Fit testing is performed to verify that a respirator seals correctly on the wearer’s face.

• A. False
• B. It measures the chemical concentration
• C. True
• D. It tests the PPE color

Answer: (C)

The main idea here is that fit testing checks whether a respirator forms a proper seal against the face. If the seal isn’t right, air can leak around the edges and contaminants can bypass the filter. That’s why fit testing is all about the fit and seal, not about measuring the concentration of chemicals in the air or the color of the PPE. There are two common approaches: qualitative tests, which rely on the wearer’s senses (taste or odor) to detect leakage, and quantitative tests, which use instrumentation to measure how much leakage occurs. In short, ensuring a correct seal is exactly what fit testing is for, so the statement is true.
