Leave the contaminated area immediately in a case of emergency. Do not
open closure system until a non-contaminated area has been reached (see
Section 4.6 on Page 13).
Observe the permitted temperature during usage (see Section 8 on
Page 14).

After use
4.6.1 Roughly decontaminating the chemical protective suit
WARNING
!
Never touch contaminated parts without protective clothing.
Avoid contaminating the clean interior of the suit.
1.
Leave the contaminated area and carry out rough decontamination with
the aid of a helper. The helper must also wear protective clothing and
respiratory equipment. For rough decontamination of chemical or biological
contamination, Dräger recommends that you use a lot of water with the
addition of a cleaning agent. This is the best way of washing off most
chemicals (acids, alkalines, organics and inorganics).
2.
Once the suit has been doffed, dispose of the contaminated chemical
protective suit and contaminated waste water in accordance with the
applicable waste disposal regulations.
4.6.2 Doffing the Chemical Protective Suit
NOTICE
i
i
Get a second person to assist you with doffing the suit.
1.
Remove protective boots.
2.
Remove head protection.
3.
Undo straps on full face mask: Place index fingers behind the lugs of the
neck straps and push buckles forward with the thumbs.
4.
Remove full face mask and respiratory equipment.
5.
Open covering flap.
6.
Get a second person to open the closure system. Always pull zipper tab in
direction of zipper mechanism. Do not use force.
7.
Crouch down and remove head from hood.
8.
Remove arms from sleeves.
9.
Step out of socks and trousers.

Visual inspection of the chemical
protective suit
Check air-tightness of chemical
protective suit
Check air-tightness of suit valves

The interval can be extended to 2 years for chemical protective suits
that are stored in a CPS storage and transportation bag.
5.1
Visual inspection of the chemical protective suit
The following tests must be performed. If any tests are failed, the chemical
protective suit must be disposed of.
Check if the exterior of the chemical protective suit has any holes, cuts or
abrasive wear.

Check if the seam binding lifts or comes away.
Check that the face cuff is undamaged.
Check that the gloves are undamaged. In the case of chemical protective
suits with glove combinations, check the inner and outer gloves.
Check that the closure system and cover flap are undamaged. If necessary,
grease the closure system with the grease pencil.
Check that the suit valve is free and undamaged.
Check if the suit material shows any signs of wear (white lines) or ozone
damage (white chalky spots), and if the coating is coming away from the
textile fabric.
5.2
Check air-tightness of the chemical protective suit
The check is described for the Porta Control 3000 test device. It can also be
performed with other test units, although the specified values must be adhered to.
Perform the test according to ISO 17491-1 method A.2 at a constant room
temperature (20 °C ±5 °C).
The compressed air used must conform to the requirements of EN 12021.
The required test accessories are given in the order list (see Section 9 on
Page 15).
5.2.1 Preparing the test
1.
Partially inflate the test bubble and close with a hose clip.
2.
Moisten the test bubble with water and insert in the head cover of the
protective suit through the open closure system.
3.
Continue to inflate the test bubble until the face cuff fits tightly all round.
4.
Close the test bubble with a hose clip.
5.
Close the closure system.
6.
Spread out the protective suit, with the back section downward.
7.
Unfasten the protective cap from the suit valve and remove the valve disc.
8.
Fasten the double test cap onto the suit valve.
9.
Connect one connector on the test cap to the test unit via the blue hose.
10. Ensure that both valves on the black hose of the test unit are closed.
11. Connect the other connection on the test cap to the compressed air supply
(6 bar) via the black hose.
12. Carry out the test (see Section 5.2.2 on Page 13).
5.2.2 Carrying out the test
CAUTION
!
The material becomes damaged when the suit is overfilled.
When filling the chemical protective suit, ensure that the pressure
does not rise too far over the specified values.
1.
Open the blow-off valve on the black hose and fill the chemical protective
suit until the test unit shows 17.5 mbar. Close the blow-off valve.
2.
Set a settling time of 10 minutes and start the stopwatch. During this time,
keep the pressure at around 17 mbar so that a pressure and temperature
compensation can take place. Top up air as necessary.
3.
Open the vent valve. Reduce the pressure to 16.5 mbar. Close the vent
valve.
4.
Set a test time of 6 minutes and start the stopwatch.
5.
After the test time elapses, read off the pressure on the test unit.
There are no leaks in the chemical protective suit if the pressure drop is less than
3 mbar. Then disassemble the test setup and check the suit valve.
If the drop in pressure is greater than 3 mbar, check whether an error has
occurred in the test set-up. If the tests were concluded without errors, the
chemical protective suit must be disposed of.
5.3
Checking the air-tightness of the suit valve
The check is described for the Porta Control 3000 test device. It can also be
performed with other test units, although the specified values must be adhered to.
Carry out the test in accordance with EN 943-1, 6.5.1, but at 10 mbar
overpressure, at a constant room temperature (20 °C ±5 °C).
The compressed air used must conform to the requirements of EN 12021.
The required test accessories are given in the order list (see Section 9 on
Page 15).
1.
Remove the blow-off valve with plug-in coupling from the black hose.
2.
Connect the end of the hose to the test unit.
3.
Plug the pumping ball on the vent valve into the black hose so that the arrow
is pointing toward the vent valve.
4.
Moisten the valve disc with clean water and insert.
5.
Attach the test cap from outside onto the valve and connect to the test unit
via the connection hose.
6.
Open the vent valve, use the pumping ball to generate an overpressure of
+10 mbar. Close the vent valve.
