2 Description
2.1 Product overview
The Dräger PAS Colt PPM (positive-pressure mask) is an emergency
escape breathing apparatus that 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 PPM air cylinder is recharged,
and then kept fully charged, by a charging air source (ChargAir
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 1), and when the cylinder is full it provides a nominal duration of
15 minutes.
● The pressure reducer (Fig 1, Item 2) reduces the cylinder pressure to
a medium pressure (the pressure required at the lung demand valve
(Fig 1, Item 4) on the mask).
● The ChargAir connector (Fig 1, Item 5) 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 cylinder valve has an automatic activation device that is operated by
removing a two-pronged locking clip (Fig 2, Item 1). The clip is connected
by a strap to a sprung-gate clip (Fig 2, Item 2) that in turn is connected to
a pull ring (Fig 2, Item 3) on the mask. This arrangement automatically
pulls the locking clip as the mask is removed from its protective bag.
● The face mask (Fig 3) has an elasticated five-point head harness, and an
internal nose cup that fits over the nose and mouth to supply air to the
wearer. The mask is normally stored inside a bag on the cylinder holster,
and has a pull handle (Fig 3, Item 1) that is used to pull the mask out of
the bag for use. Pulling the mask out activates the cylinder valve
automatic activation device.
● 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 3, Item 2) 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 Limitation on use
The product weight exceeds 5 kg. This is considered to be unsuitable to be
carried by the wearer for in excess of 8 hours.
2.4 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).
2.5 Explanation of markings and symbols
is the MED mark of conformity.

Instructions for Use

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 PPM 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 4.2.7 for cylinder
charging instructions.
2. Fit the air cylinder and connect the automatic activation device (see
Section 4.2.5).
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 2, Items 1 and 2).
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. Pass 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 face mask and escape procedure
WARNING
!
Correct fit of the face mask can only be achieved if the complete 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
i i
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.
1. Grip the pull handle (Fig 4, A) and pull firmly upward to pull the mask
out of the bag (Fig 4, B).
2. Continue to pull the mask upward to remove the locking clip (Fig 4, C)
and activate the cylinder valve.
3. Using one hand, hold the mask on to the face and, with the other hand,
pull the elasticated head harness firmly over the back of the head,
locating the harness centrally on the head (Fig 5).
4. Tighten both lower straps evenly towards the back of the head (Fig 6).
5. On achieving a face seal, 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.
6. Breathe normally and immediately proceed to one of the following
areas by the shortest and safest escape route:
○ 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 equipment 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 mask and continue to breathe normally.
2. Press the reset button (Fig 3, Item 2) to switch off the air flow through
the lung demand valve.
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 PPM (Fig 1, Item 5).
2. Remove the protection caps from the ChargAir connectors.
3. Ensure that the charging hose is not bent or kinked and push the
ChargAir connectors together until a click is heard and the ring (Fig 7,
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
