Conductive jumbo bags

CONDUCTIVE JUMBO BAGS

Quality in compliance with European standards for use in explosive environments

Why choose conductive jumbo bags?

During the filling and emptying of jumbo bags, the material in contact with the bag walls generates static electricity. In a flammable environment, the discharge of static electricity can cause a fire. To prevent such situations, special conductive jumbo bags (known as antistatic bags) are used, designed for use in flammable environments and for flammable materials.

Two main dangers:

• Explosive materials: When explosive materials are filled into jumbo bags, the choice of the bag depends on the minimum ignition energy of the material.
• Flammable environment: A flammable environment can be caused by dust, gases, or vapors. The greatest danger comes from flammable gases and vapors.

Types of jumbo bags

• Type A: They do not have antistatic or conductive properties. Most jumbo bags in the industry are of Type A.
• Type B: Antistatic bags made from fabric that eliminates severe discharges, with breakdown voltage less than 6 KV.
• Type C (Conductive bags): These bags are fully conductive, with conductive carbon threads integrated into the fabric. All parts of the bag are connected with conductive internal resistors with a resistance of less than 107 ohms. Type C bags must be grounded during filling and emptying.
• Type D: Used instead of Type C in specific situations. The advantage of these bags is that they do not require grounding, but all personnel and equipment in their vicinity must be grounded.

Conductive film

Jumbo bags with conductive film can be of Type B or Type C. The film used must be conductive.

Marking of conductive jumbo bags

Conductive jumbo bags are marked with an additional yellow label containing relevant information.

Testing of conductive jumbo bags

Testing includes measuring breakdown voltage, conductivity of the fabric, and the sewn jumbo bag.

Risks of improper use of conductive jumbo bags

If conductive big bags, especially Type C, are not properly grounded, an explosion may occur, leading to financial losses and potential worker injuries. So far, there have been no major damages during the emptying of jumbo bags, but proper use is essential for safety.
