3M Ultimate FX Full Facepiece Reusable Respirator FF-401, Small

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
