1.4 APPARATUS DURATION
All durations quoted are nominal, based
on an Average Wearer Consumption
Rate of 40 litres/minute and FULLY
CHARGED cylinders. Actual Wearer
Consumption rates vary due to many
factors, such as:
1. Workload: high work rates increase
consumption rates.
2. Weight of apparatus and use of
heavy or restrictive clothing.
3. Work environments with extremes
of heat or cold.
4. Physical fitness of the wearer.
5. Other factors include emotional
stress and fatigue.
It is important that all wearers are aware
of these factors and take account of them
when assessing cylinder duration.
The Total Duration for the apparatus is
calculated to be 15 minutes for 200 bar
cylinders and 20 minutes for 300 bar
cylinders based on a free air capacity of
600 or 820 litres and an Average Wearer
Consumption Rate of 40 litres/minute.
The Warning Period is calculated to be 5
minutes based on a 68 bar whistle and a
3 litre cylinder.
The Nominal Duration for the apparatus
is therefore 10 or 15 minutes.
1.5 PERSONNEL TRAINING

2. TECHNICAL
DESCRIPTION
The CEN-PAQ is a waistcoat-mounted,
short duration, self-contained breathing
apparatus.
The apparatus is available in two
versions, a standard SCBA version and
an airline version.
The airline version is fitted with a
waistbelt-mounted manifold allowing the
apparatus to be supplied from a
breathable compressed airline supply.
The apparatus is certified to European
Standard EN 137 for self-contained
breathing apparatus and EN 139 for
airline apparatus and has been issued
with a 'CE' mark.
The apparatus comprises a waistcoat, a
high-pressure air cylinder, two stage
pneumatic system with pressure reducer
and demand valve; and a facemask.
The facemask-mounted, high
performance demand valve ensures that
positive pressure is maintained within the
facepiece, thus providing the highest
degree of respiratory protection.
For airline apparatus, a medium
pressure, compressed airline supply is
connected to a waistbelt-mounted
manifold, thus supplying air directly into
the medium pressure port on the
pressure reducer.
A 3-litre water capacity, 200 or 300 bar
cylinder which provides a free air capacity
of 600 or 820 litres is mounted in a pouch
on the back of the jacket. This allows a
total duration of 15 or 20 minutes when
used at an average wearer consumption
rate of 40 litres/minute, (please refer to
Section 1.4 - Apparatus Duration for
further details).
The apparatus utilises a waistcoat
fabricated from either a high visibility
P.V.C. or a black, anti-static material.
The standard apparatus features a
double-breasted Velcro
TM
fastening
waistcoat whereas anti-static and airline
versions feature a double buckle closure.

CEN-PAQ
4
The high visibility waistcoat MUST NOT
be used in potentially explosive or
flammable atmospheres.
The waistcoat is designed to fit a wide
range of body sizes with the minimum of
adjustment.
The alloy steel cylinder has a brass
cylinder valve with a handwheel. A safety
lock on the handwheel prevents
accidental valve closure. The cylinder is
retained in the pouch by a tough, dual
action buckle.
2.1 PNEUMATICS
High-pressure air from the cylinder is
connected through the cylinder valve and
a length of high-pressure hose to a
pressure reducer. A sintered filter in the
connector prevents the ingress of dirt and
debris.
A high-pressure hose from the reducer
supplies air to the shoulder-mounted
pressure gauge and warning whistle
assembly. The gauge dial has photo-
luminescent markings to improve low-
light legibility. The gauge is protected by
means of a rubber shroud.
The warning whistle operates at 68 bar,
when there is at least 200 litres of air left
in the cylinder, giving a warning period of
5 minutes when consumed at 40
litres/minute (please refer to Section 1.4 -
Apparatus Duration for further details).
The high-pressure hose has a minimum
burst pressure of 800 bar.
2.2 REDUCER
The pressure reducer operates on a self-
regulating, spring-loaded piston principle
that is completely automatic in operation
and requires no adjustment.
A restrictor within the reducer body
prevents air loss in excess of 25 litres per
minute should the gauge, whistle or hose
become damaged.
A pressure relief valve prevents over-
pressurisation of the medium pressure
breathing circuit.
An outlet pressure of between 5.0 and
11.0 bar from the reducer is supplied to
the facemask-mounted demand valve.
2.3 DEMAND VALVE
Air from the reducer is connected through
a reinforced chlorinated polyethylene
hose to the facemask-mounted DV,
which regulates the air supplied to the
wearer.
The DV operates in conjunction with the
facemask spring-loaded exhale valve to
maintain a positive pressure within the
facemask.
The DV has a servo-assisted tilting
diaphragm mechanism that responds to
pressure changes within the facemask to
regulate the flow of air to the mask,
ensuring that pressure within the mask
remains safely above ambient.
The DV has a reset button that enables
wearers to close the airflow through the
DV, permitting the facemask to be
removed during test procedures and at
the end of a task, without loss of cylinder
air.

CEN-PAQ
5
When the apparatus is donned, the DV is
normally “reset” (closed) and is opened
(activated) when the wearer takes a first
breath.
The DV has a supplementary flow device
(bypass), that the wearer can open using
the bypass knob.
When the bypass is used the unregulated
flow of air through the DV reduces
cylinder duration.
The DV is connected to the facemask by
a Quick-Fit (QF) bayonet fitting with a
spring-loaded locking catch to prevent
accidental disconnection.
2.4 FACEMASK
CEN-PAQ is approved for use with the
PanaSeal facemask. The PanaSeal
facemask is made from non-dermatitic
materials and is available in either black
neoprene or blue silicone and is retained
using a fully adjustable five-point head
harness.
The mask is approved to EN 136 for use
with positive pressure breathing
apparatus.
A speech diaphragm aids
communication.
The mask incorporates an inner mask
that reduces carbon dioxide 'dead space'
and prevents visor misting.
The polycarbonate visor meets the
requirements of EN 136, Part 10, for
impact resistance and optical clarity.
A version of the PanaSeal facemask is
also available for use with the Gallet
TM
helmet.
For airline equipment, the maximum
allowable length of supply hose is 90
metres.
3. QUALITY
