Occupational health and safety technicians test workplaces for potential hazards. They help create plans to improve workplace safety.

Occupational health and safety technicians evaluate the safety measures of different work spaces. They provide consultation to businesses to help prevent hazards. Technicians run tests to see if there are any environmental hazards such as exposure to radiation, chemical or biological hazards, or excessive noise. They make sure safety gear is working properly and replace it if necessary. Sometimes they prepare orders for new equipment. 

Occupational health and safety technicians make sure health and safety standards are being met. If they find safety issues, they create plans to improve safety. They train workers in safety related procedures and create emergency response drills. They keep logs of all work activities. 

In addition, they also inspect fire suppression systems or portable fire systems to ensure proper working order. In the event of a fire, they help direct rescue and firefighting operations. 

Occupational health and safety technicians also review records and reports concerning laboratory results, staffing, floor plans, fire inspections, or sanitation to gather information for the development or enforcement of safety activities. They occasionally prepare documents for legal proceedings.
