IHIndustrial Hygiene

The science of anticipating, recognizing, evaluating and controlling workplace hazards that can cause illness or injury.

Reviewed June 2026 by Enterprise Health

Key facts

  • Anticipates, recognizes, evaluates and controls workplace hazards.
  • Uses the hierarchy of controls to reduce exposure.
  • Monitoring plans define surveillance needs and cadence.

What it means

Industrial hygienists assess chemical, physical, biological and ergonomic hazards — sampling air, noise and surfaces — and design controls following the hierarchy of controls. Their monitoring plans define who needs medical surveillance and how often. Enterprise Health's optional IH module documents annual monitoring plans, schedules due dates and tracks monitoring activities so exposure data and medical surveillance stay linked.

Frequently asked

What do industrial hygienists do?

They assess chemical, physical, biological and ergonomic hazards — sampling air, noise and surfaces — and design controls following the hierarchy of controls. Their monitoring plans determine who needs medical surveillance.

How does industrial hygiene connect to the medical record?

IH monitoring plans identify exposed workers and the cadence of testing, which feeds surveillance. Keeping exposure data and the medical record linked is what makes surveillance accurate.
