2 Description
2.1 Product overview
This variant of the Dräger PAS® Colt series provides respiratory protection
for working in a contaminated environment using an airline (supplied airline
respirator – SAR), or escaping from a contaminated environment using the
air cylinder (self-contained breathing apparatus – SCBA).
During airline use, the PAS® Colt is connected to a breathing-quality
independent air supply and the cylinder valve is closed. If the independent
air supply falls below the required pressure, the wearer opens the cylinder
valve, disconnects the independent air supply and then escapes to a safe
area breathing air from the cylinder. The time available for the escape is
dependent on the capacity (volume) of the cylinder and the breathing rate
of the wearer.
The features of the equipment are:
● The carrying system is a bandolier shoulder harness and waist belt.
● The lung demand valve (second-stage regulator) has a reset
button (Fig 1, Item 1) that switches off the air flow through the
regulator, and a purge button (Fig 1, Item 2) that can be used to deliver
an additional airflow into the face mask when required by the wearer
during airline use. The holder (Fig 2, Item 1) provides a stowage point
to protect the regulator coupling and O-ring against damage when it is
not fitted in the face mask.
● The first-stage regulator (Fig 2, Item 2) has an anti-vibration strap fitted
that is used to prevent loosening of the connector hand wheel.
● The airline connector (Fig 2, Item 3) is a male coupling that is used to
connect an independent air supply for supplied airline respirator (SAR)
use.
● A low-pressure whistle is fitted on some variants of this product (see
Section 2.1.1).
● The hip-mounted cylinder holster has a drop-down facility that can
assist wearer movement by making the cylinder and holster more
maneuverable (in a confined space for example).
● The remaining pressure in the air cylinder is shown on a contents
indicator on the cylinder.
● A thigh strap is available as an accessory.
2.1.1 Low-pressure whistle (optional)
If the PAS® Colt is fitted with a low-pressure whistle, it operates as follows:
● During airline use, the whistle sounds to warn the wearer that the
independent air supply has fallen below the required pressure.
NOTICE
During an escape (when the wearer is breathing from the air cylinder), the
whistle sounds when the cylinder pressure is very low. This is not an end-
of-service-time indicator (EOSTI).
See the technical data (Section 9) for the whistle operating pressures.
2.2 Intended use
When this product is used with an approved face mask, air cylinder and
independent air supply, it provides the wearer with respiratory protection
for working in, or escaping from, contaminated or oxygen-deficient
conditions. It is intended for use in applications where a high level of
respiratory protection is required, including IDLH (immediately dangerous
to life and health) atmospheres.
The air cylinder, face mask and other accessories used with this product
must be certified Dräger components, assembled in an approved
configuration; otherwise the operation of the device may be impaired.
Contact Dräger for further information.
2.3 Limitations on use
This product is not approved for use in CBRN applications.
2.4 Approvals
The PAS® Colt series of combination escape/airline respiratory protection
equipment conforms to the requirements of NIOSH. This product is
approved for use as a supplied airline respirator (SAR) and as a self-
contained escape respirator, and must only be used in conjunction with
compressed-air cylinders approved by NIOSH.
3 Use
WARNING
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.
The cylinder and airline air quality shall meet the requirements for
breathing air according to CGA G-7.1 Grade D or higher quality.
Before using airline equipment, ensure that the independent air supply
meets the air quality requirements and complies with pressure, flow and
hose length requirements in the technical data (see Section 9), and has
been issued with a permit for use if necessary.
If using a PAS® Colt without an integral low-pressure whistle, Dräger
recommend that a low-pressure warning device is fitted to the
independent air supply.
NOTICE
After storage at temperatures below 32 °F (0 °C) leakage may be observed
when the cylinder valve is initially opened due to ice formation.
► If leakage is observed from the lung demand valve: Press the front
button (Fig 1, Item 3) to allow a rush of air to pass through the lung
demand valve and then quickly press the reset button (Fig 1, Item 1)
to switch off the positive pressure. Resume normal operation.
