SCOTT HEALTH & SAFETY VISION 2 Instrucciones De Funcionamiento página 3

VISION 2 users must be familiar with workplace hazards prior to using the equipment and must be fully
trained in the use of the apparatus.
This Manual must be read in conjunction with the filter Manual prior to using the equipment.
This product must only be used with SCOTT-branded filters manufactured by Scott Health and Safety
Limited. The use of any other filters will negate the approval and will be likely to reduce the level of
protection provided.
Change the filter if contaminant can be smelled, tasted, or if the canister is clogged. Filter life depends
upon the density of contaminant in the atmosphere, wearer work rate and heart/lung efficiency.
DO NOT use VISION 2 in confined spaces, oxygen deficient atmospheres (<19.5%), oxygen enriched
atmospheres (>23%) or where there is an immediate hazard to life or health.
DO NOT use if the ambient temperature is outside of the range -10°C to +50°C. Humidity levels up to 95%
RH do not present any operational problems.
DO NOT use if the mask or filter is damaged. DO NOT use if the filter is clogged or time-expired (see filter
label).
Protection will only be obtained if the unit is fitted correctly.
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 may result in death or injury to the
wearer.
INTRODUCTION
VISION 2 is a full facemask that conforms
to EN 136 Class 2, 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 two versions of the mask:
•
RFF1000 - which has a front filter
connection with a standard thread
that conforms to EN 148-1.
•
RFF4000 - which has a filter
connection on the right-hand side of
the visor, with a standard thread, in
conformance with EN 148-1.
Both versions accept a single filter from
the EC200R Series.
Note:
When fitted, the total filter weight must
not exceed 500 grams.
WARNINGS
There are three size versions of each
mask:
medium/large (M/L), with an option of
standard head harness or Polynet (PN).
The faceseal and neckstrap are silicone
elastomer and the headharness is of
EPDM. The coated polycarbonate visor
meets the impact requirements of EN
166, Grade B.
The inner
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.
