What is a User Seal-Check?
The seal check is done by the wearer each and every time after donning a respirator in order to assure that the respirator is fully “sealed” to the face prior to entering a contaminated work area. The user seal check in and of itself does not obviate the fit-test outlined above. The check consists of inhaling forcefully once the respirator is donned and seated in the optimal position. Suction should be felt on the inside portion of the facepiece much like when sucking on an empty bottle. The facepiece should partially indent/collapse from the resultant negative pressure thusly generated. If this is not achieved, then press firmly around the circumference of the Fitseal™ respirator to assure that the adhesive fully contact the face, and then repeat the seal check. Repeat the procedure until a proper seal is obtained. If unsuccessful, then discard the respirator and take another.
