FACEPIECE FITTING
30 P/N 595390-01 Rev D 202009
CBRN SCBA or APR
If you are fit testing for CBRN SCBA Open Circuit mode of operation (minimum fit factor equal to or greater than 500
minimum) or CBRN APR (minimum fit factor equal to or greater than 2000 minimum), appropriate negative pressure
testing equipment must be used. For example:
•
If you are fit testing for CBRN SCBA Open Circuit or CBRN APR, use a P100 Filter (P/N 052683) and Fit Test
Adapter (P/N 201520-01).
•
If you are using a facepiece that has been specially modified for a fit testing program such as that described in
NIOSH Procedure No. RB-CET-STP-CBRN-0352, Determination of Laboratory Respirator Protection Level
(LRPL) Quantitative, Medium Flow, Deep Probe, Corn Oil, Fit Factor Performance Test For Chemical, Biological,
Radiological and Nuclear (CBRN) Full Facepiece Respiratory Protection Devices (RPD) Standard Testing
Procedure , install the appropriate filtration element directly into the 40 mm facepiece adapter.
Fit Testing Procedure
Negative Pressure User Seal Check
The size and style facepiece must be selected based on the user’s measured face size. For the initial fitting of the
facepiece, conduct a negative pressure User Seal Check as described in step 16 of the “ Donning the Facepiece ”
section of the User Instructions provided with the respirator. Follow the procedure carefully. If the selected facepiece
does not pass the negative pressure User Seal Check or does not fit securely without movement in the chin or chin
cup area, or if the user experiences discomfort in the chin or throat, try the next nearest size, larger or smaller. After
passing the negative pressure User Seal Check, the facepiece size selected must be verified by successfully passing
a respirator fit test.
A leak that is detected from a location other than the face-to-facepiece seal may indicate damaged or defective
equipment. Remove the defective equipment from service and tag it for repair by authorized personnel. Repeat the
testing with equipment known to be operating properly.
Quantitative Fit Testing
Before fit testing, test subjects must pass a medical evaluation and be in good health. Any and all conditions that might
interfere with a good face-to-facepiece seal must be addressed and corrected before performing the fit testing.
To verify the fit factor of the respirator, testing must be performed to local, state, federal or government jurisdiction
having authority following established protocols.
Fit test exercises must be performed as if the respirator is being used in a hazardous atmosphere. Users must not
bump the facepiece, filter, or adapter into the body through exaggerated motions. Users must not talk except when
directed to by the test administrator.
3M Scott requires that users of 3M Scott Fire & Safety respirators and facepieces must achieve a fit factor of at least
500 for CBRN SCBA (Open Circuit) use or at least 2000 for CBRN APR use with their assigned facepiece style and
size using the fit test procedures and exercise regimen stated above. If a fit factor of at least 500 for CBRN SCBA
(Open Circuit) use or at least 2000 for CBRN APR use cannot be achieved with any facepiece size or style, the user
must not use this respirator.
If the respirator user passes a negative pressure User Seal Check but does not pass a respirator quantitative fit test,
try the next nearest size, larger or smaller and repeat the negative pressure User Seal Check and the quantitative fit
test. If an air leak is still detected, either per these User Instructions or the fit testing process, the use of Mask Seal Kit
P/N 805655-01 may be required to attain a proper fit. Refer to the Mask Seal Kit Installation and Use Instructions
(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. If an air leak is still detected, do not use the respirator.
