Which option best describes the purpose of a fit test?

• A. To check the fit of the facepiece by measuring leakage
• B. To measure the oxygen concentration in the room
• C. To test battery life of powered respirators
• D. To determine the color of the respirator

Answer: (A)

A fit test is all about whether the respirator can form a proper seal on the wearer's face. It checks for leakage around the facepiece as you perform typical movements and speaking, using a harmless test agent or measurements to reveal any gaps. This confirms that the chosen model and size fits the individual well and provides the intended protection. Measurements of room oxygen, battery life of powered respirators, or the respirator’s color do not assess the seal or protection, so they aren’t describing the purpose of a fit test.
