2. TECHNICAL
DESCRIPTION
2.1 GENERAL
FLITE is a positive pressure compressed
air, airline, breathing apparatus (BA). It
can be used with either:
(a) A compressed air cylinder to
enable wearers to leave hazardous
areas safely in the event of airline
failure, or
(b) A facemask that can be fitted with a
suitable Scott Safety particulate
filter, to be used when entering or
leaving the hazard area with the
airline disconnected.
In the latter mode the facemask functions
as a negative pressure device.
The supply airline hose connects to a
CEN connector that supplies the
facemask-mounted demand valve via a
length of medium pressure air hose.
WARNING:
FLITE must not be used in oxygen
deficient atmospheres whilst
disconnected from the airline supply
and with the cylinder not in use.
Non Return Valves (NRV) in the
pneumatics seal the air inlet from the
airline and the cylinder when either are
not in use. The apparatus MUST be used
with a cylinder, or an airline, or both.
The apparatus comprises a full facemask,
a Demand Valve (DV), and a pigtail with
CEN coupling for attaching the supply
airline.
There are three cylinder options that can
be provided with the apparatus.
The air supply specification for FLITE is
detailed below:
Air Supply Specification
The flame-resistant bandolier relieves the
pull of the airline hose and when a
compressed air cylinder is fitted, supports
the cylinder bag.
FLITE is marked in accordance with EN
139 and AS/NZS1716 : 2012. An
explanation of those markings is given
below:
2.2 FILTERS
The service life of the filters is dependent
upon the environment and the use-by-
date marked on the filter. DO NOT use
damaged, wet, clogged, or time expired
filters.
The filter screws directly into a threaded
connector on the facemask. A filter cover
is provided to preserve the filter when an
airline is in use. A blanking plug is
provided to seal the mask when a filter is
not fitted. Filters must conform to EN 141
or EN 143 with an EN 148-1 standard
thread and must be appropriate for the
known workplace hazards.
