P/N 89332-01 Rev F 7/11
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 be-
ing 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 face-
piece, must achieve a Fit Factor of at least 500 for Type C Pressure-Demand
Supplied Air Respirator mode of operation for use with their assigned face-
piece 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 INSTALLATION
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 PER-
FORMED, DO NOT USE THE RESPIRATOR OR ENTER THE HAZARDOUS
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.
