Qualitative Risk Assessment
The identification survey is the first step in the hazardous building materials risk management process. The next phase is to evaluate the risk the hazardous building materials present to the occupants and users of the building / structure. The risk assessment is performed by consideration of many interrelated factors including; the condition of the materials, nature of the products, exposure pathways and any other information considered important or relevant. These factors are also utilised in the process of determining appropriate hazard control strategies and recommendations for the timing of future assessment activities. Hibbs & Associates Pty Ltd has developed a priority rating system to rank the hazardous building materials. This is used to assist with the development of a comprehensive hazardous materials management and abatement programme.
Asbestos Containing Materials
The qualitative health risk assessment for asbestos-containing materials is based upon an evaluation of factors, such as the friability, location and condition of the identified materials, whether the nature of the work carried out in the area is likely to disturb the asbestos and the likelihood (and quantum) of fibres released entering the occupied space.
Synthetic Mineral Fibre Products
The qualitative risk assessment of synthetic mineral fibre materials identified is based upon an evaluation of factors, such as the friability, location and condition of the identified materials, whether the nature of the work carried out in the area is likely to disturb the synthetic mineral fibre and the likelihood (and quantum) of fibres released entering the occupied space.
Polychlorinated Biphenyl Components
The qualitative risk assessment is based upon an evaluation of the condition of the component item for leaking PCB oil and the potential for contact with PCB oil or loss of PCB oil to the environment.
Lead-based Paint Systems
The qualitative risk assessment for lead-based paint systems is based upon an evaluation of factors, such as the condition of the paint membrane (adhesion to the substrate, surface deterioration i.e. chalky or cracked etc.), an examination of the paint layers (i.e. inner layers of lead based paint covered with outer layers of lead-free paint to provide a protective coating) and location of the paint system (i.e. food areas, accessibility to children, etc).
