Decontaminate and get a clearance certificate

You must ensure there are facilities to decontaminate your work area, and any equipment or people involved in the work (or who accessed the area).

All contaminated material and equipment must be sealed, labelled properly, and disposed of at an authorised waste facility.

If you can’t dispose of contaminated clothing, keep it in a sealed container till it’s re-used for asbestos removal purposes. Or, better still, send it to a laundry that is equipped to clean asbestos-contaminated clothing.

Get a clearance certificate

If you hold an asbestos removal licence and have finished removing asbestos from residential premises, you must arrange for an independent licensed asbestos assessor (or independent competent person) to conduct a visual inspection and, if necessary, air monitoring.

Once satisfied that the area is free of visible asbestos contamination and air monitoring shows asbestos below 0.01 fibres/ml (if required), the assessor (or competent person) will issue you a clearance certificate.

Air monitoring must use the membrane filter method and be carried out before, during and, if necessary, after your removal work.

If you hold a Class A licence and are removing asbestos from a workplace, the person who commissions you must arrange for the assessor (or competent person).

If monitoring in the workplace shows asbestos between 0.01 and 0.02 fibres/ml, you must:

  • investigate the cause
  • implement controls to prevent exposure
  • prevent further release of fibres.

If monitoring shows asbestos to be over 0.02 fibres/ml, you must:

  • stop work
  • notify us
  • investigate the cause
  • implement controls to prevent exposure
  • prevent further release of fibres.
