Bitrex Fit Test Solution | Draeger

Fit Test Solution (Bitrex) for use in qualitative fit testing of respirators. Reveals leakage by taste response; ensures mask seal integrity.

The solution is used in conjunction with Draeger's Quantitative Fit Test Kits to evaluate the fit of respirators. It uses Bitrex (denatonium benzoate), a bitter-tasting substance, which the wearer should not be able to taste if the mask fits properly.

Key Features:

1. Bitrex (Denatonium Benzoate):

   • Bitter Taste: Bitrex is one of the most bitter substances known to humans. It is used to detect leaks in the respirator's seal. If the wearer tastes the solution, the mask does not fit correctly, indicating a need for adjustments.

   • Safe and non-toxic: The Bitrex solution is safe for use and has no harmful effects on the user, though it is unpleasant if tasted.

2. Quantitative Fit Testing:

   • The solution is part of a quantitative fit testing system where a machine measures the concentration of the Bitrex solution in the air surrounding the wearer. If a leak is detected, the wearer will taste the Bitrex, signaling a poor fit.

   • This type of test provides a numerical value for the fit factor, which is more precise compared to qualitative tests.

3. Compatibility:

   • The Bitrex solution is typically used with Draeger’s Fit Test Machines (e.g., the Draeger Fit Test 3000), allowing for a standardized and reliable test.

4. Easy to Use:

   • The testing process involves the wearer donning a respirator and being exposed to a controlled concentration of the Bitrex solution. The wearer’s response (taste) is monitored, and the test gives real-time feedback.

5. Testing Environment:

   • The Bitrex solution should be used in a controlled environment where respiratory protection fit is critical, such as in hazardous environments with potential chemical, biological, or particulate hazards.

Applications:

• Occupational Safety: Commonly used in industries where workers are exposed to hazardous materials (e.g., chemicals, biohazards, particulates) and need to ensure their respiratory protection is effective.

• Healthcare: Essential for ensuring that healthcare workers are properly fitted with respirators, particularly in settings where airborne infectious diseases (like tuberculosis or COVID-19) are a concern.

• Military and Emergency Response: Used to confirm that respiratory protection is suitable in hazardous environments such as chemical warfare or biohazard incidents.

Usage Instructions:

• Typically, the Bitrex solution is sprayed into a test chamber while the wearer dons a respirator.

• The wearer is asked to perform various exercises (e.g., deep breathing, head movements, talking) to simulate real-world use.

• If the wearer tastes the Bitrex solution, the fit is inadequate, and adjustments to the respirator should be made until an acceptable fit is achieved.

Packaging:

• Available in bottles or vials containing the Bitrex solution. The solution is often supplied in small quantities since only a small amount is needed for the test.
