Friable Asbestos Removal
Friable asbestos removal is a highly dangerous work activity that is specifically controlled under the WHS Regulation 2011 and the How to Safely Remove Asbestos Code of Practice. Entry to the industry is governed by Workcover through the issuing of licences. Murphy’s has the knowledge, skills and experience needed to remove friable asbestos and has the necessary friable class A asbestos removal licence.
Friable asbestos is asbestos containing material that is in powder form or that can be crumbled, pulverised or reduced to a powder by hand pressure when dry.
This material is very easy to disturb and make airborne so it is necessary to have strict high-level control measures in place for the removal of this material. The removal area is enclosed in a temporary bubble structure using plastic sheeting and kept pressurised using negative air pressure units. This prevents asbestos material being removed from contaminating the surrounding environment. Personnel removing friable asbestos are required to wear full disposable coveralls, face covering respirators and gloves. Air monitoring is in place before, throughout and after the asbestos removal is in progress. The removal areas are inspected by an independent licenced asbestos assessor to confirm that the area is clear of asbestos before clearance is granted and the enclosure is taken down.
Some frequent examples of where we have used friable asbestos removal methods include:
– Removal of pipe lagging
– Asbestos cement products in extremely poor condition
– Ceiling insulation containing asbestos
– Asbestos containing dust and debris in large amounts
Bonded Asbestos Removal
Bonded or non-friable asbestos is asbestos containing material where the asbestos is held in a cement matrix, so there is much less likelihood of dangerous asbestos dust and fibres being released if the material is in good condition. Murphy’s have the relevant asbestos removal licences and trained personnel to enable the compliant removal of this hazardous material.
The asbestos material is wet down with PVA glue to prevent the fibres becoming airborne. The material is then wrapped in plastic and transported for disposal at a licenced tip. Personnel are required to wear disposable coveralls, half-face masks and gloves and air monitoring is conducted throughout the removal process.
The process is completed when an independent asbestos assessor confirms the removal area is clear of asbestos materials by issuing a clearance certificate.
Some frequent examples of where we have used non-friable asbestos removal methods include:
– Asbestos cement roof sheeting, e.g. super six
– Asbestos cement external wall cladding sheeting
– Interior asbestos cement fibre sheets
– Bitumen roof and floor coverings
Lead Paint Remediation
Lead paint is often used on buildings and structures painted before 1970. We are able to safely remove and dispose of lead containing paint and have much work experience in this. Safe removal methods involve using coveralls, dust masks and gloves for our personnel and suitable disposal of waste at an appropriate facility.
Hazardous Soil Remediation
Murphy’s is capable of removing asbestos contaminated soil as part of our projects. This may be part of the planned scope of works or due to discovery of the contamination during the course of other works. Murphy’s are licenced asbestos removalists and will apply the required level of safety controls for the removal of the material to take place.
We are able to remove and dispose of Polychlorinated Biphenyls (PCB) on our projects. These often are found in light capacitors and electrical equipment. Removal involves personnel wearing chemically impervious PPE and disposing in leak proof containers at an approved facility.
As part of our services, we are able to conduct hazardous materials testing and compile hazardous material reports. These reports are necessary so the location and nature of hazardous materials is known before the beginning of the project works. They are also a requirement under the WHS Regulations and the Australian Standard for Demolition.
Often, before the work commences, it is necessary to carry out destructive and intrusive testing of the materials which wasn’t possible if a building was occupied or in use. We use fully qualified and competent consultants to undertake and compile our hazardous materials surveys. NATA certified laboratories test samples for the presence of hazardous materials.
