4. Detach the air hose from the facemask and use a synthetic sponge moistened in a warn solution of
water and TriGene to clean and sanitise it.
Note: Water MUST NOT enter the hose.
5. Sponge the facemask with a synthetic sponge moistened in a warn solution of water and TriGene
to clean and sanitise it. Take care not to scratch the visor.
6. Flush the exhale valve under clean running water and check that it is in good condition.
7. Hang the mask by the head harness away from direct sunlight and high temperatures until it is
completely dry. Store it carefully to ensure that the visor will not be damaged, in a cool, clean, dry
store, away from direct sunlight.
8. Perform the leak test as described in Using T7/Vision 2, sub-section 6.
MAINTENANCE
Maintenance tasks must only be performed by trained personnel. Contact Protector for training
information. Following servicing, mask integrity can be checked using the Protector Respirator Test
Equipment. Contact Protector Internal Sales (+44 (0) 1695 711711) for details on Service Providers.
FACESEAL AND INNER MASK – During pre and post use inspections and at the stipulated
maintenance intervals, inspect for holes, surface damage or excessive distortion, particularly around the
face seal. Replace as necessary.
Fig 1
EXHALATION VALVES – These should be as new with no damage. The valves
are marked with a code indicating the year and year quarter of manufacture (see
Fig 1). The two digit number stamped on the valve is the year of manufacture.
The dot, stamped in one of the four quadrants is the quarter of the year in which
manufacture took place. Top right (in relation to the year digits) = Jan to March,
bottom right = April to June, bottom left = July to September and top left =
October to December. Exhalation valves should be replaced at least annually,
regardless of condition.
HEADHARNESS – This should be checked for possible failure, paying particular attention to the anchor
studs. The EPDM headharnesses are stamped on the outside centre, with a code indicating the date of
manufacture. The number in the centre is the year of manufacture and the dots around the outside of
the number indicate the month of manufacture during that year. Therefore the number ‘00’ with seven
dots around it is July 2000.
NOTE: REPLACEMENT INTERVALS FOR COMPONENTS MARKED WITH A DATE OF
MANUFACTURE SHOULD BE CALCULATED FROM THE DATE OF FIRST USE OF THE
COMPONENT AND NOT THE DATE OF MANUFACTURE.
