Dräger BG ProAir
Use
4.1.4 Reuse
Under the following prerequisites, the closed-circuit breathing
apparatus can be used multiple times by the same user within
24 hours:
– The officer-in-charge decides whether the remaining
oxygen supply is adequate before each further use.
– The cylinder valve is fully closed after every use. The
connecting piece is sealed with the protective cap.
– The compressed oxygen cylinder and CO
2
absorber are
not replaced.
– The ambient temperature is no less than +10 °C when the
closed-circuit breathing apparatus is not being used.
– The closed-circuit breathing apparatus is placed in a
upright position (not laid down).
4.2 Prior to first use
1. Perform a visual inspection. The closed-circuit breathing
apparatus must be intact and complete.
2. Insert batteries into the closed-circuit breathing apparatus
(see "Replacing the batteries", page 26).
3. Remove the thin, flexible protective foil from the LC
display and the LED panel on the Connect ECU. The LC
display and LED panel also have a clear, protective cover
that must not be removed.
4. Carry out a leak and functional test (see "Testing the
closed-circuit breathing apparatus", page 22).
4.3 Preparations for use
4.3.1 Freezing the ice packs (for apparatuses
with ice cooler)
1. Stack the ice packs flat on top of each other.
2. Freeze the ice packs at -16 °C for 24 hours.
If significant deformations are apparent on the ice pack,
allow the ice pack to thaw and then freeze again. Dräger
recommends using the respective freezing aid to prevent
the ice packs from deforming.
Make sure that no ice is deposited on the ice packs. If
necessary, place ice packs in a bag, seal the bag and
freeze the ice packs whilst they remain in the bag.
Dräger recommends storing completely frozen ice packs
in a sealed bag in the freezer.
4.3.2 Inserting ice packs (for apparatuses with
ice cooler)
1. Open the closed-circuit breathing apparatus (see
"Opening the closed-circuit breathing apparatus",
page 16).
2. Open the ice cooler.
3. Insert the ice packs.
Only use ice packs that are not deformed. Do not press
the ice packs into the ice cooler to ensure they do not
become damaged and leak.
4. Close the ice cooler.
5. Close the closed-circuit breathing apparatus (see "Closing
the closed-circuit breathing apparatus", page 22).
4.3.3 Donning the closed-circuit breathing
apparatus
1. Open the quick-release buckles of the waist belt and chest
strap.
2. Unfasten both shoulder straps. To do so, push the
adjusting clamp upwards with your thumb and pull on the
adjusting clamp.
3. Hang the breathing hoses over the lid.
4. Reach your arms through the shoulder straps and lift up
the closed-circuit breathing apparatus.
5. Position the closed-circuit breathing apparatus.
6. Make sure that the shoulder straps are tensioned so that
the padding on the waist belt rests on your hips.
7. Close the waist belt and adjust the width. To do so, pull the
ends of the belt tight until the closed-circuit breathing
apparatus rests firmly on your hips.
8. Place the breathing hose in front of your body.
9. Evenly pull the shoulder straps tight and adjust them so
that the apparatus is comfortable to wear.
10. If necessary, close the chest strap and pull tight.
11. Don the full face mask.
