Which statement best describes qualitative fit testing for respirators?

• A. It relies on the wearer detecting taste, smell, or irritation.
• B. It uses instruments to measure seal leakage (CPC).
• C. It yields numerical leakage values via a manometer.
• D. It requires no subjective input from the wearer.

Answer: (A)

Qualitative fit testing relies on the wearer’s senses to judge respirator fit. A test agent that can be tasted, smelled, or causes irritation is introduced around the face while the wearer performs movements to simulate workplace conditions. If the agent is detected inside the respirator, it indicates a leak and the fit fails. Because the decision is based on the wearer’s perception rather than an instrument reading, the result is a simple pass/fail rather than a numerical leakage value. This contrasts with quantitative fit testing, which uses instruments to measure leakage and provides numerical results. Since it depends on individual sensory detection, its effectiveness can vary between workers and it isn’t suitable for everyone or for all types of respirators.
