4.7.1 Preliminary decontamination of the suit
WARNING
!
Never touch contaminated parts unless wearing protective clothing.
Avoid contaminating the clean interior of the protective suit.
1.
Leave the contaminated area and have someone else perform preliminary
decontamination. The assistant must wear protective clothing and, where
necessary,

decontamination of chemical or biological materials, Dräger recommends
using plenty of water to which a detergent has been added. This will be
sufficient to wash away most chemicals (acids, alkalis, organic and
inorganic chemicals).
2.
Dispose of the contaminated chemical protective suit after removal and the
contaminated waste water in accordance with the applicable waste disposal
regulations.

of the zip mechanism. Do not use force.
2.
Remove the left arm from the sleeve.
3.
Crouch down and get the head clear of the hood.
4.
Remove the right arm from the sleeve.
5.
Fold the chemical protective suit away from the wearer in such a way that,
if possible, no chemicals or cleaning agents enter the interior of the suit.
6.
Climb out of the socks and trouser legs.
7.
Set down the protective helmet, SCBA and cotton gloves in the non-
contaminated area.

Perform a visual inspection of the chemical
protective suit
Check that the chemical protective suit is sealed
Check that the suit valves are sealed

With chemical protective suits that are stored in the relevant carrying bag,
the interval is extended to two years.
5.1
Performing a visual inspection of the chemical protective suit
The following checks are mandatory. The chemical protective suit must be
disposed of in case of defects.
Check the outer of the chemical protective suit for holes, cuts or abrasion.
Check whether the seam tape is lifting up or peeling off.
Check that the seal of the visor is intact and that the visor is clean.
Check that the gloves are not damaged. For chemical protective suits with
glove combinations, check the inner and outer glove.

Check that the closure system and cover are not damaged. Grease the
closure system as necessary with the grease stick.
Check that the suit valves are unobstructed and undamaged.
Check the suit material for signs of wear (white lines) or ozone damage
(white chalky dots) and for the coating coming away from the fabric.
5.2
Checking that the chemical protective suit is sealed
The test is described for the Porta Control 3000 test unit. You can carry out the
tests with other test units, but the indicated values must be observed.
Carry out the test in accordance with ISO 17491-1 Method A.2 at constant room
temperature (20°C ±5°C).
preliminary
The compressed air used must comply with the requirements of EN 12021.
The required test accessories are listed in the order list (see section 9 on
page 8).
5.2.1 Preparing for the test
1.
For protective suits with a ventilation unit, seal the connections.
2.
Close the closure system.
3.
Spread out the chemical protective suit on its front on a clean and flat
surface.
4.
Protect the visor with a soft underlay in order to avoid scratches.
5.
Unfasten the protective caps from both suit valves and remove the valve
discs.
6.
Fasten a test cap onto one of the suit valves and connect to the test unit via
the blue hose.
7.
Fasten another test cap on the other suit valve.
8.
Make sure that both valves on the black hose of the test unit are closed.
9.
Connect the test cap via the black hose to the compressed air supply
(6 bar).
10. Carry out the test (see section 5.2.2 on page 6).
5.2.2 Carrying out the test
CAUTION
!
If the suit is overfilled, the material will be damaged.
When you fill up the chemical protective suit, make sure that the
pressure does not rise too far above the specified values.
1.
Open the exhaust valve on the black hose and fill the chemical protective
suit until the test unit shows 17.5 mbar (179 mm WC). Close the exhaust
valve.
2.
Set a settling time of 10 minutes and start the stopwatch. During this time,
keep the pressure at approx. 17 mbar (173 mm WC) to enable a pressure
and temperature compensation. If required, top up the air.
3.
Open the vent valve. Reduce the pressure to 16.5 mbar (168 mm WC).
Close the vent valve.
4.
Set a test time of 6 minutes and start the stopwatch.
5.
At the end of the test time, read off the pressure on the test unit.
If the pressure drop is less than or equal to 3 mbar (30 mm WC), the chemical
protective suit is deemed sealed. Now disassemble the test setup and check the
suit valve.
If the pressure drop is greater than 3 mbar (30 mm WC), check to see if there is
an error in the test setup. If it is certain that there are no errors in the test setup,
the chemical protective suit must be disposed of.
5.3
Checking that the suit valves are sealed
The test is described for the Porta Control 3000 test unit. You can carry out the
tests with other test units, but the indicated values must be observed.
Carry out the test in accordance with EN 943-1, 6.5.1, but with a 10-mbar

3.
Place the pumping ball on the vent valve into the black hose such that the
arrow on the pumping ball points to the vent valve.
4.
Moisten the valve disc with plain water and attach.
5.
Fasten the test cap to the valve from the outside and connect to the test unit
via the connecting hose.
6.
Open the vent valve, use the pumping ball to generate an overpressure of
+10 mbar (102 mm WC). Close the vent valve.
7.
Set a test time of 1 minute and start the stopwatch.
8.
At the end of the test time, read off the pressure on the test unit.
If the pressure change is less than 1 mbar (10 mm WC), the suit valve is OK. In
this case:
1.
Check the next suit valve.
