NOTICE
The overgloves do not have to be used. However, they offer an increased cut resistance.

The chemical protective suit can be equipped either with socks made from the same material as the suit or with boots. The socks by themselves do not provide adequate protection from mechanical stresses. The user must therefore also wear suitable safety boots which are approved to EN ISO 20345.

A cuff prevents the penetration of substances between the socks and safety boots.

The visor is provided with a scratch proof screen on the outside of the suit.

The chemical protective suit features a pocket for radio units and a push-to- talk button flap. The pocket is labelled with the type ID.

The following optional components can be fitted to the chemical protective suit:

Regulating valve PT 120 L or Air-Connect: Ventilation unit for the connection of external air supply sources to the cooling system inside the suit.
D-Connect: Bracket for additional equipment (e.g. thermal imaging camera, measuring devices, rescue loops), which can be fastenend on the left or on the right hip.
Crotch strap: for adjusting the length of the suit
Antifog visor in the suit: prevents the visor from fogging.
Manometer bracket below the visor: for fastening the manometer of the compressed air breathing apparatus in the field of vision of the protective suit wearer
Work ID numbers: for simplified identification of the work teams. Marking with a waterproof pen is possible, but not recommended.

Intended use

The chemical protective suit protects against gaseous, liquid, aerosol-based and solid hazardous substances and against infectious agents. It also protects against the incorporation of radioactive particles.

Limitations on the intended use

Certain chemicals are subject to restrictions regarding the period of use depending on concentration, state of aggregation and ambient conditions.

Use

Prerequisites

WARNING
The chemical protective suit must be used in accordance with the applicable standards and directives of the country in question.

The environmental impact must be determined prior to use, since the suitability of the chemical protective suit must be determined before its use. The chemical protective suit must only be used for suitable purposes. The user has to consider national and other requirements for the use of personal protective equipment.

Non-observance can lead to death or severe physical injuries.

Instructions on using the fastener system

The fastener system has been developed especially for the chemical protective suits. Generally, the additional seals make mobility more difficult in comparison to zip fasteners on normal clothing. To prevent creases in the fastener system, the protective suit wearer must grasp and pull the fastener system to the hood, while a second person pulls the trouser leg with the fastener system down using both hands until the fastener system is free of creases. The protective suit wearer should be standing upright when opening and closing the fastener system.

CAUTION
To avoid damage to the fastener system, both halves of the zip must be parallel and unstressed. Do not use force when opening and closing the fastener system or jerk the zipper.

Fastener systems without sufficient lubrication are more difficult to operate. This can result in damage to the fastener system. Lubricate the fastener system using the grease stick supplied by Dräger.

Opening the fastener system

Fully open the fastener system.
Always pull the zipper tab in the direction of the zipper mechanism; never pull diagonally!
Do not use force. Zip elements can become bent!
If the zipper tab gets caught, pull it back and push it forward again.

Closing the fastener system

When closing the fastener system, avoid diagonal forces on the zip.
Pull the fastener chains together by hand. Then the zip will slide more easily along the section that is being pulled together.
Foreign objects, such as shirt, jacket, threads, etc. must not be trapped between the zip elements.

Preparation for use

Preparing the chemical protective suit

NOTICE
Dräger recommends that you keep the flat bags in which the chemical protective suit was delivered for later storage purposes.

Check for leaks before using the suit for the first time in order to detect any damage due to transport. Observe the maintenance intervals thereafter (see Chap. 6.1 on Page 26).
Place the chemical protective suit flat on the ground and examine visually (see Chap. 6.2 on Page 26).
WARNING
Do not use a damaged chemical protective suit. If you do, you risk death or serious injury.
If fitted, check the function of the ventilation unit and the connection to the compressed air breathing apparatus.
Treat the full face mask visor from outside using “klar-pilot” anti-fogging gel. Use the spray “klar-pilot“ Comfort for coated mask visors. If the suit is not fitted with an antifog visor, also treat the inside of the visor.
