P/N 595189-01 Rev A 4/10
To verify the fit factor of the respirator, testing must incorporate an exercise
regimen of normal daily activities. SCOTT requires the following set of fit
test exercises, which are based on OSHA Standard 29 CFR Part 1910.134
Appendix A, and ANSI Z88.10-2001 with modifications.
Exercises are to be performed each for 60 seconds (except as noted) in
a standing position during the test:
• Normal Breathing
• Deep breathing
• Turning head side to side
• Moving head up and down (look up/look down)
• Talking (read the Rainbow Passage)
• Grimace (15 seconds)
• Bending Over (touch toes) / Reach up (toward the ceiling)
• Normal Breathing (repeat)
Fit test exercises must be performed carefully as if the respirator was being
used in a hazardous atmosphere. DO NOT bump the facepiece, filter, or
adapter into the body through exaggerated motions. DO NOT talk except
when directed to by the test administrator.
SCOTT requires that users of this respirator with an approved SCOTT
facepiece, must achieve a Fit Factor of at least 500 for Type C Pressure-
Demand Supplied Air Respirator mode of operation for use with their as-
signed facepiece style and size using the fit test procedures and exercise
regimen stated above. If a Fit Factor of at least 500 cannot be achieved
with any facepiece size or style, the user MUST NOT use this respirator.
If the respirator user passes a NEGATIVE PRESSURE LEAK TEST but
DOES NOT pass a respirator Quantitative Fit Test, try the next nearest
size, larger or smaller and repeat the NEGATIVE PRESSURE LEAK TEST
and the Quantitative Fit Test. If leakage is still detected, either per these
user instructions or the OSHA fit testing process, the use of Mask Seal Kit
P/N 805655-01 may be required to attain a proper fit. Refer to the INSTAL-
LATION AND USE INSTRUCTIONS, SCOTT P/N 89462-01, included with
the Mask Seal Kit. After installing the Mask Seal Kit, repeat the fit testing
process to confirm a proper fit.
Once the proper size is selected and assigned to the user following suc-
cessful Portacount Respirator Fit Tester testing to achieve minimum Fit
Factors required, the respirator user must perform and pass a NEGATIVE
PRESSURE LEAK TEST as described in these instructions every time the
facepiece is donned to ensure proper fit before using the respirator in a
hazardous atmosphere.
During NEGATIVE PRESSURE LEAK TESTING, any facepiece leakage
that is detected from other than the face to facepiece seal may indicate
damaged or defective equipment. Remove the defective equipment from
service and tag for repair by authorized personnel. Repeat the testing with
equipment known to be operating properly.
IF A SATISFACTORY NEGATIVE PRESSURE LEAK TEST CANNOT BE
PERFORMED, DO NOT USE THE RESPIRATOR OR ENTER THE HAZ-
ARDOUS ATMOSPHERE.
The facepiece alone does not provide any protection against a hazardous
atmosphere without the use of the complete respirator.
A respirator Quantitative Fit Test must be routinely carried out as outlined
above for each user of this respirator to determine or confirm the amount
of protection that the respirator provides.
Periodically repeating the fit testing is required to identify any physical
changes of the user (such as those listed in the DONNING PROCEDURES)
which could effect the fit of the facepiece.
