air supply system occurs, workers should leave the asbestos removal work area using normal decontamination procedures; the use of a back-up belt-mounted filter device allows for adequate respiratory protection during this process.
If the number of workers wearing air-line respirators inside an enclosure is likely to result in the tangling of air lines, manifolds should be provided to minimise this tangling and assist workers in moving around the enclosure.
The capacity of the compressor should be adequate for the number of air-lines, and the location
of the compressor's air intake should be assessed to ensure appropriate air quality and avoid contamination. Air from a compressor must be filtered before supply to a respirator.

4.6 Decontamination
Decontamination for the work area, workers, PPE and tools used in asbestos removal work is an important process in eliminating or minimising exposure to airborne asbestos fibres, particularly to persons outside the asbestos removal work area.
To determine the appropriate decontamination procedure, the risks of each individual asbestos removal job should be assessed.

Decontamination of the removal work area
There are two types of decontamination processes:
    * Wet decontamination, or wet wiping, involves the use of damp rags to wipe down contaminated areas. Rags should only be used once, although they may be refolded to expose a clean surface. The rags should be used flat and should not be wadded. If a bucket of water is used, the rags should not be re-wetted in the bucket as this will contaminate the water. If the water
      is contaminated, it must be treated as asbestos waste. Care should be taken to avoid any potential electrical hazards when using this procedure.
    * Dry decontamination involves carefully rolling or folding up and sealing plastic sheeting and/or vacuuming the asbestos removal area with an asbestos vacuum cleaner. Dry decontamination should only be used where the wet method is not suitable or poses a risk because of other hazards such as electricity or slipping.
Contaminated items, tools, equipment and clothing must not be removed from the removal work area unless they have been decontaminated or contained.
If an item is not able to be decontaminated, or is not suitable for decontamination, it should be placed in a sealed container and disposed of in accordance with the WHS Regulations. The sealed container must be decontaminated before it is removed from the asbestos removal work area.
If asbestos removal work involves friable asbestos, the decontamination procedures must include decontamination units. Glove bag and wrap and cut methods are exceptions where personal decontamination procedures are likely to be satisfactory and units are not necessary. Mini-enclosure removals may require a combination of personal decontamination and decontamination units.

Decontamination of tools
