Our occupational hygiene specialists assist companies in identifying contaminants present on a site.

During industrial hygiene interventions, we can assess workers’ exposure to contaminants, verify compliance with occupational exposure standards and issue clear recommendations for maintaining and improving worker health and safety.

Our studies follow recognized sampling protocols and current standards. Our experienced staff investigate and sample contaminants using high-precision devices, then perform analyses in recognized and accredited laboratories, which ensures that results are reliable.
