A type "A" bag is constructed from non-treated insulating fabric. No requirements are specified for type "A" FIBC's as they are not intended for use in potentially explosive atmospheres. No static protection.
- Used safely to transport non-flammable products
- There are to be no flammable solvents or gases present around the bag
- DO NOT USE to transport flammable products
Type "B" Bag
A type "B" bag is constructed from insulating fabric but has a breakdown voltage less than 4KV. This provision prevents the risk of energetic propagating brush discharges which can ignite dust-air mixture. Type "B" bags may be used in the presence of the combustible dusts with MIE of greater than 3mj but in the absence of flammable vapors of gases. Low breakdown voltage.
- Used safely to transport dry, flammable powders
- There are to be no flammable solvents or gases present around the bag
- DO NOT USE to transport flammable products
Type "C" Bag
A type "C" bag is constructed from fabrics having inter-connected conductive threads. The bag must be electrically grounded during filling and emptying.
- Used safely to transport flammable powders
- Used safely when flammable solvents or gases are present around the bag
- DO NOT USE when ground connection is not present or has become damaged
Type "D" Bag
A type "D" bag is constructed from antistatic fabric that includes static dissipative, antistatic yellow threads, this unique system is patented worldwide. Does not require grounding.
- Used safely to transport flammable powders
- Used safely when flammable solvents or gases are present around the bag
- DO NOT USE when the surface is contaminated or coated with conductive material such as water or grease
UN Bag
UN approved, or Hazardous Goods bulk bags are designed to comply with the United Nations Recommendations on the Transportation of Dangerous Materials, usually known as the "Orange Book"
UN FIBCs are certified to meet the requirements of packaging category II and III materials defined in chapter 9 of the "Orange Book"
There are six categories of IBC. This includes four types of FIBC, constituting the majority of FIBCs, which are:
- 13 H1 - PP FIBC woven, without coating
- 13 H2 - PP FIBC woven, coated without liner
- 13 H3 - PP FIBC without coating with liner
- 13 H4 - PP FIBC coated with liner
