The Stakes of Getting This Wrong
Occupational hygiene assessment is a technical specialist discipline. Monitoring conducted with improperly calibrated equipment, using the wrong sampling method for a substance, with inadequate sample duration, or with incorrect data interpretation can produce results that are meaningless — or worse, falsely reassuring. If a monitoring result says exposures are below the WES but the methodology was flawed, workers are being harmed while management believes they are compliant. The business is exposed to regulatory action and civil liability without the protection of a genuine, valid compliance record.
What Credentials to Look For
As outlined in our guide to hiring an occupational hygienist, the minimum credential standard for compliance monitoring is AIOH membership at Hygiene Practitioner level or above, with COH oversight for complex assessments. Beyond AIOH membership, look for: NATA-accredited laboratory partnerships; calibration certificates for equipment; professional indemnity insurance coverage of at least $5 million; and verifiable experience in your specific industry and hazard type.
The Anitech Group Commitment
Anitech Group’s occupational hygiene services are delivered by AIOH-affiliated practitioners working under COH oversight. All sample analysis is conducted by NATA-accredited laboratories. All instruments are maintained and calibrated against traceable standards. Our reports are written to withstand regulatory and legal scrutiny — because the purpose of an assessment is not to produce a document, but to protect workers and demonstrate genuine compliance.
