Which statement best differentiates qualitative from quantitative respirator fit testing?

• A. Qualitative testing uses only instruments to measure leakage.
• B. Quantitative testing relies on taste, odor, or irritation cues.
• C. Qualitative testing yields numerical leakage values.
• D. Qualitative testing uses taste/odor or irritation; quantitative uses instruments to measure leakage.

Answer: (D)

Differentiating qualitative from quantitative respirator fit testing comes down to how leakage is detected. Qualitative testing relies on the wearer’s senses—taste, odor, or irritation—to judge whether the fit is adequate. It’s a subjective, pass/fail method with no numerical leakage value. Quantitative testing uses instruments to measure leakage and provides a numerical fit factor or leakage value, giving objective data about the seal. The statement that best captures this difference is that qualitative testing uses taste/odor or irritation cues, while quantitative testing uses instruments to measure leakage. The other descriptions mix up which method uses sensory cues and which provides numerical data.
