disturbed during work activities, it must be removed. This includes removing visible fragments of bonded ACM from exposed trench faces and those areas of the site where intrusive works may be carried out (e.g. to install utilities). The removal of visible asbestos should be appropriately managed and full details recorded (this information is required for assessing asbestos concentration in soil – refer Section 4.10). Visible asbestos should be removed prior to excavation/construction works commencing. Consult the relevant Code of Practice for more detailed information.

4.4              Terminology for asbestos contamination in soil
For the purpose of assessing the significance of asbestos in soil contamination, three terms are used in this Schedule which are based on guidance developed by the Western Australian Department of Health (WA DoH, 2009). The equivalent terms used in work health and safety legislation are listed in Table 6:

Bonded asbestos containing material (bonded ACM)
Bonded ACM comprises asbestos-containing-material which is in sound condition, although possibly broken or fragmented, and where the asbestos is bound in a matrix such as cement or resin (e.g. asbestos fencing and vinyl tiles). This term is restricted to material that cannot pass a 7 mm x 7 mm sieve. This sieve size is selected because it approximates the thickness of common asbestos cement sheeting and for fragments to be smaller than this would imply a high degree of damage and hence potential for fibre release.
Bonded ACM is equivalent to 'non-friable' asbestos in Safe Work Australia (2011), which is defined therein as 'material containing asbestos that is not friable asbestos, including material containing asbestos fibres reinforced with a bonding compound'.

Fibrous asbestos (FA)
FA comprises friable asbestos material and includes severely weathered cement sheet, insulation products and woven asbestos material. This type of friable asbestos is defined here as asbestos material that is in a degraded condition such that it can be broken or crumbled by hand pressure. This material is typically unbonded or was previously bonded and is now significantly degraded (crumbling).

Asbestos fines (AF)
AF includes free fibres, small fibre bundles and also small fragments of bonded ACM that pass through a 7 mm x 7 mm sieve. (Note that for bonded ACM fragments to pass through a 7 mm x 7 mm sieve implies a substantial degree of damage which increases the potential for fibre release.)
