Type D FIBC – Properties & Specifications

/13 Comments/in /by

Bulk handling of conductive or insulated materials is commonplace for industrial applications. When these materials are filled, emptied or transported, electrostatic charges develop due to the regular rough contact established between particles and container walls. These charges hold the potential of causing ignition when used in flammable atmosphere. Type D FIBC (Flexible Intermediate Bulk Container) has adequate protective elements built in it which does away the chances of combustion or other hazards.

Properties of Type D FIBC

The containers are manufactured out of anti-static and static dissipative fabrics whose strategic design prevents the formation of incendiary sparks or brush discharges. The discharges can be propagated off without requiring the bag to be connected to the ground. With Type D, safe packaging of combustible materials and handling products in combustible or flammable atmospheres becomes a breeze. It is desirable not to use the bag if its surface shows sign of contamination or is covered with grease, water and other conductive substances.

The fabric of the Type D bags is specially made to control static electricity. Electrostatic electricity is the result of the imbalance between electric charges that exists on the surface of the substance and within it. During rapid filling and discharging odd bulk bags, the fluid motion adopted by pulverized substances produces static charges when the friction between surfaces takes place and is heightened by the resistance offered by the walls of the containers. The rapid build up of the charges is hazardous and can cause the dust to become inflamed. The combustible dusts are generated within the bag during handling or may be present in the atmosphere. It is importance that you use Type D FIBC to remove or prevent electric charges as the amount of investment on your part is high.

Handling specifications

If the minimum ignition energy of the combustible dust present when bilk products are handled exceeds 1000 mega joules and is less than 3 mega joules, it is safe to use Type D bag. Type D FIBC is safe for use in non-flammable, explosive dust, gas and vapour filled atmospheres. The bag does not require grounding or earthing.

It is advisable to use Type D bags inevitably in industries that experience a high risk of electrostatic hazards, prominent among them being minerals, foods, pharmaceuticals, and chemicals.

The safety features inherent in the FIBC assists in removing inherent hazard of grounding failures which always remain present in FIBC Type C or other conductive bags. Grounding errors can occur due to manual failures. As you switch away from Type C grounded bags to Type D, you are assured of the proven safety of these bulk containers.

Conclusion

Type D bags are helpful in safe dissipation of electrostatic charges without having to make provision for grounding or earthing connection. The bags can be used with safety for both earthed as well as unearthed products. The bags are manufactured by complying with the regulations defined for usage in storing and transporting dry materials. Both coated as well as uncoated anti-static fabrics can be used for manufacturing these bags.

Transportation of granulated / flaked / powdered material is best handled using Flexible Intermediate Bulk Containers (FIBCs). Since FIBC are made of woven plastic, while emptying or filling them, electrostatic charges develop due to the contact established between particles and container walls.

These charges hold the potential of causing ignition when used in an inflammable atmosphere. Either Type B, Type C or Type D FIBC may be used for gaining protection against the risk of an explosion when handling material in an explosive environment. However, there is a difference in the degree and reliability of protection when we compare a Type B, Type C and Type D FIBC. A Type D FIBC offers greater protection and also assures higher reliability when it comes to mitigating the risk of explosion on account of development of electrostatic charges.

To determine which type of FIBC is best suited for your application it is required that you know the minimum ignition energy of the combustible dust or flammable vapour that may be present at the operating site.

Properties of Type D FIBC

Type D FIBC are manufactured out of antistatic and static dissipative fabrics whose strategic design prevents the formation of incendiary sparks or brush discharges. Unlike Type C FIBC, the electrostatic charges can be propagated off without requiring the bag to be connected to the ground. With Type D, packaging of combustible materials as well as handling of products in combustible or flammable atmospheres becomes lot easier and safe. However, care should be taken to ensure that a Type D FIBC bag is not used if its surface shows sign of contamination or if is covered with grease, water and other conductive substances.

The fabric of Type D bags is especially made to control static electricity. Electrostatic electricity is the result of imbalance between electric charges that exists on the surface of the substance and within it. During rapid filling and discharging odd bulk bags the fluid motion adopted by pulverized substances produces static charges when the friction between surfaces takes place and is heightened by the resistance offered by the walls of the containers. The rapid build up of the charges is hazardous and can cause the dust to become inflamed. The combustible dusts are generated within the bag during handling or may be present in the atmosphere. It is importance that you use Type D FIBC to remove or prevent electric charges as the amount of investment on your part is high.

Handling Specifications

Type D FIBCs can be used if the combustible dusts or flammable vapors are present or in locations that have a minimum ignition energy of 0.14 mJ. However, such Type D FIBCs are not appropriate for use with conductive powders.

It is advisable to use Type D bags inevitably in industries that experience a high risk of electrostatic hazards, prominent among them being minerals, foods, pharmaceuticals, and chemicals.

The safety features inherent in Type D FIBC assists in mitigating risk of grounding failures which comes as a part and parcel of Type C FIBC. As you switch from Type C grounded bags to Type D, you are assured of the proven safety of these bulk containers.

