Quantitative Fit Testing (QNFT) can be conducted with 42 CFR 84 P100 type filters. To conduct QNFT
on the FR-M40 facepiece, screw a 701 Filter Adapter into the filter inhalation port in the facepiece. Next,
attach a 601 Quantitative Fit Test Adapter along with a 3M 2000 Series P100 42 CFR 84 approved filter. If
quantitative fit testing (QNFT) is utilized, a fit factor (FF) of at least 500 must be obtained. The respirator
may be used up to an assigned protection factor (APF) of 50 times the allowable exposure limit.
Qualitative Fit Testing (QLFT) can be conducted with the cartridge in place. The 3M FT-10 (sweet) or
FT-30 (bitter) Qualitative Fit Test Apparatus can be utilized to conduct the fit testing. If qualitative fit
testing (QLFT) is utilized, a passing fit factor (FF) of at least 100 is assumed. The respirator may be used
up to an assigned protection factor (APF) of 10 times the allowable exposure limit.
Doffing the Respirator (Figure 15)
fig. 15
Before removing the respirator, you must leave the contaminated area and be completely decontaminated
by following applicable decontamination protocols. Alternatively, have an individual, who has not been
contaminated, assist you with doffing.
Before storing the respirator, be sure that the respirator has been decontaminated per applicable
decontamination protocols. If necessary, dispose of the equipment per applicable waste regulations.
1.
Loosen the bottom straps of the facepiece.
2.
If this respirator is assigned to an individual user, do not loosen the temple or head straps.
Note: This will allow for quicker donning in the future as the temple and head straps will already be
adjusted for the individual user. Only the bottom straps will require major adjustment after the respirator
is donned. Temple and head straps may require only minor readjustment.
3.
Place one hand on the front voicemitter to hold the facepiece on the face. With the other hand
grasp the head harness tab and pull the head harness over the front of the facepiece.
