Conducting a Fit Test
Before you conduct a fit fest, be certain you have read the Operation
and Daily Check chapters.
Conduct a Fit Test as follows:
1. Instruct the user to put on the respirator five minutes before the fit
test starts to purge the particles trapped inside the respirator and
permit the wearer to make certain the respirator is comfortable.
Have the subject don the respirator without assistance. Fit test
results depend on the subject knowing how to properly don the
respirator. Train all subjects in proper respirator-donning
techniques before being fit tested. DO NOT allow the subject to
adjust the respirator during the exercises, as this invalidates
previous exercise results.
If testing a disposable filtering facepiece respirator, have the fit-
test subject hang the tubing support neck strap around his or her
neck, adjusting it to a comfortable position. Position the tubing
support neck strap so that the tubing does not pull the respirator
off the person’s face. Have the person tilt his or her head up and
down, turn side to side, and bend over to see if the tubing pulls
the respirator away from their face. If it does, readjust the neck
strap or the tubing and repeat check the fit again.
