According to NSW Occupational Health and Safety Regulation 2001, an employer must ensure that asbestos work is carried out in accordance with NOHSC: 2002 (2005). Control and performance of certain aspects of the work must be undertaken by a Competent Person who is independent of the removal contractor. The Competent Person should report direct to and be employed by the Client (that is to the employer or site controller).
According to Getex , a clearance inspection is an examination of the area, which has undergone an asbestos removal. It is undertaken prior to completion of asbestos work in that area. It is the principal component in determining the successful removal of asbestos containing materials (ACM).
A clearance inspection is done prior to the resumption of normal work in the area by unprotected personnel and must be conducted by a “Competent Person”, independent from the person responsible for the removal work. Only a “Competent Person” can issue a clearance certificate.
Before a clearance is granted for an asbestos work area to be re-occupied, there must be a thorough clearance inspection.
The clients (that is the employer or site controller) should supply details of their asbestos removal requirements to the asbestos removalist and work specifications should address issues, which include the arrangements for clearance inspections and air monitoring. A competent person can act on behalf of the client to provide the required details to the removalist.
A competent person must inspect the surface from which the ACM was removed at a close range. A competent person must go everywhere the asbestos removalist went, physically disturbing the surfaces and/or components, to reveal any visible debris.
With the possible exception of materials such as cement and paint, the competent person should not attempt to distinguish between materials thought to be asbestos material or non asbestos.
All air monitoring requirements, such as location, rate, and frequency of sampling, should be determined by an independent competent person and performed in accordance with the NOHSC Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres [NOHSC: 3003 (2005)].
The National Occupational Health & Safety Commission (NOHSC) is now referred to as the Australian Safety & Compensation Council, 20 October 2005.
Prior to commencement of works, a part of the planning process should include the need for “clearance monitoring.” Control monitoring results and experience will assist the competent person in determining the level and/or need of clearance monitoring.
NATA is Australia’s government-endorsed provider of accreditation for laboratories and similar testing facilities (www.nata.asn.au). To support their accreditation programmes, NATA also operates proficiency testing programmes for asbestos fibre counting (the National Asbestos Program-NAP through Proficiency Testing Australia), and of which GETEX is a participant. The NATA accreditation and proficiency testing enable users to select reliable testing and measurement services.
Getex can help people to act as a Competent Person in accordance with NOHSC: 3003 (2005) and NOHSC: 2002 (2005) and OH&S Regulation 2001. Getex are NATA accredited for Airborne Asbestos Fibre Counting and Volume Measurement (which enable to issue reports in fibres/mL). Getex accreditation number is 15404.
Getex are involved in monitoring and management of asbestos. Getex recommend and implement cost-effective monitoring programmes and clearance inspections in any part of Australia and overseas.
