3M Ultimate FX Full Facepiece Reusable Respirator FF-402 Medium > 70071510807

Fully loosen all six head straps. Hold the front of the facepiece with one hand and the straps/comfort cradle away from the facepiece with the other hand, creating an opening for the head. Pull the respirator assembly down over the head. Place the nose in the nose cup and chin in the chin cup area then press the facepiece firmly and evenly against the face. While holding the facepiece in place, pull the straps over your head. Tighten the two bottom straps. Tighten the two middle straps, then the two top straps. Make sure the back of the harness is centred on the back of the head. Repeat steps 3 and 4 twice - once to position and second to secure the facepiece seal. Remove the exhalation valve cover. Place the palm of your hand over the exhalation valve and exhale gently. If the facepiece bulges slightly and no air leaks are detected between the face and the facepiece, a proper seal cheque has been obtained. If faceseal air leakage is detected, reposition the respirator on your face and/or readjust the tension of the straps to eliminate leakage and recheck seal. Replace exhalation valve cover. If you cannot achieve a proper seal, do not enter the contaminated area. See your supervisor. Place the palms of your hands over the cartridges and inhale gently. The facepiece should collapse lightly. If air leaks between the face and the faceseal of the respirator, reposition it and adjust the straps for a tighter seal. If you cannot achieve a proper seal, do not enter the contaminated area. See your supervisor. Squeeze filter covers with hands toward facepiece to restrict airflow. Be careful not to disturb the position of the respirator. Inhale gently. The facepiece should collapse slightly. If air leaks between the face and the faceseal of the respirator, reposition it and adjust the straps for a tighter seal. If you cannot achieve a proper seal, do not enter the contaminated area. See your supervisor.