► In the event that leakage still occurs, remove the breathing apparatus
from service and report the fault to trained service personnel or

Combination escape SCBA/airline SAR respiratory protection equipment Instructions for use
i
ready position until an escape is necessary. Depending on the intended
use, refer to the relevant procedures from the following:
● For combination (escape/airline) use, see Section 3.2.1
● For escape use only, see Section 3.2.2
3.2.1 Combination (escape/airline) use
Putting on the face mask
1. Press the reset button (Fig 1, Item 1) of the lung demand valve to
switch off the positive pressure.
2. Connect the independent air supply to the male coupling (Fig 2,
Item 3). If the independent air supply has a shut-off valve, open the
valve.
WARNING
Correct fit of the face mask can only be achieved if the complete face mask
seal makes contact with skin. Head hair, facial hair (including beard stubble
and sideburns), earrings, other facial piercings and normal spectacles will
interfere with the face mask seal and are not permitted in the sealing area.
Additionally, head hair that could affect the face mask fit (buns, pony-tails,
hairpieces, etc.) is not permitted.
NOTICE
Refer also to the face mask instructions for use.
3. Spread the head harness (Fig 5). Place the chin into the chin cup of
the face mask and pull the harness over the head locating the harness
center plate on back of the head.
4. Referring to Fig 6, tighten both lower (1) and then upper straps (2)
evenly towards back of the head. The wearer’s first inhalation after
achieving a face seal will automatically switch on the air supply into the
face mask.
5. Check that the head has a full range of movement without pulling
against the regulator hose. If any resistance to movement is felt,
readjust the hose routing and then recheck. If resistance is still felt, do
not use the breathing apparatus and contact Dräger.
Function check
1. Isolate the independent air supply (close the valve or disconnect) and
breathe normally to empty the system of air. When empty, the face
mask should hold on to the face to indicate a positive seal.
2. Immediately reapply the independent air supply and breathe normally.
3. Inhale and hold your breath – there should be no audible leak. If a leak
is detected, readjust the head harness and retest.
4. Recommence breathing – exhaled air should flow easily out of the
exhalation valve.
5. Momentarily press the purge button (Fig 1, Item 2) to check for
additional airflow.
When the function check has been satisfactorily completed, breathe
normally and proceed to the working area.
Escape procedure (independent air supply failure)
WARNING
During supplied airline respirator (SAR) use, the PAS® Colt cylinder valve
must remain closed. The escape duration starts from the time of opening
the cylinder valve and disconnecting the airline supply.
Dräger strongly advise that the purge button (Fig 1, Item 2) is not used
during an escape. Using the purge button would use air from the cylinder
and reduce the time available for escape.
NOTICE
If the PAS® Colt is fitted with a low-pressure whistle, during airline use the
whistle sounds to indicate that the independent air supply has fallen below
the required pressure. If the whistle sounds and then stops before the
escape procedure is started, the air supply pressure could have been
restored. The wearer must confirm that the correct pressure (87 to
125 psi) is available, or escape as described below.
If the independent air supply fails, breathe normally and immediately
proceed as follows:
1. Open the cylinder valve (counterclockwise) slowly, but fully, and
continue to breathe normally.
2. Disconnect the independent air supply from the PAS® Colt.
3. Immediately leave the hazardous area by the shortest and safest
escape route.
The wearer must be in a safe area before the air cylinder is empty. When
in a safe area, remove the lung demand valve from the face mask if
necessary and continue to breathe normally.
NOTICE
If the PAS® Colt is fitted with a low-pressure whistle, during an escape the
whistle would sound when the cylinder pressure was in the range 72.5 to
58 psi. This is not an end-of-service-time-indicator (EOSTI).
