Operating Instructions
V. OPERATING INSTRUCTIONS
A. Recommended Usage
Nextteq recommends the following in regards to use of VeriFit Irritant
Smoke Generators:
1. Qualitative Respirator Fit Testing be performed at the following
intervals:
a. At time of initial respirator selection and fitting
b. Annually after the initial fit testing or other successful
qualitative fit test
c. Whenever the respirator becomes “unacceptable” to the
employee and the employee properly notifies the employer
of the condition. A respirator may be unacceptable if it
causes irritation or pain to the employee or if because of
discomfort the employee is unable to wear the respirator
for the time required.
2. After being checked by the test administrator, the test subject
should wear the respirator for approximately 10 minutes before
starting the fit test.
3. The test subject should not be requested to make any head or
facial movements until after the following has occurred:
a. The smoke generator has been brought within the OSHA 29
CFR 1910.134 specified distance from the test subject.
b. The smoke has been delivered.
c. No leakage of the respirator has been detected. At the
time the test administrator starts to deliver smoke to the
test subject and at the time the test subject is requested
to commence making head or facial movements, the test
administrator should be extremely alert and aware of any
slight indication of the test subject’s reaction to the smoke.
