CleanSpace HALO - Cleaning Full Face Mask

29
WARNING
The Steri-Plus and HALO BIO Exhalation Filters (CS3039 and CS3027) are electrostatic filters and
their performance will be degraded by exposure to certain organic solvents including
isopropanol (IPA), xylene and toluene. Always remove the Exhalation Filter before cleaning the
mask. If there is a possibility that the Exhalation Filter has become contaminated with any
solvent, replace it.
WARNING
Never dry the mask or exhalation valve with a cloth that may leave behind lint. Lint
contamination of the exhalation valve may cause it to leak, resulting in overexposure to
contaminants and lead to sickness or death.
CLEANING THE FULL-FACE MASK
The full-face mask harness can be left attached to the mask. Carrying out the following steps prior to cleaning the
mask improves access.
1. Remove the orinasal piece – Pinch the two orinasal piece snaps together and pull the top of the orinasal
back. Withdraw the orinasal piece from the main mask. See Figure 29.
2. Raise the rain cover. See Figure 30.
Figure 29 – Remove inner mask
Figure 30 – Raise rain cover
Once this is complete, the full-face mask can be cleaned using two methods.
1. Non-Alcohol Disinfectant or Cleaning Wipes
•
Non-alcoholic cleaning wipes are impregnated with benzalkonium chloride, a bactericidal solution ideally suited
for face pieces that are going to be worn in the near term/same day. Wipes containing alcohol or more
stringent cleaning agents should be avoided if the mask is not going to be washed before being worn.
•
Clean all surfaces of the mask with a wipe, including the valve leaf.
2. Hand wash in warm soapy water
•
Wash the mask thoroughly with a mild detergent in warm water (less than 50°C).
•
A soft brush or sponge can be used to remove any stubborn dirt or grit.
•
To clean the exhalation valve, gently wash the warm water solution through the valve from the inside and use a
sponge to gently clean the valve surfaces. Remember to lower the rain cover again when done.
•
Rinse the mask and valve well in warm running water. IMPORTANT: If the mask is not rinsed thoroughly,
residue from cleaning solution may irritate the wearer’s skin or cause the valve to stick.
Drying the mask
After cleaning, allow the mask to air dry in a clean environment, valve up to prevent water pooling. The
mask can also be hand-dried with a clean, lint- free cloth. IMPORTANT: Cleaning can cause the
exhalation valve leaf to stick. Before use, check that the exhalation valve leaf operates freely by gently
lifting the valve. Do not dry the mask by exposing directly to heat i.e. hair dryers or heaters.
WARNING
Never dry the mask or exhalation valve with a cloth that may leave behind lint. Lint contamination
of the exhalation valve may cause it to leak, resulting in overexposure to contaminants and lead
to sickness or death.
