Overview

Quantitative airborne exposure monitoring for hazardous chemical agents identified through the HCA Risk Assessment. Personal and/or area air sampling is conducted with samples submitted to a SANAS-accredited laboratory for analysis and comparison against Occupational Exposure Limits.

Laboratory analysis required

Methodology

  • Personal air sampling using calibrated sampling pumps and appropriate collection media
  • Area (static) sampling where personal sampling is not feasible
  • Sampling for specific agents: dust, fumes, vapours, gases, metals
  • Submission of samples to SANAS-accredited laboratory
  • Comparison of results against Occupational Exposure Limits (OELs)

What You Receive

  • HCA exposure monitoring report with laboratory analytical results
  • Comparison against OELs (TWA and STEL where applicable)
  • Compliance status per substance per worker group
  • Recommendations for exposure reduction and medical surveillance
Applicable Legislation:
Hazardous Chemical Substances Regulations, 1995 (Regulation 6 & 12); OHS Act 85 of 1993.

Frequently Asked Questions

What are Occupational Exposure Limits (OELs)?
OELs are the maximum airborne concentrations of substances to which workers may be exposed over an 8-hour working day without adverse health effects. They are published in the HCS Regulations and updated periodically.
