Which agency's regulation requires qualitative or quantitative fit-testing of respirators?

• A. EPA
• B. OSHA
• C. CDC
• D. DOT

Answer: (B)

The key idea here is understanding who enforces mandatory respirator fit testing in the workplace. The agency with regulations that require both qualitative and quantitative fit-testing as part of a respiratory protection program is the one responsible for workplace safety standards. This agency’s Respiratory Protection Standard mandates that workers wearing tight-fitting respirators must undergo a fit test before first use, and at specified intervals thereafter, using either a qualitative or quantitative method. This ensures the respirator seals properly and protects the wearer from inhalation hazards. Qualitative fit-testing uses a pass/fail taste, odor, or irritation test, while quantitative fit-testing measures the actual seal with instruments to determine a fit factor. Both methods are permitted under the standard, depending on the respirator and situation, but the key point is that the regulation requiring this testing comes from the agency focused on occupational safety and health in workplaces. Other agencies handle different areas: EPA regulates environmental protection and not the enforcement of respirator fit-testing; CDC provides public health guidance and research, with NIOSH offering recommendations and certification but not the same regulatory enforcement of fit-testing; DOT regulates the transportation of hazardous materials, not routine workplace respirator programs.
