2 Introduction and Overview
Why Fit Test
There are two primary reasons for respirator fit testing:
•
Verification of Training. After the individual has received respirator
training, a fit test checks that the person has learned how to properly put
on and wear a respirator without assistance.
• Sizing. It is important to make sure that the individual is issued a
respirator that is capable of providing protection when worn properly,
that is, it is the right size.
Preparations for Fit Testing
Training the Trainer
The person conducting the fit test must have a clear understanding of
respiratory protection, respirators, and fit testing to be effective. Anyone
can master the operation of the P

simply by studying this manual, but the background knowledge required
to proficiently fit test cannot be obtained from here. Consider attending
a one-, two- or three-day seminar on fit testing provided by various
consultants. Contact TSI for references.
Respirator Training
Respirator training is critical for any respiratory protection program. All
employees who wear respirators must be taught how and why they are
used. This training should be done prior to the fit test, not during the fit
test. Consult the regulations or standards that pertain to your industry
for information on training requirements. The P

Precautions for Fit Testing
The following is a discussion of several precautions that should be
considered prior to conducting a fit test:
Fit Testing People Who Smoke Cigarettes or Cigars
Smokers exhale particles for at least 30 minutes after they have smoked
a cigarette or cigar. The P

C
OUNT

P

fit tester can count these
particles and will interpret them as if they were caused by face seal
leakage. It is very important to instruct individuals not to smoke for at
least 30 minutes prior to fit testing. Fit factors for anyone who has
smoked recently will be lower than that individual deserves and may
even cause him or her to fail the fit test entirely.
