Maintenance
CAUTION
Danger of material damage!
Mould may form on the chemical protective suit.
► Completely dry the chemical protective suit.
1. Drain any excess liquid from the chemical protective suit
before drying or use a sponge to mop up the excess.
2. Dry all parts thoroughly inside and out. The chemical
protection suit can be blow dried with dry, oil-free
compressed air or dried in a protection suit dryer system:
– Temperature: maximum 40 °C
– Time: at least 120 minutes
Avoid direct heat or long-term exposure to sunlight.
Suitable drying systems for the chemical protective suit
include:
– TopTrock SF01 with GF fan
– Drying systems of an equivalent design
3. Visual inspection of chemical protective suit, full face
mask, protective boots and gloves.
4. Re-fit the air supply unit. Re-fit the cover strap where
necessary.
5. For chemical protective suits with face cuff, apply talc to
the face cuff inside and outside after every cleaning and
disinfection process so that the material does not become
stuck together.
6.4
Maintaining the fastener system
1. Lubricate the fastener system thoroughly after every use
and every cleaning and disinfection process. Use the
grease stick available from Dräger to do this.
2. In particular, lubricate the chain links on the zip fastener
and the area below the chain links on which the zip is
running.
To prevent the fastener system sticking, protruding textile
threads must be removed.
6.5
Checking the seal on the chemical
protective suit
The test is described for the test device Porta Control 3000.
You can carry out the tests with other test devices, but the
indicated values must be observed.
Carry out the test according to ISO 17491-1, method A.2 at
constant room temperature (20 °C±5 °C).
The compressed air used must comply with the requirements
of EN 12021.
The required test accessories are listed in the order list (see
"Order list", page 41).
6.5.1 Preparing the test
1. Seal the connections for protective suits with ventilation
unit.
2. For protective suits with face cuffs:
a. Blow up the sealing pad moderately and close with a
hose clip.
b. Moisten the sealing pad with water and insert through
the open fastener system into the hood on the
protective suit.
32
c. Continue to blow the sealing pad until the face cuff is in
position all-round.
d. Seal the sealing pad with a hose clip.
3. For protective suits with integrated full face mask:
a. Remove the protective cap from the connector.
b. Compress the exhalation valve and inhalation valve
using the test accessories.
4. Close the fastener system.
5. Spread out the protective suit with the rear section
downwards
6. Unfasten the protective cap from the suit valve and
remove the valve disc.
7. Fit the double protective cap onto the suit valve.
8. Connect one connection of the test cap to the test unit via
the blue hose.
9. Ensure that both valves are connected to the black hose
of the test unit.
10. Connect the other connection of the test cap to the
compressed air supply (6 bar) via the black hose.
11. Carry out the test. For further information see: "Carrying
out the test", page 32.
6.5.2 Carrying out the test
CAUTION
Danger of material damage!
If the suit is overfilled, the material will be damaged.
► When filling the chemical protective suit ensure that the
pressure does not exceed the specified values.
1. Open the blow up valve on the black hose and fill the
chemical protective suit until the test unit shows
17.5 mbar. Close the blow up valve.
2. Set a settling time of 10 minutes and start the stopwatch.
During this time, keep the pressure at approx. 17 mbar so
that a pressure and temperature compensation can be
carried out. If required, top up the air.
3. Open the relief valve. Lower the pressure to 16.5 mbar.
Close the relief valve.
4. Set a test time of 6 minutes and start the stopwatch.
5. Read off the pressure on the test unit at the end of the test
time.
If the pressure drop is less than or equal to 3 mbar, the
chemical protective suit is deemed sealed. Then disassemble
the test setup and the suit valves.
If the pressure drop is greater than 3 mbar:
1. Moisten critical points (such as seams, fastener system,
and glove and boot connections) with soapy water.
2. Mark leaking areas.
3. Wash off the soapy water and thoroughly dry the chemical
protective suit.
4. De-aerate and repair the chemical protective suit.
5. Repeat the leak test.
Alternatively, the chemical protective suit can be returned to
Dräger for repair.

Checking the seal on the suit valve
The test is described for the test device Porta Control 3000.
You can carry out the tests with other test devices, but the
indicated values must be observed.
