Industrial Hygiene
Protecting People. Ensuring Compliance. Driving Operational Excellence.
At OneSource EHS, our Industrial Hygiene (IH) services are led by experienced professionals, including Certified Industrial Hygienists (CIHs) and licensed field technicians, who specialize in identifying, evaluating, and controlling occupational health hazards. Whether you're operating a petrochemical facility, manufacturing plant, or utility infrastructure, we help safeguard your workforce while ensuring compliance with OSHA, ACGIH, NIOSH, EPA, and state regulations.
From strategic risk assessments to chemical-specific air sampling and industrial noise evaluations, we tailor each project to your worksite’s unique exposures—empowering your team to reduce illness, improve safety culture, and protect long-term operations.
Whether you're addressing regulatory limits or proactively managing risk, OneSource EHS provides comprehensive exposure monitoring—using validated OSHA/NIOSH sampling methods, pre-calibrated equipment, and accredited laboratory analysis.
