What Is a Qualitative Fit Test?

The QLFT evaluates how well a half-face respirator fits by detecting air leaks using your sense of taste or smell.

📌 Designed for respirators requiring a fit factor of 100 or less

How the Test Works

• You wear a respirator and testing hood
• A harmless aerosolized agent is released into the hood
• You perform a series of breathing and movement exercises

👉 If you taste or smell the agent, the respirator seal is not adequate

Pass / Fail Criteria

• PASS → No detection of test substance (proper seal)
• FAIL → Detection of taste/smell (air leakage present)

📌 A failed test means the respirator must be adjusted or replaced and retested

Test Agents Used

• Bitrex → Bitter-tasting agent (most commonly used)
• Saccharin → Sweet-tasting alternative

👉 Used to safely and effectively detect respirator leakage

Why This Test Is Important

QLFT helps ensure:

✔ Proper respirator fit and seal
✔ Protection from airborne hazards
✔ Compliance with OSHA workplace safety standards
