4 Description and Intended Use
The Dräger PAS Colt Series of Bandolier Airline/Escape equipment
consists of:
●Bandolier Shoulder Harness with Waist Belt.
●Pressure Reducer with integral Lung Demand Valve (LDV).
●Hip Mounted Cylinder Carrying Holster.
●Airline Manifold Connection – with or without low pressure whistle
warning unit (LPWWU).
●Valved Cylinder Assembly with Contents Indicator.
The equipment is available in either 10 minute, 15 minute or 20 minute
nominal escape duration versions.
4.1 Optional Variants
●Pressure Reducer with ChargAir – Direct Filling Assembly.
●Cylinder Carrying Holster – Drop Down. If applicable, refer to
additional enclosed Instructions for Use.
Important Note: When using equipment fitted with a ChargAir
connection it is necessary to refer to the Use of ChargAir – Direct
Filling instructions supplied with the equipment.
4.2 Accessories
●Thigh strap
This series of equipment utilises a high performance first stage pressure
reducer in association with an integral lung demand valve. The equipment
is compatible with a range of face mask and compressed air cylinders.
When used in approved carrying system, valved cylinder assembly, LDV
and face mask combinations, the equipment provides the wearer with
respiratory protection when working in, or escaping from a contaminated
or oxygen deficient gaseous atmosphere.
When the airline manifold coupling of the equipment is connected to a
low-pressure independent air supply of breathable air quality, (e.g. Dräger
AirPack System or filtered works airline), then the equipment functions as an
airline working set. In this configuration the cylinder valve of the equipment is
in the closed position. On failure or interruption of the independent air supply
the wearer opens the cylinder valve, disconnects the independent air supply
from the airline manifold connection and then proceeds to escape to a safe
area using the available air supplied from the cylinder.
During escape, the effective duration of the equipment is dependant on the
capacity (volume) of the cylinder selected and the breathing rate of the
wearer.
Safety Warning: When the equipment is worn as an airline working
set then the escape duration starts from the time of opening the
cylinder valve and disconnecting the airline supply. The time
required to allow the wearer to escape to a safe area must be within
the capacity (volume) of the cylinder selected taking into account the
breathing rate of the wearer. When selecting the type and duration of
escape equipment it is essential to consider the potential hazards,
and probable escape routes.
Details of the equipment variants, accessories, and any approved
independent air supply source configurations are available from Dräger on
request.

Refer also to the Instructions for Use for the lung demand valve, face mask and other associated equipment.
Additional inspection and testing may be required in the country of use to ensure compliance with national regulations.
Dräger recommendations
1. Clean the equipment if it is dirty. If it the equipment has been exposed to contaminants, disinfect any components that come into direct and prolonged
contact with the skin.
2. These maintenance tasks may only be carried out by Dräger or trained service personnel. Details of the tests are contained in the Technical Manual
which is issued to service personnel that have attended a relevant Dräger maintenance course.
3. For type A check the O-ring on the lung demand valve; and for type ESA check the outer surface of the male part of the push-in connector on the
lung demand valve. As a guide, lubricant should be felt on the fingers but not seen. If relubrication is required, lightly apply Dow Corning®
Molykote®111 (other lubricants are not tested and may damage the equipment).
4. Replace the sintered filter if a drop in reducer performance is observed during a flow check or if it is visibly damaged.
5. Replace the high-pressure connector O-ring if it is found to leak during functional testing or if the O-ring is visibly damaged.
6. Where the breathing apparatus is subjected to a high level of use (in training establishments etc.), reduce the overhaul period for the pressure reducer.
In these circumstances, Dräger recommend that the overhaul frequency should be less than 5,000 applications of use. An application of use is defined
as a single use of the fully assembled breathing apparatus, where the user breathes from the air cylinder. It does not include system pressurization
for pre-operational checks.
