACD) is dust or debris that has settled within a workplace and it is, or assumed to be, contaminated with asbestos. Examples of ACD include:

  • ACD that has been accidentally dislodged from a wall or ceiling following a collision
  • ACD that accumulated over time:
    • in an asbestos-containing material (ACM) pipeline or conduit, surrounding an ACM cement flue
    • in an electrical switchboard with an ACM electrical mounting board or conduit box
    • on a horizontal surface covered by an ACM roof
    • in the metal guttering from an ACM roof

If it is reasonably practicable to remove the source of a minor contamination, this must be done. Depending on the amount of ACD and its state, removal of the source must be done by a licensed removalist (unless it is less than 10 square metres of non-friable ACM).

In other cases the risk must be minimised so far as is reasonably practicable.
