Moldex Bitrex Instructions

BITREX
A. EQUIPMENT REQUIRED
1. Moldex Bitrex Qualitative Fit Test Kit (#0102)
2. Moldex Bitrex Quantative Test Hood (#0201)
3. Nebulizer #1 (BITREX Sensitivity Solution) (#0301)
4. Nebulizer #2 (BITREX Fit Test Solution) (#0302)
5. Two sets Replacement Nebulizer Inserts
6. BITREX Fit Test Solution Applicator Tube (#0504)
7. BITREX Sensitivity Solution Applicator Tube (#0503)
8. Appropriate Moldex Respirators*
*Use with any Moldex N, R or P class disposable respirator. This fit test kit may also
be used with any Moldex half mask or full face respirator by using any N, R or P class filter.
**This fit test kit may also be used with any Moldex half mask or full face respirator by using any
N, R or P class filter as a stand alone or in combination with any chemical cartridge. The maximum
fit-factor allowed for qualatatively fit testing a Full Face is 10.
B. NEBULIZER PRE-INSPECTION AND
PREPARATION
1. Remove the top half of the nebulizer
by unthreading it from the bottom
half. (Repeat for each nebulizer)
2. Using your index finger lightly push
down on the Atomizer to ensure that it
is pushed down all the way onto the
bottom half of the nebulizer. (See
Diagram 1). (Repeat for each nebulizer)
3. Inspect and ensure that the black
O-ring is properly seated.
(Repeat for each nebulizer)
4. Replace the top half of nebulizer and remove plug from nebulizer exhaust
port. (Repeat for each nebulizer)
C. BITREX APPLICATOR INSTRUCTIONS
5. WARNING: When crushing the applicator tubes to release the product,
it is important to wear protective gloves. It is also important to "pinch"
the applicator tube to break the glass ampoule when releasing the liquid
into the tube. DO NOT BEND THE TUBE! (See Diagrams 2 and 3)
6. PREPARATION: Remove Sensitivity Test Applicator and/or the Fit Test
Applicator from its storage box. With the fill tip pointed upward, pinch
along the full length of the applicator tube using your thumb and forefinger
until glass ampoule inside of the applicator tube is thoroughly crushed.
(Warning: It is important to keep the applicator tip pointed upward when
pinching the tube. This is to prevent the solution from squirting out during
the pinching process.) (See Diagram 4)
7. Remove the End Cap from the nebulizer. Insert the applicator tip into the
opening of the nebulizer. Squeeze along the applicator tube to transfer the
solution from the applicator down into the nebulizer until the applicator is
completely drained of the solution. (Warning: Do not attempt to remove
the tip of the applicator. It contains a porous filter which is designed to
allow the solution to pass through it while filtering out the glass ampoule
particles. It is also not necessary to puncture a hole or cut the tip of the
applicator. The applicator tip already has the proper hole size in it to allow
the solution to squirt into the nebulizer.) (See Diagrams 5 and 6)
(Note: It is recommended that the protective end cap be replaced back on
the nebulizer until the test is ready to be performed.) Use the foam
cushion insert in the fit test kit to hold the nebulizer(s) upright.

8. Once the applicator solution has been drained into the nebulizer, it can
safely be disposed.
9. Ensure that each nebulizer is able to produce solution mist via the exhaust
port by removing plug from Breather Vent and squeeze bulb 4-5 times. If
solution mist is not visible or seems very weak, carefully (so not to spill the
solution) remove the top half of the nebulizer by unthreading it from the
bottom half and repeat #B-2. (See Diagram 1). (Repeat for each nebulizer)
D. TASTE SENSITIVITY SCREENING
Purpose: This test is done to ensure that the person being fit tested can
detect the taste of BITREX at sufficiently low levels to make the fit test valid.
1. Ensure that the test subject does not eat, drink, smoke or chew gum for
15 minutes before the test.
2. Explain the screening and fit testing procedures to the subject.
3. Instruct subject to put on the hood without a respirator.
4. Position the hood forward so there is about six inches between the
subject's face and the window. This is especially important for the fit test.
It allows free movement of the head when the subject is wearing a
respirator and helps ensure even dispersion of the aerosol around the
face seal area.
5. Instruct the test subject to breathe with their mouth slightly open and
tongue extended.
6. Using the nebulizer labeled BITREX Sensitivity Solution, inject the aerosol
into the hood through the hole in front of the enclosure. Inject ten (10)
squeezes of the bulb, fully collapsing and fully expanding the bulb on
each squeeze.
7. Ask the subject if he can detect the bitter taste of BITREX.
8. If the subject does not detect bitter taste, inject an additional ten
squeezes into the hood.
9. If the subject still does not detect bitter taste, inject an additional ten
squeezes, for a total of 30 squeezes.
10. If 30 squeezes were inadequate to elicit a response from the subject,
this subject cannot be fit tested with the BITREX test. Another fit test
method must be used.
11. If the subject could detect bitter taste, the number of squeezes required
to produce a taste response should be noted, i.e., 10, 20 or 30
squeezes, even if subject tasted the BITREX on a number of squeezes
other than multiples of ten.
12. Remove the hood. Wait a few minutes, to give the subject time to clear
the taste from his mouth, before proceeding to the fit test. A drink of
water during this time will aid in removing the bitter taste. Use a paper
towel to wipe the subject's mouth of any residue (also wipe mustaches).
