Appendix G Facepiece Fitting; About Fit Testing - 3M SCOTT AIR-PAK X3 PRO Operating & Maintenance Instructions

A respirator quantitative fit test must be performed to ensure the correct respirator facepiece size has been selected
and assigned to the user. The respiratory protection's program manager or safety coordinator is responsible for
assisting the user in selecting the correct respirator size relative to the user's facial features and dimensions. Any
approved 3M Scott Fire & Safety accessories that will be used with the respirator, such as a communications device
installed on the facepiece, must be in place during fit testing. If changing from a standard facepiece to a facepiece
with an installed accessory, such as a communications device, it is recommended that a new fit test be performed.

About Fit Testing

Before occupational use of this respirator, a written respiratory protection program must be implemented meeting all
local, state, and federal government requirements. In the United States, employers must comply with OSHA 29 CFR
1910.134, which includes medical evaluation, training, and fit testing.
Respirator fit tests are explained fully in the following:
•
American National Standard Respiratory Fit Testing Methods, ANSI/AIHA/ASSE Z88.10, current edition, which is
published by the American National Standards Institute (ANSI), 11 West 42nd Street, New York, New York, 10036
•
Occupational Safety and Health Standards, OSHA 29 CFR 1910.134 Appendix A, which is published by the
Occupational Safety and Health Administration (OSHA), 200 Constitution Avenue, NW, Washington DC, 20210.
Quantitative fit testing per OSHA Standard 29 CFR Part 1910.134 Appendix A, or ANSI/AIHA/ASSE Z88.10,
current edition, requires testing in the negative pressure mode using Quantitative Fit Test (QNFT) protocols
deemed acceptable by those standards. For quantitative fit testing, 3M Scott Fire & Safety facepieces require use of
the appropriate negative pressure QNFT test protocol, such as the ambient aerosol condensation nuclei counter (for
example, the PortaCount