3.2.2 Escape use only (putting on the face mask and escaping)
WARNING
Correct fit of the face mask can only be achieved if the complete face mask
seal makes contact with skin. Head hair, facial hair (including beard stubble
and sideburns), earrings, other facial piercings and normal spectacles will
interfere with the face mask seal and are not permitted in the sealing area.
Additionally, head hair that could affect the face mask fit (buns, pony-tails,
hairpieces, etc.) is not permitted.
NOTICE
Refer also to the face mask instructions for use.
1. Press the reset button (Fig 1, Item 1) of the lung demand valve to
switch off the positive pressure.
2. Open the cylinder valve (counterclockwise) slowly, but fully, to
pressurize the system.
3. Spread the head harness (Fig 5). Place the chin into the chin cup of
the face mask and pull the harness over the head locating the harness
center plate on back of the head.
4. Referring to Fig 6, tighten both lower (1) and then upper straps (2)
evenly towards back of the head. The wearer’s first inhalation after
achieving a face seal will automatically switch on the air supply into the
face mask.
WARNING
The duration of the cylinder air begins from the time of the first-breath
activation of the lung demand valve.
Dräger strongly advise against using the purge button (Fig 1, Item 2) or
the front button (Fig 1, Item 3) during an escape. Using either button
would use air from the cylinder and reduce the time available for escape.
5. Immediately leave the hazardous area by the shortest and safest
escape route.
The wearer must be in a safe area before the air cylinder is empty. When
in a safe area, remove the lung demand valve from the face mask if
necessary and continue to breathe normally.
3.2.3 Drop-down cylinder holster
To release the drop-down cylinder holster:
a. Hold the cylinder valve with the left hand and, with the right hand,
press and hold the red button to open the locking
mechanism (Fig 7).
b. Lift the cylinder and holster clear of the locking mechanism and
then release the red button (Fig 8).
c. Lower the cylinder until it is supported by the harness
straps (Fig 9). The holster is held by two harness straps, one fixed
and one adjustable.
d. Hold the cylinder valve to move the cylinder and holster as
required.
To reconnect the drop-down cylinder holster, align and press the roller on
the holster into the locking mechanism.
3.3 After use
WARNING
Do not remove the equipment until in safe area, clear of hazard.
CAUTION
Do not drop or throw down equipment as damage could occur.
1. Loosen the face mask straps. As the seal between the face mask and
the face is broken, press the reset button (Fig 1, Item 1) to switch off
the positive pressure. Remove the face mask and fully extend all of the
straps of the head harness.
○ After airline use – isolate and disconnect the independent air
supply from the PAS® Colt. Refit the cap on to the airline
connector.
○ After an escape – close the cylinder valve.
2. Press the purge button (Fig 1, Item 2) to fully vent the system.
3. Remove the lung demand valve from the face mask and stow it in the
holder (Fig 2, Item 1).

5.2.2 Air cylinder charging
WARNING
Air quality for compressed-air cylinders must conform to the minimum
grade requirements for Type 1 gaseous air as defined in CGA (Commodity
Specification for Air) G-7.1 Grade D or higher quality.
If the breathing air moisture content exceeds recommended levels, ice
particles can form, reducing or blocking airflow. Water content of the
breathing air in any container must be checked.
● Refer also to the instructions supplied with the cylinder and the
charging unit for recharging the cylinder.
● Only charge compressed-air cylinders which: conform to national
standards, feature the original manufacturer’s test date and test mark,
have not exceeded the test date indicated on the cylinder by the last
testing station, and are not damaged.
● To prevent ingress of moisture into the cylinder, ensure that the
cylinder valve remains closed until connected to the charging unit.
● Recharge to the rated working pressure of the cylinder. Dräger
recommend a charge rate of 300 psi/minute. Rapid charging will
increase the temperature resulting in an incomplete charge. Recheck
at ambient temperature and top up the charge if required.
● To prevent overcharging of the cylinder, Dräger recommend using a
pressure-limiting device on the charging compressor.
