Asbestos Indoor Air Quality Assessment

Steer Environmental completed an indoor air quality assessment prior to potential transaction of a private residence containing an asbestos-concrete coated boiler unit in the Uphill area of Nelson, BC. The assessment was completed in accordance with applicable WorkSafeBC Guidelines and the Occupational Health and Safety Regulation (OHSR). The objective of the assessment was to investigate the potential presence of airborne asbestos fibre concentrations in excess of risk-based standards protective of human health proposed by the US Environmental Protection Agency (USEPA) and deemed acceptable by Health Canada. Asbestos samples in indoor air were collected in accordance with methods and procedures proposed WorkSafeBC, and submitted for laboratory analysis. Analytical results confirmed the presence of asbestos fibres exceeding the proposed USEPA risk-based standard deemed by Health Canada to result in unacceptable cancer risk. Steer Environmental provided guidance and recommendations to the client that a professional abatement contractor be retained to ensure safe handling, decommissioning, and/or disposal of the boiler unit, and that closure sampling be completed following removal of the unit from the residence.
