What does a quantitative fit test assess?

• A. The amount of leakage into the respirator
• B. The color of the respirator
• C. The cost of the respirator
• D. The durability of the respirator

Answer: (A)

The test focuses on seal integrity by measuring how much leakage from the outside air gets into the respirator while you wear it and perform standard movements. It uses instrumentation to compare the outside particle concentration with the inside concentration, giving a numerical fit factor. A higher fit factor means less leakage and a better seal, indicating the respirator provides the expected protection for that person. It doesn’t assess color, cost, or durability—those factors aren’t related to how well the facepiece seals to the face.
