OSHA 501 Industry Trainer Practice Test

Industrial hygiene is the science of anticipating, recognizing, evaluating, and controlling workplace hazards to protect workers’ health. It involves identifying what in the work environment could harm people—such as chemical, physical, and biological hazards—and then measuring exposures, understanding how those hazards reach workers, and applying controls to reduce or eliminate risk. This approach follows a practical path: foresee potential hazards, assess the level of exposure, implement effective controls (preferring elimination, substitution, engineering and administrative controls before relying on personal protective equipment), and continually monitor and improve the program to keep health risks low.

The other options miss the core purpose: predicting every safety incident isn’t feasible or the focus; designing ergonomic furniture is a specific design task rather than the health-focused practice of hazard prevention; and managing benefits and compensation falls under human resources, not workplace safety health science.
