Inspecting, Donning, and Doffing Half-Face Air-Purifying Respirators
(Mandatory Performance Test)(1)
"(1) Alert: For any trainee who does not have documented medical clearance to wear an air-purifying
respirator, the performance test can be performed with the removal of the cartridges/filter elements
from the respirator facepiece after step 4 on the checklist. Step 9, the negative pressure user seal check,
will be performed by placing the palms of the hands over the inhalation valve inlets and inhaling slightly
for a count of 10.
Copy of the performance checklist for each trainee
Instructions:
Demonstrate, practice, coach, and talk through the task as a training
exercise; repeat as needed.
Divide trainees into pairs to work together.
Require each trainee to take the performance test while the second
trainee observes.
Require each trainee to talk through his/her thinking, inspection,
and decision-making process while they complete the performance test.
Score each trainee on each task, using the performance checklist.
Trainees will be given two separate scores. One will be for correct
performance of the operations listed (e.g., the trainee actually removes
the exhalation valve cover and checks for foreign material) and the
second score will be for making the correct decisions (e.g., the trainee
explains verbally that the exhalation valve cover must be removed in
order to check for foreign material). To score, circle a “yes” arrow
for each correct operation performance or decision; circle a “No” arrow
for each inadequate or incorrect response. The total number of circled
“Yes” arrows in the “Performs Operation Correctly” column will be the
Operations Performance Score. The total number of circled “Yes” arrows
in the “Makes Correct Decisions” column will be the DecisionMaking Score.
The maximum possible number for each score is 29.
Discuss scores with each trainee. Have trainee sign and date checklist,
together with evaluator’s signature.
File checklists for future reference.
Retest if a trainee fails to sufficiently pass checklist requirement.
Report the range of scores for only the Operations Performance Score
on the “Training Certifications and Information” section of the Disaster
Site Worker Course #7600 Outreach Training Report. FROM will be the
lowest Operations Performance Score obtained by any student and TO will
be the highest Operations Performance Score.

1. Examine the face piece for:
Excessive dirt.
Cracks, tears, holes, or distortion from improper storage.
Inflexibility (stretch and massage to restore flexibility).
Cracked or broken air-purifying element holder(s), badly worn
threads, or missing gasket(s) (if required).

harness for:
Breaks.
Loss of elasticity and twists.
Broken or malfunctioning buckles and attachments.

examine valve for:
Foreign material, such as detergent, residue, dust particles,
or human hair under the valve seat.
Cracks, tears, or distortion in the valve material.
Improper insertion of the valve body in the facepiece.
Cracks, breaks, or chips in the valve body, particularly in the
sealing surface.
Missing or defective valve cover.
Improper installation of the valve in the valve body.
4. Examine air-purifying elements for:
Correct cartridge, canister, or filter.
Correct/incorrect installation, loose connections, missing or
worn gaskets, or cross-threading in holder.
Expired shelf-life date on cartridge or canister.
Cracks or dents in outside case of filter, cartridge, or canister.

5. Attach neck strap.
6. Place chin in chin cup and pull
crown straps or head harness across head.
7. Adjust straps to correct fit.
8. Perform positive pressure user seal
check by placing palm of hand over exhalation valve cover and exhaling
slightly for a count of 10. Notice any leaks.
9. Perform negative pressure user seal
check by placing palms of hands over filter intakes and inhaling slightly
for count of 10. Notice any leaks.
10. Readjust straps, if necessary.
11. Repeat steps 8 and 9 if readjustment
occurs.
12. Check for good breathing.
13. Loosen straps from top to bottom.
Be gentle so as not to damage elasticity of straps.
