Occupational hygiene surveys and monitoring.
Fifteen survey disciplines, each with its own statutory trigger, its own governing standard and its own calibrated instrument. Sampling is analysed by a SANAS ISO/IEC 17025 accredited laboratory and reports are signed by a Registered Occupational Hygienist.
Measured, not assumed
Occupational hygiene happens where the work does, on the plant floor, with calibrated instruments.
The fifteen disciplines
Each survey answers a different statutory question. Together they establish what your people are actually exposed to.

Occupational hygiene is not a once-off exercise. The regulations set the clock.
Why the survey decides the medical
The measured exposure is what writes the medical surveillance programme. A noise rating determines who needs audiometry and how often; a solvent exposure determines who needs biological monitoring. Get the survey wrong and the medicals are wrong with it.
Because we run both, the exposure data and the health data sit on one record, so a shifting noise rating changes the audiometry schedule automatically, rather than being discovered at the next audit.
Our accredited inspection body
OccuFit Occupational Hygiene Inspection Body holds its own SANAS accreditation as a Type A Inspection Body (OH0237, SANS 17020) and publishes its approved scope separately, as required.
