Further specific guidance on managing asbestos when demolition and refurbishment work is being carried out can be found in the:

Lead
Lead is found in paint, old water pipes and other plumbing fittings, sheet lead, solders, lead flashing, lead light windows and glass. The age of a structure may be directly related to the amount of lead that can be present (see Table 2).
Table 2 Lead sources

Approximate date of construction  Sources of lead hazards

1920 - 1978                       Paint
1920 - 1978                       Plumbing
1923 - 1986                       Automobile exhaust
                                  (may accumulate as ceiling dust)

If it is suspected that the structure contains lead based paint, a test for the presence of lead should be conducted.
The precautions which should be taken when demolishing materials containing lead include:
    * minimising the generation of lead dust and fumes
    * cleaning work areas properly during and after work
    * wearing the appropriate PPE, and
    * maintaining good personal hygiene.
Further information can be found in AS 4361.1 Guide to lead paint management-Industrial applications. Testing can recognise dried paint film with more than 1 per cent (by weight) to be lead-containing paint.

Polychlorinated biphenyls

Workers can be exposed to Polychlorinated Biphenyls (PCBs) when dismantling electrical capacitors and transformers or when cleaning up spills and leaks. Appropriate control measures should be implemented when handling damaged capacitors to ensure that any spillage does not contact workers and is appropriately cleaned up and disposed of.

Any equipment or parts containing PCBs should be placed in a polyethylene bag and then placed into a marked sealable metal container.
If PCBs cannot be transported immediately for disposal, all containers should be stored in
a protected area which prevents any discharge of PCBs to the environment.
PPE including gloves made of materials that are resistant to PCBs (for example polyethylene, nitrile rubber or neoprene), should be provided to workers and worn when there is any likelihood of exposure to PCBs.

Synthetic Mineral Fibres
Synthetic mineral fibres are used extensively for insulation in building walls and ceilings as well as on items such as air-conditioning duct work. The specific material should be identified and control measures implemented relevant to the manufacturer's instructions.

PPE should be provided to workers and worn when insulation is being removed during the demolition process and dust should be suppressed by damping down.

4.3 Securing the work area

Exclusion zones
To protect workers undertaking demolition activities, exclusion zones should be considered to prevent unauthorised personnel entering work areas.
A system to prevent falling objects impacting on workers should be implemented to protect
