consists of an injection head with numerous side holes or outlets through which the water or wetting agent is fed to the asbestos.
To facilitate more rapid wetting of the asbestos, holes or cuts should be made in the outer covering to enable the water or wetting agent to be injected in such a manner as to ensure that the asbestos is saturated but not just washed out through a liquid passage.
The soaking should be done before removal. The quantity of water or wetting agent and the time to soak will depend on the thickness of the asbestos, access to the asbestos and location of the holes.
The saturated asbestos should then be removed in sections, placed in a properly labelled container, sealed and disposed of as with the spray method.

Dry method
The dry method is not preferred as there is a much greater potential for airborne asbestos fibres to be generated. The dry removal method can only be used if the wet spray or soaking methods are not suitable, for example if there are live electrical conductors or if major electrical equipment could be permanently damaged or made dangerous by contact with water.
If the dry removal method is used, the following controls should be implemented:
    * Non-friable removal – Enclose the asbestos removal work area as far as is reasonably practicable.
    * Friable removal – Fully enclose the asbestos removal work area with plastic sheeting (a minimum 200 µm thick) and maintain at a negative pressure (at least 12 Pa water gauge). Ensure all workers involved in the removal operation wear full-face positive-pressure supplied air-line respirators.
    * Friable and non-friable removal – The asbestos should be removed in small, pre-cut sections with minimal disturbance to minimise the generation of airborne asbestos fibres as much as possible. Wherever reasonably practicable, a HEPA-fitted vacuum cleaner should be used.
    * All waste material should be immediately placed in appropriate wet containers which are wetting to suppress creation of dust and airborne fibres.

4.4 Tools and equipment
Tools and equipment that can be used during asbestos removal work include asbestos vacuum cleaners, manually operated hand tools and equipment—other than compressed air or high pressure water spray—that have been designed to capture or suppress respirable dust or are used in a way that is designed to capture or suppress respirable dust.
In addition to any equipment required to complete a particular task, the following equipment may be required on-site before the work begins:
    * disposable cleaning rags
    * bucket of water and/or a misting spray bottle
    * sealant
    * suitable asbestos waste container
    * warning signs and/or barrier tape.

Prohibited tools and equipment
Tools and equipment that generate dust must not
