An Occupational Hygiene Survey in South Africa: What Happens During One and Why You Need It
An occupational hygiene survey in South Africa is a systematic examination of workplace health hazards, exposure levels and existing controls. For OHS and appointed managers and employers advised to commission one, learning the process makes it easier to prepare staff, provide site access and evaluate the final findings.
IOH Solutions is a leading SANAS-accredited, SAIOH-registered and DoL-registered Approved Inspection Authority under the Occupational Health and Safety Act 85 of 1993.
An Occupational Hygiene Survey in South Africa: What Does It Actually Do?
An occupational hygiene survey in South Africa identifies, evaluates and measures hazards such as noise, airborne contaminants, heat, vibration, illumination and biological agents. The occupational hygienist begins with a site walk-through, discussions with management and workers, and a review of relevant records.
An occupational hygiene assessment is more than one measurement exercise. A health risk assessment considers hazards and risk, while the survey supplies objective exposure data that can be compared with applicable Occupational Exposure Limits (OELs). The two activities work together, but they are not identical.
The Survey Process: Step-by-Step
The hygienist first learns how the workplace operates, which tasks create potential exposure, and which employees may be affected. Workers performing similar tasks under comparable exposure conditions are grouped into similar exposure groups.
Next comes a monitoring strategy. The hygienist selects representative employees, locations, tasks and sampling periods. Occupational hygiene monitoring in SA may include personal or area air sampling, noise monitoring, illumination readings, thermal measurements or other specialised tests, depending on the hazards identified.
Some samples require laboratory analysis using specialised sampling equipment. The findings are assessed against applicable OELs and other recognised criteria.
Preparing Your Workplace for the Hygienist
A workplace hygiene survey works best if the consultant can access relevant production areas, machinery, storage spaces, ventilation systems and employee workstations. Arrange access permissions in advance and advise supervisors that normal work should continue during representative sampling.
Useful information includes process descriptions, chemical inventories, previous survey reports, employee numbers, work schedules, PPE details, incident records and existing control measures. A site contact should also be available to explain unusual tasks or production cycles.
What Will You Receive in the Final Report?
For an occupational hygiene survey in South Africa, the report should explain what was assessed, where measurements were taken, who was sampled, the methods used and the results obtained. It should identify exposures above applicable OELs, prioritise findings and provide control recommendations.
What Happens After the Survey?
Employers must act on significant risk findings. Under the Hazardous Chemical Agents Regulations, employers must assess exposure and ensure future exposure is prevented or adequately controlled. Records and control measures also require appropriate management.
How Often Should Surveys Be Repeated?
No single interval applies to every occupational hygiene survey. Specific regulations can prescribe assessment periods for particular hazards. However, changes to processes, equipment, materials or exposure conditions can justify earlier reviews.
