Troubleshooting

Failure to reach challenge pressure
Like the large leak, when the traceline does not reach the challenge pressure line, this indicates
that there is a moderate leak between the QuantiFit2 and the person wearing the respirator.
1.
Check all tubing connections for secure attachment and confirm there are no holes or tears.
2.
Check to ensure that the QuantiFit2 respirator adapter is properly attached to the respirator.
Look for cross-threading, loose connection, etc.
3.
Check respirator for proper tightness to the face and check that no hair, beard stubble, unique
face characteristics, or other objects inhibit a good face-to-facepiece seal.
4.
Try a different respirator. Many respirators
seem
to fit well but are not properly sized to a specific
wearer. In other cases, a different size or style may be better suited for the individual wearer.
Perfect graph but still fails
When the graph looks like a perfect fit test, but the fit factor is too low to pass, this means that
there is a leak, but it’s not a huge leak. This would be
related to a leak in the integrity of the
respirator, a poor donning, the fit of the respirator, a fault in an adapter, or a dirty exhalation
valve in the respirator. Be sure to clean the exhalation valve with a moist wipe. As in other
leakage situations (see HIGH LEAKAGE), check all tube connections, adapters, and adapter
connections to respirators.
1.
Check for proper tension of respirator to face.
2.
Try a different size or different respirator.
3.
Check fit test adapter for leaks. Check Troubleshooting section 3. Adapter Fault below. OHD
provides this as an optional service during yearly calibration
