Occupational Health & Safety

Occupational Health and SafetyAs an occupational health & safety professional or an industrial hygienist, you are continuously auditing, documenting, and taking corrective or preventive actions. It’s the only way to keep your teams safe and healthy—and to stay in compliance.

A strong safety program depends on good data. Only with correct measurements, can you identify risks, report on them with confidence, and make informed decisions.

Measure what's important

TSI develops and manufactures accurate and reliable occupational health and safety instruments to measure what’s important in your safety program.

  • Monitor risks such as heat stress, confined space gases, noise, and particulate mass.
  • Evaluate workplace exposure, including short-term and long-term exposure to dust, particles, or gases.
  • Build strong respiratory protection programs with quantitative fit testing.
  • Optimize comfort and productivity with HVAC and industrial ventilation tools and indoor air quality assessments.
