2 Description
2.1 Product overview
The Dräger PAS Colt PPH (positive-pressure hood) provides respiratory
protection for use in a contaminated or oxygen-deficient environment to
escape to a safe breathing environment or to a designated holding area.
In the designated holding area the PAS Colt PPH air cylinder can be
recharged, and then kept fully charged, by a charging air source
(ChargAir). This allows the wearer to breathe normally in the holding area,
and then to escape a safe breathing environment when a full evacuation is
possible.
The main features of the product are:
●The carrying harness is a bandolier shoulder harness and waist belt.
●The air cylinder is a carbon-composite cylinder fitted in a hip-mounted
cylinder holster. The cylinder pressure is shown on the gauge (Fig 1,
Item 4), and when the cylinder is full it provides a nominal duration of
15 minutes.
●The cylinder valve has an automatic activation device that is operated
by removing a two-pronged locking clip (Fig 1, Item 1). The clip is
connected by a strap to a sprung-gate clip (Fig 1, Item 6) that
automatically pulls the locking clip as the escape hood is removed from
its storage pouch.
●The pressure reducer (Fig 1, Item 2) reduces the cylinder pressure to
a medium pressure, which is the pressure required at the lung demand
valve (Fig 1, Item 5).
●The ChargAir connector (Fig 1, Item 7) is a male coupling that is used
with a charging air source to rapidly refill the air cylinder while the
wearer is breathing from the equipment. The ChargAir connector
contains a pressure-relief valve (Fig 1, Item 3) that prevents over
charging and possible cylinder damage by opening to relieve pressure
at a set level above 200 bar. If the pressure-relief valve activates, the
breathing apparatus must be returned to Dräger for inspection and
repair for safety reasons.
●The ChargAir outputs in the holding area must be female Aeroquip
couplings (FD17-1003-04-04).
●The escape hood (Fig 2) has a rubber ring that seals around the neck,
and an internal nose cup that fits over the nose and mouth to supply
air to the wearer.
●The lung demand valve regulates the breathing air supply to the
wearer during use. The valve is switched on by the inhalation of the
wearer (first-breath activation), and can be switched off by pressing a
reset button (Fig 2, Item 1) when required.
2.2 Intended use
When this product is used with an approved air cylinder it provides the
wearer with respiratory protection for: escaping from contaminated or
oxygen-deficient conditions; or for remaining in a holding area with a
compatible charging air source.
The air cylinder used with this product must be a certified Dräger cylinder;
otherwise the operation of the product may be impaired. Contact Dräger for
further information.
Operating temperature range: -15 °C to 60 °C.
2.3 Approvals
The European standards, guidelines, and directives according to which
this product is approved are specified in the declaration of conformity (see
declaration of conformity or www.draeger.com/product-certificates).

3 Use
WARNING
The time required to allow the wearer to escape to a safe area
must be within the capacity of the equipment. When selecting the
type and duration of escape equipment it is essential to consider
potential hazards, storage location and escape route.
3.1 Preparation for use
WARNING
On receipt of the PAS Colt PPH from Dräger, the product is not
configured for immediate operational use. The cylinder automatic
activation device is not connected, and the air cylinder may be
discharged. Carry out the following procedure to prepare the product
for use.
Immediately following removal of the equipment from its packaging:
1. If the air cylinder is supplied discharged, see Section 4.2.5 for cylinder
charging instructions.
2. Fit the air cylinder and connect the automatic activation device (see
Section 4.2.2).
3.2 Putting on the carrying harness
Refer also to Fig 1.
1. Check that the pointer of the cylinder pressure gauge is inside the green
area, and the cylinder automatic activation device is properly
connected (Fig 1, Items 1 and 6).
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. Hold 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.
3.3 Putting on the hood and escape procedure
NOTICE
Remove protective head gear before putting on the hood.
1. Remove the hood from the pouch. This action removes the locking clip
(Fig 1, Item 1), automatically activating the cylinder valve.
2. Place both hands inside the neck seal and stretch the hood over the
head.
○Wearers with spectacles – take care when stretching the neck seal
over the spectacles.
○Wearers with long hair – tuck the hair inside the hood.
3. Position the nose cup over the nose and mouth, and inhale to activate the
breathing air supply. The duration of the cylinder air begins from the time of
the first-breath activation of the lung demand valve.
NOTICE
The actual breathing time available from the cylinder depends on the
wearer’s air-use rate. Higher breathing rates associated with
increased physical effort would reduce the available escape time.
The wearer must be able to reach the required area before the air
cylinder is empty.
4. Breathe normally and immediately proceed to one of the following
areas:
○A safe breathing environment (see Section 3.3.1).
○A designated holding area with a ChargAir breathing air supply
(see Section 3.3.2).
3.3.1 Safe breathing environment
WARNING
Do not remove the hood until in a safe breathing environment.
CAUTION
Do not drop or throw down equipment as damage could occur.
Once in a safe breathing environment:
1. Remove the hood and continue to breathe normally.
2. Press the reset button (Fig 2, Item 1) to switch off the air flow through
the lung demand valve.
3. Carefully roll the escape hood to ensure that the visor is not creased.
Insert the hood into the pouch with the visor in the lower portion of the
pouch as shown in Fig 1.
3.3.2 Designated holding area (ChargAir use)
WARNING
The ChargAir source shall meet the requirements for breathing air
according to EN 12021.
If the ChargAir system is used in a potentially contaminated
environment, ensure that all couplings are free of contaminants
before connecting the couplings.
CAUTION
The ChargAir source pressure must not exceed 200 bar. Using a
ChargAir source of higher pressure could activate the ChargAir
pressure-relief valve and damage the valve seat. If the ChargAir
pressure-relief valve activates, the breathing apparatus must be
returned to the nearest Dräger branch or agent for inspection and
repair at the first opportunity.
1. Ensure that the charging source outlet connector is compatible with the
ChargAir connector on the PAS Colt PPH (Fig 1, Item 7).
2. Remove the protection caps from the ChargAir connectors.
3. Ensure that the hoses are not bent or kinked and push the ChargAir
connectors together until a click is heard and the ring (Fig 3, Item 1) is
visible behind the sleeve on the female coupling.
○Filling the cylinder begins immediately.
○The cylinder is full when the pointer of the cylinder pressure gauge
is inside the green area. This can be within 60 seconds, although
the filling time and final pressure are dependent on the pressure
and volume of air in the cylinder and the charging air source.
○Due to rapid compression of cylinder air, a small temperature
increase occurs during refilling. The system will top-up the cylinder
as it cools if it remains connected to the charging air source.
4. Keep the ChargAir system connected and breathe normally until a full
evacuation is possible.
5. When required, disconnect the quick coupling by pulling the sleeve of
the female coupling away from the male coupling (see the arrow in
Fig 3). As the coupling separates, a hiss or pop may be heard as the
shut-off valves in the couplings close. The duration of the cylinder air
begins from the time of disconnecting from the ChargAir connector.
6. Immediately proceed to a safe breathing environment (see Section 3.3.1).
3.4 After use
After any use, the product must be checked and then returned to the ready-
for-use condition. The after use maintenance tasks (see Section 4.1.2)
must be carried out by Dräger or trained service personnel to prepare the
product for use.
