    New NATA Accredited Respirable Dust Testing

    Posted 21st April 2020, Carl Strautins

    Safe Environments are exciting to announce NATA accreditation for respirable dust testing as of 21 April 2020. The measurement of respirable dust is important, particularly in the assessment of crystalline silica. The initial lab assessment by NATA for respirable dust testing included the following national standards and in-house documents that were approved:

    o AS 2985 Workplace atmospheres–Method for sampling and gravimetric determination of respirable dust

    o MDHS 14/4 General methods for sampling and gravimetric analysis of respirable, thoracic and inhalable aerosols;

    o NIOSH Method 0600 Particulates Not Otherwise Regulated, Respirable; and

    o Safe Environments Standard Operating Procedure (SOP) Airborne Contaminant Monitoring: Sampling and Gravimetric Analysis of Aerosols

    The analysis of filters by our lab is open to the public, occupational hygiene consultants as well as complimenting Safe Environments
    occupational hygiene inspection activities accredited to ISO 17020 Conformity assessment – Requirements for the operation of various types of bodies performing inspection. As at February 2020, Safe Environments is the only NATA accredited type A inspection body to perform respirable dust assessments. This is pertinent to establish the reliability of lab results to ensure worker health and assessing compliance with Workplace Exposure Standards (WES).

    While there is no Workplace Exposure Standard (WES) for respirable dust under the model WHS regulations, the NSW Work Health and Safety (Mines and Petroleum Sites) Regulation 2014 requires the mine operator of a mine to minimise the exposure of persons at the mine to dust. There is also a requirement to ensure that no person at the mine is exposed to 8-hour time-weighted average atmosphere of respirable airborne dust– 3 milligrams per cubic metre of air, or in the case of a coal mine, 2.5 milligrams per cubic meter of air.

    Safe Environments lab services can provide inspection or chemical analysis by way of gravimetric analysis to provide reliable results where decisions can be made to protect worker health. For more information, please call 02 9621 3706 or email info@safeenvironments.com.au
