Type 1 - Location and assessment inspections (presumptive asbestos inspections): Presumptive asbestos inspections are undertaken by a visual walk through within accessible areas of the building or house to locate and assess materials suspected of containing asbestos. These materials are presumed to contain asbestos and a risk assessment or algorithm is calculated. Presumptive asbestos inspections defer testing for asbestos until a later time. This is usually before demolition, refurbishment or to assess the potential health risk due to deterioration of the presumed asbestos material.
Type 2 - Location and assessment inspections (sampling asbestos inspections): Sampling asbestos inspections are similar to Type 1 presumptive asbestos inspections; however representative samples of the suspected asbestos containing material are collected to confirm the presence and type of asbestos detected.
Type 3 – Full access sampling and identification inspections (pre demolition/major refurbishment asbestos inspections): Demolition asbestos inspections provide the location of the asbestos within the building that is required to be removed before demolition. This may include partial demolition to gain access into wall cavities and the like. This is intended to partially comply with the hazardous materials auditing procedure (clause 1.6) of AS 2601 Demolition of Structures.
The results of asbestos inspections are tabulated with an asbestos register and are an essential part of an asbestos management plan. Asbestos inspections should be conducted on a yearly basis, or sooner if the asbestos containing material has been disturbed or removed, to re assess the potential risk to health.
