Which branch of OSHA conducts research and experimental programs to develop criteria for safety and health standards?

• A. NIOSH
• B. OSHA Directorate of Research
• C. CDC
• D. NIST

Answer: (A)

This question is asking which organization is responsible for the scientific research and development of criteria that shape safety and health standards. The best answer is NIOSH—the National Institute for Occupational Safety and Health. NIOSH conducts research, experiments, and field studies to identify workplace hazards, assess risks, and generate data, exposure limits, and practical guidelines. These findings provide the technical basis that OSHA uses when crafting and updating safety and health standards and recommendations. In other words, NIOSH supplies the scientific evidence and criteria that inform policy and rulemaking, while OSHA handles enforcement and program implementation.

The other options don’t fit this role. OSHA’s own structure focuses on enforcing standards and guidelines rather than conducting the primary research that creates those standards. The CDC is the parent agency of NIOSH, not the specific research arm itself, and NIST is centered on measurement standards and technology not specifically occupational safety criteria.
