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.

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.
Instructions for use
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
contact Dräger.
3.1

Preparation for use

3.1.1

Visual inspection

Carry out a visual inspection, checking the full breathing apparatus
including all component parts and accessories. Check that the equipment
is clean and undamaged, paying particular attention to pneumatic
components, hoses and connectors. Typical signs of damage that may
3 affect the operation of the breathing apparatus include impact, abrasion,
cutting, corrosion and discoloration. Report damage to service personnel
and do not use the apparatus until faults are rectified.
3628/3627
3.1.2

Fitting the cylinder

1. Ensure that the cylinder is fully charged, with the pointer of the cylinder
pressure indicator inside the green area.
2. Check that the threads of the valve port and the regulator hand wheel
are undamaged, and the O-ring is in position and undamaged.
3. Fully insert the cylinder into the carrying holster.
CAUTION
To prevent damage, ensure that the cylinder remains clear of the hand
3631
wheel of the first-stage regulator while inserting the cylinder.
4. Align the cylinder with the regulator and tighten the hand wheel hand
2
tight (Fig 3).
5. Pull the anti-vibration strap over the top of the cylinder valve (Fig 4).
3.1.3

Functional testing

1
WARNING
If breathing apparatus fails to meet any of the standards or parameters
described in the functional tests, or if an immediate leak is evident, there
3626
is a system fault. Report the fault to trained service personnel or contact
Dräger. Do not use the breathing apparatus until the fault condition is
rectified.
Leak test
1. Ensure that the pointer of the cylinder pressure indicator is inside the
green area.
2. Press the reset button (Fig 1 Item 1) of the lung demand valve to
switch off the positive pressure.
3. Open the cylinder valve slowly, but fully, to pressurize the system and
3633 then close the valve. There should be no audible leak. If there is any
leak, investigate and repair the leak before use. If necessary, use a
soapy solution to locate the leak.
4. Press the purge button (Fig 1, Item 2) to vent the system.
Airline flow test (only required for airline use)
1. Press the reset button (Fig 1, Item 1) of the lung demand valve, and
then check that the cylinder valve is closed.
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
Do not direct the airflow on to the face, eyes or skin.
3. Press the purge button (Fig 1, Item 2) for 3 to 5 seconds. An
unobstructed airflow should flow from the outlet of the lung demand
valve.
4. Isolate and disconnect the independent air supply.
5. Press the purge button (Fig 1, Item 2) to vent the system and then
press the reset button (Fig 1, Item 1) to switch off the positive
pressure.

3.1.4 Putting on the PAS Colt (ready position)
Refer also to Fig 2 which shows the PAS
1. Ensure that the pointer of the cylinder pressure indicator is inside the
green area.
2. Open the waist belt buckle and fully extend the waist and shoulder
strap.
3. Place the left arm through the shoulder harness, taking the harness
over the head and on to the right shoulder, positioning the strap
diagonally across the body with the cylinder positioned against the left
hip.
4. Loop the waist belt around the waist and fasten the buckle – do not
tighten.
5. Grip the cylinder valve with the left hand and lift until the waist belt is in
line with the waist. Then tighten the waist belt strap until the equipment
is secure and comfortable on the waist. Pull down to adjust the
shoulder strap.
6. Inspect the face mask as defined in the relevant instructions for use.
7. Check that the face mask port and the regulator O-ring are clean and
undamaged.
8. Remove the lung demand valve from the holder and press it into the
port of the face mask until it latches in position. Check the attachment
by gently attempting to pull the coupling apart.
9. Put the neck strap of the face mask over the head, and then insert the
neck strap stud into the hole in the cent-re strap of the head harness.
