2. Remove the breathing valve from the facemask.
3. Remove HUD from inside the facemask.
NOTE! SMALL LUGS PROTRUDING ON THE INSIDE OF THE VISOR (ONE ON EACH SIDE) SECURE THE HUD INSIDE
THE MASK.TO REMOVE THE HUD, GRASP THE HUD ON ONE SIDE (RIGHT OR LEFT) AND GENTLY PULL THE HUD
TOWARDS THE MIDDLE OF THE MASK. WHEN THE HUD IS PAST THE INSIDE EDGE OF THE LUG ON THE INSIDE
OF THE VISOR, THE HUD WILL BE FREE TO LIFT UP AND OUT OF THE FACE MASK.
4. Prepare a solution of hospital grade cleaner/disinfectant, i.e.: Georgia Steel
FG350 Fresh Gear cleaner/disinfectant or equivalent, using warm (approximately
100 degree F) water. If needed, Georgia Steel FK260 Heavy duty detergent may
be used for pre-cleaning to remove common industrial debris from masks prior to
disinfecting. As an alternative, Interspiro p/n 32447-05 BA Manual Cleaner 5L is
recommended. Interspiro p/n 33535-01 BA Wipes 9-pack (50 wipes per pack)
is a cleaner/ disinfectant and should be used after the Interspiro BA Cleaner for
disinfection of the facemask.
5. The mask should be submerged and scrubbed using a soft bristled brush. In
addition to scrubbing the outside surface of the face mask, the inside sealing
surfaces of the face mask that touch the face should also be scrubbed using a
soft bristled brush. The inside of the visor should not be scrubbed as this could
adversely affect the anti-fog coating. To ensure complete disinfection, refer to the
respirator cleaner manufacturers instructions.
6. Rinse the face mask well in clean water. Detergent residue may cause rubber
components to “gum” up.
7. Dry the mask using a soft towel. Ensure that excess water is removed from the air
channels and sealing edges and perform a visual inspection of the face mask
before reassembly.
CAUTION! ALCOHOL OR PRODUCTS CONTAINING ALCOHOL MUST NOT BE USED FOR CLEANING OF THE FACE
MASK OR OTHER RUBBER BASED MATERIALS.
8. If it is deemed necessary to clean the demand valve and/or regulator, care
must be taken to prevent water from entering either of these components. Do not
submerge the breathing valve or the HUD. The outside of the breathing valve
can be cleaned with a damp cloth and warm water. The outside of the HUD can
be cleaned and disinfected using a cloth dampened with the same cleaner/
disinfectant used for the face mask.
