VISION 2 Face Mask

Operating and Maintenance Instructions

WARNING:
The Vision 2 is designed for use by personnel who are familiar with workplace hazards.
This leaflet must be read together with the filter leaflet prior to using the equipment.
Fit only Protector filters that conform to EN141, 143, 371 or 372, and which are suitable for
hazards that may be encountered. Using another manufacturer's filter could reduce the level of
protection normally provided by the Vision facemask and invalidate all approvals. Protector can
also advise on the suitability of filter types.
DO NOT use Vision facemasks in confined spaces, oxygen deficient atmospheres or where
there is an immediate hazard to life or health.
DO NOT use if the mask or filter is damaged, the filter is clogged, or time expired (see filter
label).
Change the filter if contaminant can be smelled or tasted, or if the canister is clogged. Filter life
depends on the density of contaminant in the atmosphere, wearer work rate and heart/lung
efficiency.
DO NOT use Vision 2 in environments that are outside its safe working temperature of -10 to
+50°C.
It is unlikely that the requirements for leakage will be achieved if hair, spectacle side arms or
clothing intrude into the faceseal.
DO NOT modify facemasks as this will invalidate all approvals and endanger wearer life and
health.
DESCRIPTION
Vision 2 is a full facemask that conforms to EN136 Class 2. It has a nominal protection factor of 2000
and an assigned protection factor of 40, or 20 when used with gas filters (Ref BS 4275 : 1997). There
are four versions of the mask:
• Two single filter versions that take DIN 40 screw-in filters: RFF1000, which has a front filter
fitting, and RFF 4000, with the filter on the right of the visor. Both types use EC200 filters.
• Two twin filter versions: RFF2000, for use with RF400 or RF600 filters.
Filters must not exceed 500 gm (Total weight).
The face seal, five point headharness and neckstrap are silicone elastomer. The coated polycarbonate
visor meets the impact requirements of EN166, Grade B.
The inner mask, with a speech diaphragm, reduces carbon dioxide dead space and minimises visor
misting. The maximum weight of the mask, without filters is approximately 630 grams.
When a wearer inhales, contaminated air is drawn in through the filter and inhale valve, over the inner
surface of the visor (keeping it clear of misting) and into the inner mask through inlet valves. Exhaled
air flows out of the inner mask through the exhale valve to the atmosphere.
Vision 2 is easily dismantled for repair and servicing, requiring only a pozi-drive screwdriver to undo
the front fitting.
USING VISION 2
1. Check that the facemask, inhale and exhale valves and head harness are clean and undamaged.
2. Check that the filter(s) fitted to the mask is not clogged or time expired, and are suitable for the
hazards that may be encountered. If necessary fit a new filter(s). Check that a filter seal(s) is in
place and is in good condition. Replace if necessary.
