B. HOW TO DON THE RESPIRATOR
WARNING
Always read cartridge labels prior to use to be certain that you have
cartridges and/or filters that will provide the required protection. Filters
labeled for protection against particulates only shall not be used for
gases/vapors, and cartridges labeled for protection against gases/vapors
only shall not be used for particulates. Both cartridges/filters must be
of the same type. The failure to comply with this warning may lead to
personal injury, illness, or death.
1. Inspect the respirator as described in section G.
2. Install cartridges/filters onto the inlet ports. Hand tighten, but do not
overtighten. See inset 1.
3. Position the bottom of the facepiece as low as possible under the chin while
positioning the narrow portion of the facepiece on the bridge of the nose.
Position the cradle headband above the ears so that it straddles the crown
of the head. See inset 2.
4. Hook the lower headband straps below the ears and around the back of
the neck. Adjust the upper headband by pulling both straps at the same
time. Adjust the lower headband straps in the same manner. Adjust the
headbands for a leak-tight fit, but do not overtighten the straps. See
inset 3. For the Blue 1 respirator, you must remove the respirator to
adjust the headband strap slides as necessary for a leak-tight fit, but do
not overtighten the straps.
5. Perform a fit check before using the respirator.
