Which of the following are cited as federal government agencies?

• A. NIOSH
• B. OSHA
• C. NIST
• D. All of the above

Answer: (D)

This question checks recognition of federal agencies that appear in safety and regulatory references. NIOSH, OSHA, and NIST are all U.S. federal entities with distinct roles that influence workplace safety and standardization. NIOSH (National Institute for Occupational Safety and Health) conducts research and provides guidance on occupational health and safety. OSHA (Occupational Safety and Health Administration) creates and enforces workplace safety regulations. NIST (National Institute of Standards and Technology) develops measurement science, standards, and test methods used across industries, including safety-related technologies. Because each operates at the federal level and contributes to safety, health, or standards information you might encounter in OFM materials, all three are cited as federal government agencies. That makes “All of the above” the correct choice.