Food Grade FIBC: The Best Choice for Commercial Food Storage

Food Grade FIBC: The Best Choice for Commercial Food Storage

/12 Comments/in /by

FIBC stands for Flexible Intermediate Bulk Container. Usually, it is referred to as bulk bags. The size of these containers is such that they cannot be carried by hand; however, they aren’t large enough to contain a truck load of materials. FBICs are used in all kinds of industries today, including those dealing in food items.

Food Grade FIBC or Bulk Bags

Food grade FIBCs are made from FDA – approved resin, which can be used for the packing food products. These bags must be produced in a clean facility that is certified by the food safety standards, like the Safe Quality Foods (SFQ), British Retail Consortium (BRC) or the American Institute of Baking (AIB).

Bulk bags are perfect for the storage of food products like sugar, pulses, rice and other similar edible products. When it comes to products with a powdery consistency, FIBCs need to have dust-proof seams and laminated fabric or polythene lining.

Who Uses these Bags?

Bulk bags approved as Food Grade FIBC can be used for the transport and storage of spices, pulses, grains and food powders like milk powder or chickpea flour. Even pharmaceutical drugs can also be transported safely in these bulk bags.

What are the Advantages?

– Cost effective

Food grade FIBC is available for industrial use at an affordable price. Their strong quality ensures their ability to protect their contents without breaking or getting punctured. This adds to the cost effectiveness by bringing down the cost of production.

– Reuse

Bulk bags can be used more than once provided they have the 6:1 Safety Factor because these bags have been designed to be used multiple times. This in turn helps an organization to save money.

– Recyclable

The new food grade FIBCs are made from 100% virgin polypropylene. Meaning they are definitely recyclable. As a result, industries can stick to environmental-friendly ethics.

– Convenience

These bags can be stored in a very small space when not in use. They are deflated when not in use and packed away. Hundreds of them can be stored very limited space without a problem. At the same time the need for the maintenance of these bags is very low.

– Various Options

Another great advantage about food grade FIBC is it comes with multiple options to meet various requirements, like:

  • 9 lbs to 4409 lbs capacity

FIBC or Flexible Intermediate Bulk Container is a bulk bag constituted of flexible fabric. FIBC bags serves as an industrial container to store and transport dry and flowing materials like sand, fertilizer, granules of plastic etc.

Need for Type C FIBC

Industrial material handling or transportation occurs in bulk and hence FIBC are extensively used. As FIBC bags are made up of polypropylene there exists a possibility that while speedy filling or emptying takes place, there is a built up of electrostatic charges on the inner walls of FIBC. Electrostatic charges form on the surface of materials which were in close contact and are being separated. They hold the potential of igniting combustion if the surrounding environment is hazardous because of the presence of highly inflammable material. To mitigate such risks, Type C FIBC are used.

A Type C FIBC is nothing but a conductive jumbo bag which is made using conductive film tapes for the purpose of grounding the electrostatic charge that might have developed during the emptying or filling process. These bags are used in industries where the atmosphere is likely to contain explosive content which can be ignited due to the presence of electrostatic charges.

Properties of Type C FIBC Bags

The configuration of bags is done with suitably grounded interwoven conductive threads along with non-conductive polypropylene fabrics. The sewing of the bags is done in a grid pattern. A grounding point is made available on the bag that allows the bag to connect to the ground and safely dispose of the accumulated static charges. Static charges developing during filling or emptying are safely passed on to the ground. Potential of discharges is nil. To do away with grounding faults, FIBC Type C comes armed with conductive loops which establish contact with hoist system that provides safe passage of charges to ground.

Breakdown voltage is within 6kV. The bags can be safely used in an environment replete with combustible dusts, flammable vapours or gases having ignition energy levels greater than or equal to 0.14mJ.

Safety precautions

Type C FIBC bags are custom made to meet the needs of the industries. One has to keep in mind that the process of interconnecting and grounding of the container can suffer from inadvertent human errors, just like any other manual operations. Before using them, you need to ensure that the ground connection is present and it has not been damaged. If unavailable or damaged, the bags should not be used. The bags are primarily used for safe transportation of flammable powders and as such even if flammable solvents or gases are present surrounding the bag, the safety quotient is high.

When the minimum ignition energy of dust is greater than 1000 mega Joules and less than or equal to 3 mega joules, Type C bags can be used in non-flammable, explosive dust and explosive gas or vapour atmospheres.

Type C FIBC dissipates static electricity, keeps away brush discharges, and prevents sparks/ PBDs. The one thing you need to keep in mind is that you should ground the FIBC properly. Just a little carefulness on your part assures long term safety.

At Rishi FIBC you can place order for customized high quality Type C bags. Rishi FIBC Solutions Pvt Ltd is an export oriented undertaking offering wide range of FIBC bags to suit the varying needs of the industry.
