Description
2.1
Product overview
The Dräger PAS
®
Lite Series is a self contained breathing apparatus
(SCBA) that uses an open-circuit breathing system. The series is
compatible with a wide range of compressed-air cylinders, face masks and
lung demand valves (e.g. FPS 7000 and Panorama Nova face masks, PSS
Series lung demand valves, and steel or composite cylinders).
2.2
Feature description
The carrying system uses a lightweight polymer-composite space frame
(Fig 1, Item 3). The shoulder straps and waist belt are fully adjustable and
use webbing harness straps with rubberized shoulder straps and a plastic
waist belt buckle.
The apparatus uses the Dräger high-performance pressure reducer (8)
that reduces cylinder pressure and supplies breathing air to the lung
demand valve (1) through a medium-pressure hose (7). Medium-pressure
air is supplied either directly or through a coupling (9) that allows removal
and fitting of the lung demand valve when required. A gauge hose (5)
supplies high-pressure air from the cylinder to the gauge (4). The reducer
also incorporates a whistle (6) that sounds to warn the wearer that there is
low cylinder pressure.
The air hoses and the pressure reducer are integrated into the space frame
to prevent snagging and enhance component protection. The hose clips
(2) hold the air hoses in position on the shoulder straps.
Air cylinders, lung demand valves and face masks
The Dräger PAS Lite Series is compatible with a single steel or composite
material cylinder of 4 to 9 litre capacity, and 200 or 300 bar pressure. Full
descriptions and user instructions are contained in separate instructions
supplied with the cylinder, mask or lung demand valve.
2.3
Intended use
The PAS Lite Series breathing apparatus, when fitted with a cylinder, lung
demand valve and face mask, is intended for use by emergency services
and in industrial applications where a high level of respiratory protection is
required. The assembled breathing apparatus provides the wearer with
respiratory protection for working in contaminated or oxygen-deficient
conditions, and is suitable for fire fighting.
The cylinder, face mask and other accessories used with this product must
be certified Dräger components, assembled in an approved configuration.
Contact Dräger for further information.

Use
WARNING
Only trained and competent personnel may prepare and use
breathing apparatus. Ensure that any accessories, ancillary
equipment and other protective clothing items do not interfere with
the apparatus and do not create a safety hazard.
The effective working duration of the apparatus is dependent on
the initial air supply available and the breathing rate of the wearer.
Fill air cylinders to their full rated pressure prior to use, and do not
commence any operation using a cylinder that is less than 90 per
cent full (or greater when national regulations dictate).
CAUTION
Do not apply excessive force or use tools to open or close a
cylinder valve, and do not drop or throw down the breathing
apparatus.
3.1
Preparation for use
NOTICE
The pressure gauge may be fitted with a thin flexible protective
covering. Remove this covering before first use.
1. Carry out a visual inspection of the breathing apparatus (see
Section 3.5.1).
2. Fit the air cylinder (see Section 3.5.2).
3. For breathing apparatus with a medium-pressure coupling for the lung
demand valve, disconnect and then reconnect the male coupling. To
connect, press the male coupling into the female coupling until an
audible click is heard. If there is any difficulty disconnecting or
connecting, see the troubleshooting information in Section 4.
4. Press the reset button (Fig 1, Item 11) when using a positive-pressure
lung demand valve (see the Instructions for Use supplied with the lung
demand valve).
5. Carry out a full functional test of the apparatus (see Section 3.5.3).
6. Connect the lung demand valve to the face mask and check the
security of attachment by gently attempting to pull the coupling apart.
3.2
Putting on the breathing apparatus
1. Fully loosen the shoulder straps and waist belt and put on the
breathing apparatus.
2. Check that the shoulder straps are not twisted and take the weight of
the system on the shoulders by pulling the shoulder straps. Do not fully
tighten at this stage.
3. Close the waist belt buckle and pull the ends of the waist belt until it fits
securely and comfortably on the waist (Fig 2). Tuck the belt ends
behind the waist belt.
4. Pull the shoulder straps until the breathing apparatus is secure and
comfortable. Do not over tighten. Tuck the belt ends behind the waist
belt.

5. Fully loosen the head straps of the face mask and place the neck strap
over the back of the neck.
6. Press the reset button when using a positive-pressure lung demand
valve.
7. Open the cylinder valve slowly, but fully, to pressurize the system.
8. Put on the face mask and check for tight fit (see the Instructions for Use
supplied with the mask).
3.3
During use
WARNING
Fully open the cylinder valve and ensure that it remains open
during use.
Users should be in a safe area before the whistle warning
commences. Evacuate to a safe area immediately if the warning
commences during an operation.
Using the supplementary air supply (Fig 1, Item 10) will use air
from the cylinder and rapidly reduce the working duration of the
apparatus.
●
Regularly check the remaining cylinder pressure on the gauge.
●
If supplementary air is required, briefly press the rubber cover (10) at
the front of the lung demand valve to deliver extra air into the face
mask.
