1. Cup the respirator in your hand, with the nosepiece at your fingertips, allowing the headbands to hang

freely below your hand.

2. Position the respirator under your chin with the nosepiece up. Pull the top strap over your head resting it

high at the top back of your head. Pull the bottom strap over your head and position it around the neck

below the ears.

3. 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.

! Pinching the nosepiece using one hand may result in improper fit and less effective respirator

performance. Use two hands.

4. Perform a User Seal Check prior to each wearing. To check the respirator-to-face seal, place both hands

completely over the respirator and exhale. Be careful not to disturb the position of the respirator. If air

leaks around nose, readjust the nosepiece as described in step 3. If air leaks at the respirator edges, work

the straps back along the sides of your head. If you CANNOT achieve a proper seal, DO NOT enter

the contaminated area. See your supervisor.

over head. Still holding respirator in position, pull top strap over head and remove respirator.
