Which term best describes the organization abbreviated NIOSH?

• A. National Institute of Occupational Safety & Health
• B. National Institute of Occupational Science & Hygiene
• C. National Institute of Occupational Safety and Hygiene
• D. National Institute of On-Site Safety & Health

Answer: (A)

NIOSH describes a U.S. federal agency focused on protecting workers by researching hazards, evaluating risks, and issuing guidance to prevent work-related injuries and illnesses. The best term is the National Institute for Occupational Safety and Health, which captures the official focus on safety and health in the workplace. This reflects its role under the CDC in guiding occupational safety standards and practices.

Other wording shifts the name or scope: changing “for” to “of” or using “Science & Hygiene” or “On-Site” suggests a different organization or a narrower focus, and doesn’t accurately describe the agency or its mission.
