Depends on the type of mask used, but if it is a light paper/fabric mask, place the metal wire edge of the mask over the bridge of your nose, bend the wire gently by pressing with your fingers, make sure the edge fits the contours of your nose and you can see normally; if the mask is pleated you should now roll the mask down over your mouth; and finally adjust straps behind head/ears (depending on the model). The mask should not bulge or rise unintentionally; re-adjust the wire edge if necessary.
For the hard plastic type of masks with rubber/silicone edging, put on the mask and inhale lightly through your nose; if the mask tightens on your face and no air flows in the mask from the sides, it should be tight. Adjust the straps so the mask sits firmly on your face but not too tight to prevent pressure injuries.
Always check the manufacturer's instructions first, if working in a dangerous environment.
