Table 2
Airline pressure must be between 5.0 and
9.0 bar (70 and 130 psi). Airflow supply
capacity for a single airline is given in
Table 2.
Generally; each additional wearer
requires an extra 150 litres per minute,

1.4 APPARATUS DURATION
All durations quoted are nominal, based
on an Average Wearer Consumption
Rate of 40 L/min and FULLY CHARGED
cylinders. Actual Wearer Consumption
rates vary due to many factors, such as:
• Workload: high work rates increase
consumption rates.
• Weight of apparatus and use of
heavy or restrictive clothing.
• Work environments with extremes
of heat or cold.
• Physical fitness of the wearer.
• Other factors include emotional
stress and fatigue.
• Supplying cylinder air to a
resuscitator or rescue second mask
(RSM).
It is important that all wearers are aware
of these factors and take account of them
when assessing cylinder duration.

2. APPARATUS
DESCRIPTION
2.1 GENERAL
Contour is an open circuit, self-contained
compressed air Breathing Apparatus (BA)
for use by fire-fighters and in industrial
applications, where a high level of
respiratory protection is required.
Standard versions of Contour feature a
mechanical pressure gauge and whistle
mounted on the left-hand shoulder strap.
Versions specifically intended for use by
fire-fighters are available which
incorporate the IRIS data-
communications system.
All safety-critical components on the
Contour Set, (for example the reducer
valve and demand valve etc), are
individually identified by a unique serial
number and date of manufacture.
Contour is approved to European
Standards EN 137 : 1993, EN 137 : 2006
Class 1 (self-contained breathing
apparatus) and EN 139 : 1995 (selfcontained breathing apparatus with airline
attachment). Contour is 'CE' marked in
accordance with EC Directive
EC/686/1986.
Contour is approved to Australian/New
Zealand Standard AS/NZS1716 : 2003.
Contour is also approved for use at sea
by:
Lloyds Inspectorate, in accordance with
SOLAS regulation 17 and the 1980
Merchant Shipping Act.
Please call Scott Health and Safety
Limited for further apparatus approval
details.
This manual contains user instructions for
single cylinder, twin cylinder (Duo)
versions, and versions for use with
compressed air airlines. Duo models are

2.2 HARNESS
Contour is available with a flame-
retardant polyamide/ polyester or a
TM
Kevlar
/NomexTM harness (identified by
a -K in the unit part number). Buckles are
of black nylon or stainless steel. Pressstuds are of brass or nickel plated brass.
On Kevlar
TM
versions the pneumatics and
hoses are attached to the harness by
loops closed by press-studs. On EN
versions the loops do not open.
For wearer comfort, a lumbar pad (fitted
as standard), or a full back pad (fitted as
an option) is provided. Both are fabricated
from flame-retardant material and packed
with flame retardant, closed cell foam.
The lumbar pad is held in place by four
press-studs. The full length pad is held by
press studs and the harness straps.
A chest-strap is available as an option.
2.3 CYLINDER BAND
Contour can be configured for use with
one or two (Duo), 200, 207 or 300 bar,
steel or fully wrapped aluminium carbon
fibre composite cylinders (see Table 3).
Cylinders are secured to the light-weight
back-plate by a webbing cylinder band
and a cylinder valve retainer (CVR). A
conversion kit is available for converting
single cylinder apparatus to Duo.
The webbing cylinder band is closed by a
cam lock buckle with a latch that prevents
accidental opening. The band can be
adjusted to accept the range of cylinders
listed in Table 3. The cam-lock buckle
facilitates replacement of similar size
cylinders without cylinder band
adjustment.
Contour Duo cylinder bands can be
easily altered by the wearer (no tools
required) to mount a single cylinder,
centrally on the back-plate.
