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.
● Ifleakageisobservedfromthelung demand regulator: Press the purge
button(Fig1,Item2)toallowarushofairtopassthroughthelungdemand
regulatorandthenquicklypresstheresetbutton(Fig1,Item1)toswitchoff
the positive pressure. Resume normal operation.
● Intheeventthatleakagestilloccurs,removethebreathingapparatusfrom
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 affect the operation of the breathing apparatus include impact, abrasion,
cutting, corrosion and discoloration. Report damage to service personnel and do not use
theapparatusuntilfaultsarerectied.
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 handwheel 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 handwheel of
therst-stageregulatorwhileinsertingthecylinder.
1. Align the cylinder with the regulator and tighten the handwheel hand tight (Fig 4).
2. Pull the anti-vibration strap over the top of the cylinder valve (Fig 5).
3.1.3 Functional testing
!
WARNING
If the breathing apparatus fails to meet any of the standards or parameters
described in the functional tests, or if an immediate leak is evident, there is a
system fault. Report the fault to trained service personnel or contact Dräger. Do
notusethebreathingapparatusuntilthefaultconditionisrectied.
Leak test
1. Ensure that the pointer of the cylinder pressure indicator is inside the green area.
2. Presstheresetbutton(Fig1,Item1)ofthelungdemandregulatortoswitchoffthe

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.

3.1.4 Putting on the PAS Colt (ready position)
Refer also to Fig 2 which shows the PAS Colt worn in the ready position.
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. InspectthefacemaskasdenedintherelevantInstructionsforUse.
7. Check that the face mask port and the regulator O-ring are clean and undamaged.
8. Remove the lung demand regulator 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 centre strap of the head harness.
3.2 During use
This variant of the PAS Colt Series can be used for combination (escape/airline) use or
purely for escape use. For combination use the face mask is worn during the task; and
for escape use the PAS Colt is worn in the ready position until an escape is necessary.
Depending on the intended use, refer to the relevant procedures from the following:
● Forcombination(escape/airline)use,seeSection3.2.1
● Forescapeuseonly,seeSection3.2.2
3.2.1 Combination (escape/airline) use
Putting on the face mask
1. Presstheresetbutton(Fig1,Item1)ofthelungdemandregulatortoswitchoffthe

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 t 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,
headhairthatcouldaffectthefacemaskt(buns,pony-tails,hairpieces,etc.)is
not permitted.

3. Detach the neck strap stud from the center strap of the head harness.
4. Spread the head harness (Fig 6). 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.
5. Referring to Fig 7, tighten both lower (1) and then upper straps (2) evenly towards
backofthehead.Ifnecessary,tightenthecenterstrap(3).Thewearer’srstinhalation
after achieving a face seal will automatically switch on the air supply into the face

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
facetoindicateapositiveseal.(ThePASASVwhistlewillmomentarilysoundatthe

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).
The features of the equipment are:

● Therst-stageregulator(Fig2,Item2)hasananti-vibrationstrapttedthatisuseto
prevent loosening of the connector handwheel.
● The Dräger PAS ASV (Fig 2, Item 4) allows the PAS Colt to be used with an
independent air supply such as a factory airline or other breathing air supply (e.g.
Dräger PAS AirPack). See Section 2.1.1 for a detailed description.
● Theairlineconnector(Fig2,Item 3) is a male coupling that is used to connectan
independent air supply for supplied airline respirator (SAR) use.
● The hip-mounted cylinder holster has a dropdown facility that can assist wearer
movement by making the cylinder and holster more manoeuvrable (in a conned
space for example).

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
airqualityrequirements,andcomplieswiththepressure,owandhoselength
requirements in the technical data (see Section 9), and has been issued with a
permit for use if necessary.
