Maintaining The Fastener System; Check The Seal On The Chemical Protective Suit; Check The Seal On The Suit Valve - Dräger WorkMaster Industry Instructions For Use Manual

Maintenance
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: 40 °C at the most
– time: at least 120 minutes
Avoid direct heat or long-term exposure to sunlight.
NOTICE
i i
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. Refit all parts dismantled prior to cleaning.
5. Check if the foam rubber pieces on the metal fasteners of
the protective boots are still attached.
6. Lubricate the fastener system.
6.4

Maintaining the fastener system

Lubricate the fastener system thoroughly after every use

and every cleaning and disinfection process. Use the
grease stick available from Dräger to do this.
In particular, lubricate the chain links on the zip fastener

and the area below the chain links on which the zip is
running.
NOTICE

To prevent the fastener system sticking, protruding
textile threads must be removed.
6.5 Check 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
Chapter 11 on Page 27).
6.5.1 Preparation of test
1. Seal the connections for protective suits with vent valve.
2. For protective suits with integrated full face mask:
a. Remove the protective cap from the connector.
b. Seal the exhalation valve and inhalation valve using the
test accessories.
3. Close the fastener system.
4. Spread out the protective suit with the rear section
downwards.
5. Unfasten the protective cap from the suit valve and remove
the valve disc.
6. Fit the double protective cap onto the suit valve.
7. Connect one connection of the test cap to the test unit via
the blue hose.
8. Ensure that both valves are connected to the black hose of
the test unit.

9. Connect the other connection of the test cap to the
compressed air supply (6 bar) via the black hose.
10. Carry out the test (see Chap. 6.5.2 on Page 22).
6.5.2 Performing the test
CAUTION
!
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 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 considered sealed. Disassemble the
test setup and test the suit valve.
If the pressure drop is greater than 3 mbar:
1. Wet critical spots (e. g. seams, fastener system, glove and
boot connectors) with soap suds.
2. Mark leaking areas.
3. Rinse off the soap suds and dry the chemical protection
suit suit thoroughly.
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.
6.6

Check 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.
Carry out the test according to EN 943-1, 6.5.1, however with
10 mbar overpressure, 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
Chapter 11 on Page 27).
1. Remove the blow up valve with plug-in coupling from the
hose.
2. Connect the hose end to the test unit.
3. Insert the pumping ball on the relief valve into the black
hose in a way that the arrow on the pumping ball points
toward the relief valve.
4. Moisten the valve disc with clear water and fit.
5. Fit the test cap from the outside on the valve and connect
it to the test unit via the connection hose.
6. Open the relief valve and create an overpressure of
+10 mbar with the pumping ball. Close the relief valve.
7. Set a test time of 1 minute and start the stopwatch.
8. Read off the pressure on the test unit at the end of the test
time.
