Frequently asked questions

What does an industrial hygienist do?

An industrial hygienist protects workers from health hazards by measuring and controlling workplace exposures to noise, dust, chemicals, heat and other agents. They survey the workplace, monitor exposures, compare them to limits, and recommend controls. They keep sound monitoring records and help protect workers from long term occupational illness.

What qualifications do you need to be an industrial hygienist?

Most industrial hygienists hold a degree in science or engineering with occupational hygiene training, and a certification in industrial hygiene is an advantage. Employers look for skill in exposure monitoring, knowledge of occupational exposure limits, the ability to assess ventilation and recommend controls, and careful record keeping and instrument calibration.

What is the difference between industrial hygiene and safety?

Safety focuses on preventing immediate injuries from hazards like machines, falls and fire. Industrial hygiene focuses on health hazards that harm workers over time, such as noise, dust and chemical exposure. An industrial hygienist measures these exposures and recommends controls, working alongside safety to protect both short and long term worker health.
