2 Description
2.1 Product overview
The Dräger saver PP (positive-pressure) is an emergency escape
breathing apparatus that provides respiratory protection to escape from a
contaminated or oxygen-deficient environment to a safe breathing
environment.
The main features of the product are:
● The respiratory protection equipment is contained in a carrying bag that
has a soft or hard case. If the bag is black it indicates that the bag material
has anti-static properties. The bag has a neck strap to carry the product.
●The air cylinder is fitted inside the carrying bag but has a pressure
gauge (Fig 1, Item 4) that is visible outside the bag. When the cylinder is
full it provides a nominal duration of 10 or 15 minutes (see Section 2.1.1).
●The cylinder valve has an automatic activation device that is operated
by removing a two-pronged locking clip (Fig 1, Item 3). The locking clip
is connected by a strap to a sprung-gate clip (Fig 1, Item 2) that is in
turn connected to a D-ring (Fig 1, Item 1) on the inside of the lid. This
arrangement automatically removes the locking clip as the carrying
bag is opened.
●The pressure reducer (Fig 1, Item 5) reduces the cylinder pressure to
a medium pressure (the pressure required at the lung demand valve).
●The face mask (Fig 2) 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 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.
●There is an anti-tamper tag (or tags) (Fig 3) fitted on the lid of the carrying
bag to allow an inspector to quickly identify that the bag has not been
opened. The soft-case bag has a single anti-tamper tag (Fig 3, A), and
the hard-case bag has two anti-tamper tags (Fig 3, B).
2.1.1 Air cylinders
The saver PP10 version has a 2 litre aluminium cylinder – nominal
duration of 10 minutes.
The saver PP15 version has a 3 litre steel or carbon-composite cylinder
– nominal duration of 15 minutes.
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.
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 saver PP15 version (with 3 litre steel cylinder) exceeds 5 kg. This is
considered to be unsuitable (as defined in EN 402) to be carried by the
wearer for more than 8 hours.
Use in potentially explosive atmospheres
Do not charge the cylinder in a potentially explosive atmosphere.
saver PP Series combinations that are supplied in a black soft-case bag
or hard-case bag have anti-static properties and are type tested as suitable
for use in potentially explosive atmospheres. The combinations are
suitable for use in hazardous areas up to and including zone 0 and zone20.
The combinations can be used in atmospheres containing gases of the gas
explosion group IIC.

WARNING
The time required to allow the wearer to escape to a safe area
must be within capacity of the equipment. When selecting the type
and duration of escape equipment it is essential to consider
potential hazards, storage location and escape routes.
3.1 Preparation for use
WARNING
On receipt of the saver PP 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:
●If the air cylinder is supplied discharged, see Section 4.2.5 for cylinder
charging instructions.
●If the air cylinder is supplied fully charged, carry out the following to
connect the cylinder automatic activation device:
a. Grip the loop on the lid of the carrying bag and pull up to open the
bag.
b. Press the reset button (Fig 2, Item 1) to ensure that the lung
demand valve is switched off.
c. Check that the pressure reducer is secure in the valve port.
d. Seal the lid along the hook-and-loop fastening strip leaving
sufficient opening to insert a hand and, taking care not to detach
the locking clip from the cylinder valve, connect the sprung-gate
clip (Fig 1, Item 2) to the D-ring (Fig 1, Item 1).
e. Fit the anti-tamper tag(s) and close the lid (Fig 3).
3.2 Putting on the carrying bag (ready position)
1. Check that the pointer of the cylinder pressure gauge is inside the
green area, and the anti-tamper device on the lid of the carrying bag is
intact (Fig 3).
2. Place the neck strap over the head (Fig 4, A) and adjust the strap until
the equipment sits in the centre of the chest.
3. If fitted with a waist belt (optional accessory), loop the waist belt around
the waist and then fasten the buckle. Pull the free end of the belt until
the equipment is secure and comfortable.
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
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 loop on the lid of the carrying bag and pull firmly upward to
break the anti-tamper tag(s) and open the lid of the bag (Fig 4, B). This
action removes the locking clip, automatically activating the cylinder
valve.
2. Remove the mask from the carrying bag (Fig 4,C).
3. Using one hand hold the mask on to the face and, with the other hand,
pull the elasticated head harness over the back of the head, locating
the harness centrally on the head (Fig 5).
4. Tighten both lower straps evenly towards 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 leave the hazardous area by the
shortest and safest escape route.
WARNING
Do not remove the equipment until in a safe area and clear of the
hazard.
CAUTION
Do not drop or throw down equipment as damage could occur.
7. Once in a safe breathing environment, remove the face mask.
8. Press the reset button (Fig 2, Item 1) to switch off the air flow through
the lung demand valve.
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 trained service personnel or Dräger to prepare the
product for use.
4 Preparing and maintaining the saver PP
The tasks in this section must be carried out to prepare and maintain the
saver PP in a ready-for-use condition.
4.1 Maintenance periods
4.1.1 Daily checks
It is essential that escape apparatus is ready for use at all times, and
Dräger therefore recommend a daily check. If the customer’s on-site risk
assessment concludes that less regular checks are acceptable, this can be
extended to a maximum of one month. It is the customer’s responsibility to
ensure that the equipment is ready for use at all times.
●Check that the pointer of the cylinder pressure gauge is inside the
green area. Charge the cylinder if it is in the red area (see Section
