AIRSHIELD
-11-
MAINTENANCE AND CARE
After using the Airshield follow the procedure
below:
Airshield should not be cleaned with
compressed air, solvents, sterilising
by heat or autoclaving, as this will
cause damage.
Precautions are to be taken to prevent
inhalation of harmful dust or
contaminant on the surface or
retained on the filters.
■ Carefully remove bulk contamination from the
Airshield and wipe down with a damp cloth
containing a mild detergent solution.
■ Clean and sterilise all Airshield parts by
wiping down the visor, face seal and
headband with visor wipes (ref. AIR/WIPE)
(Sodium Hypochlorite or Ethylene Oxide Gas
have also been proved effective).
Gamma sterilisation is effective but
causes embrittlement of plastic
components and is not recommended.
Replace if deficient after the following checks:
1. Excessive abrasion and scratches on the visor.
2. The face seal for its seal to the visor and for
holes.
3. Fit and fastenings to the headband.
This manual contains relevant guidance on
routine maintenance, however, you may wish to
introduce additional checks as required by
COSHH. The following table shows the
frequency of these checks.
Operation Frequency
Clean Internally and Externally Daily
Visual Inspection Daily
Charge Battery Pack/Packs Daily
Functional Test* Daily, Weekly and Monthly
* Remarks: Dust from wood, grain and cement
may suit more frequent replacement of pre-filter
to extend the life of the main filter. No filter
should be left in the hood/helmet for more than 1
month if in daily use or 3 months if used
infrequently.
Monthly - All items checked and signed by
Operator.
Quarterly - All items checked and signed by
Supervisor.
■ Release the cover by lifting the left and right
lower sides to disengage the lugs then pull
forward and lift.
■ Remove the pre-filter and main filter as
described. Dispose of in accordance with
local health and safety regulations.
■ Remove battery pack(s). Ensure battery pack
is clean and recharge.
■ Wipe down with a damp cloth containing a
mild detergent solution to remove any loose
dust from inside the cover. Do not apply
pressure to the fan blades, to clean use a soft
brush.
■ Fit replacement pre-filter and main filter.
■ Fit fully charged battery pack/packs.
■ Operate the switch to check the function of
the fan-motor unit.
■ Carry out the functional test.
Scratched or damaged oculars (visor)
may not offer full protection and
therefore should be replaced.

disinfection of visor
