A SPECIALIST YOU CAN TRUST
Qualitas Occupational Consulting provides professional occupational hygiene services that help organisations protect worker health, meet legal requirements, and manage workplace risk with confidence. Every assessment is led by Christo de Wet, an occupational hygienist registered with the Southern African Institute for Occupational Hygiene (SAIOH), with 15 years of experience. We work across South Africa, and have also carried out assessments in Botswana and Kazakhstan.
​
We deliver scientifically sound assessments across noise, chemical agents, heat and cold stress, indoor air quality, ergonomics, vibration, asbestos, non-ionising radiation, biological agents, and facilities-related risks — supported by clear, defensible reporting.
Our focus is simple: accurate measurement, practical solutions, and compliance you can rely on.
OUR APPROACH
We combine technical expertise with a strong understanding of real-world operations.
Our assessments are conducted using calibrated equipment and recognised methodologies, aligned with the Occupational Health and Safety Act (85 of 1993) and applicable South African regulations. We don’t just identify hazards — we help you understand the risk and implement controls that are practical, effective, and sustainable.
​
Our reports are written for management, SHEQ teams, and auditors, making compliance clear and actionable.

How we work

Your report explains what was found, what the law requires and what to do next, in plain language for management, SHEQ teams and auditors. Reports are handled confidentially under our ISO/IEC 17020 quality system.
