Which option is NOT one of OSHA's five hazard categories?

• A. Ergonomic
• B. Mechanical
• C. Chemical
• D. Biological

Answer: (B)

The idea being tested is how OSHA groups hazards for safety planning. In common OSHA training frameworks, hazards are organized into five broad categories to guide risk assessment and controls. Mechanical hazards aren’t listed as their own category; they’re covered under the broader Physical hazards category, which includes dangers from moving machinery, energy release, and guarding failures. That’s why Mechanical isn’t considered a separate OSHA hazard category. Ergonomic hazards fit as a distinct category because they come from work design and tasks that cause strain or injury over time. Chemical hazards are about exposure to hazardous substances. Biological hazards involve living organisms or their byproducts. These are all treated as separate categories, whereas mechanical issues are handled within Physical hazards.
