If you’re currently using FIBCs to transport/store hazardous materials, chances are you’re already using UN bulk bags. If you’re not, then read this blog and find out if UN bags are a good fit for you.
UN bags are specifically designed to store/transport hazardous materials. In order to safely use the bags, the UN has outlined specific criteria for identifying the bags and their contents.
UN FIBC Bulk Bag Standards
It’s easy to visually identify a UN bag because of the strict labeling and ID requirements. Part of these strict labeling requirements relate to the contents of the bag. Because UN bags are designed specifically to carry hazardous materials, it’s paramount to proper safety that the bag is labeled with a specific hazardous materials label that pertains to what’s in the bag.
There are 8 different classes of hazardous labels on UN bulk bags:
- Class 4.1: Flammable solids, self reactive substances and desensitized explosives
- Class 4.2: Substances liable to spontaneous combustion
- Class 4.3: Substances that emit flammable gases when they come in contact with water
- Class 5.1: Substances that oxidize
- Class 5.2: Organic peroxides
- Class 6.1: Toxic substances
- Class 8: Corrosive substances
- Class 9: Miscellaneous dangerous substances and articles
ID Break Down
On top of specific labeling identifying the contents of the UN bulk bag, UN bags use a unique bag labeling system that allows the user to track the origin, materials, manufacturer, coating, and other important attributes of the individual UN bag. This labeling system is extremely important to safe handling, filling, and use of a UN bag given the hazardous nature of a UN bag’s contents.
Below is a breakdown of what the bag label looks like as well as the significance of each individual tag:
- United Nations Packaging Logo - 178.503(e)(1)(ii)
- Code number designating FIBC design type - 178.702(a)
- Capital letter identifying the performance standard under which the design type has been successfully tested
- The numerical month and year of manufacture
- Country authorizing allocation of the mark - 178.503(e)(1)(ii)
- The name and address or symbol of the manufacturer or the approval agency certifying compliance with subpart N and subpart O of 178
- The stacking test load in kilograms
- Maximum gross mass
