EDP, commissioned by BGIS, conducted background air monitoring for ozone (O³) concentrations and airborne lead (Pb) and hexavalent chromium (Cr[VI]) dust (hazardous dust) in various buildings on the RAAF Base Richmond site in New South Wales.
Monitoring was undertaken to assist BGIS in determining changes in concentrations of the airborne pollutants during the operation of the new Active Oxy bird-deterrent system (OBDS).
The purpose of this assessment was to assist BGIS in determining the impacts of the OBDS on indoor air quality and potential health risks to building occupants following implementation, thereby ensuring compliance with legislative and Defence health and safety standards. Accordingly, EDP completed multiple services, including
- conducting O³ monitoring by collecting real-time data at one-minute intervals over 24 hours at two separate locations within the two nominated buildings
- conducting background Pb and Cr(VI) inhalable dust air monitoring with laboratory analysis of filter samples at a National Association of Testing Authorities (NATA)-accredited laboratory
- comparing O³ monitoring results against the adopted maximum concentration standard for ozone (0.1 ppm) in accordance with Safe Work Australia Workplace Exposure Standards for Airborne Contaminants 2019
- comparing hazardous dust air results against the adopted exposure standard (<0.03 mg/m³) as detailed by Safe Work Australia Workplace Exposure Standards for Airborne Contaminants 2019
- preparing a report detailing the findings of the assessment, including recorded pollutant air concentrations with associated health and safety risks requiring action
