Question

1. what does it mean if during the fit test you taste a sweet or bitter taste?

• the respirator fits properly
• the respirator does not fit properly
• the respirator is fit too tightly
• the respirator is not the proper n95 type

Explanation:

🆕 New Concept Discovered: Qualitative Fit Testing (QLFT)
Detecting leaks using taste or smell

Step 1: Understand the purpose of a respirator fit test

A respirator fit test ensures that a tight-fitting respirator facepiece seals properly to the wearer's face so that contaminated air cannot leak into the mask.

Step 2: Analyze qualitative fit testing (QLFT)

During a qualitative fit test (QLFT), a harmless aerosol with a distinct taste (such as a sweet substance like saccharin, or a bitter substance like Bitrex) is sprayed around the outside of the respirator while the wearer performs various movements.

• If the respirator has a proper, airtight seal, the wearer should not be able to taste or smell the test agent.
• If the wearer detects a sweet or bitter taste, it means the aerosol has leaked through the seal into the mask.

Step 3: Determine the correct option

Because tasting the substance indicates that the aerosol has bypassed the seal, detecting a sweet or bitter taste means that the respirator does not fit properly.

Answer:

The respirator does not fit properly
