should be stored away from direct
heat and sunlight, and operated between
-15°C and +60°C. Prior to storing in very
low temperatures the apparatus,
especially the valve flaps, must be
completely dry.
2.2 HOOD
The hood is fabricated in high-visibility,
flame-resistant PVC or PVC coated
materials with a rubber neck seal.
An inner mask, which covers the wearer’s
nose and mouth, minimises visor misting
and carbon dioxide dead space.
Sprung metal strips hold the visor flat
when in storage and when the hood is in
use; form the hood to a shape that holds
the inner mask against the wearer’s face.
A sealed foam pad on the inner rear of
the hood holds the hood in place when
the wearer’s head moves.
The spring-loaded exhale valve helps
maintain an above ambient pressure
within the hood.
2.3 REDUCER/CYLINDER
VALVE
The reducer/cylinder valve (RCV) is
screwed permanently into the cylinder. It
is a spring and piston device with a fixed
orifice outlet. The cylinder valve opens
automatically when the firing pin is pulled,
permitting air to flow from the reducer to
the hood.
The quick-fire strap can be used to pull
the firing pin in the unlikely event of the
pin not releasing when the bag is opened.
The red
EMERGENCY PULL
disc on the RCV
can be used to pull the valve actuator
once the firing pin has been released.
The warning whistle sounds when the
designed duration (10 or 15 minutes.) is
reached. Beyond this point the carbon
dioxide level in the hood increases and
the hood must be removed as soon as
the wearer is clear of the hazard area.
The medium-pressure system is
protected from over-pressurisation by a
pressure relief valve (PRV) located in the
reducer.
The contents gauge indicates the cylinder
charge level, which must be maintained
at fully-charged with the needle in the
green sector of the gauge.
The orange sector of the gauge indicates
the minimum cylinder charge that will
achieve the specified duration.
This is
NOT an acceptable charge state for
issued or ready-use apparatus.
The charging adaptor conforms to prEN
144-2 : 1996.
