Place the mask in the palm of your hand with the nose clip closest to your fingers and the mask opening facing you. Starting with the lower headband first, pull each headband up and over your hand, one at a time.
Position the mask on your face with the bottom of the respirator under your chin. Pull the bottom headband over your head and bring it around your neck, below your ears. Then, pull the top strap up and rest it high at the top of your head.
Place your fingertips from both hands at the top of the metal nosepiece. Using two hands, mold the nose area to the shape of your nose by pushing inward while moving your fingertips down both sides of the nosepiece. WARNING: Pinching the nosepiece using one hand may result in an improper fit and less effective respirator performance.
Perform a respirator-to-face seal check before each wearing by placing both hands completely over the respirator, careful as to not disturb its position, then exhale. If air leaks around the nose, re-adjust the nose-clip as described in step 3. If air leaks at the edges around your face, work the straps back along the sides of your head. WARNING: If you CANNOT achieve a proper seal, DO NOT enter a contaminated area.
