Structural integrity for bulk hazardous chemical shipments

Packaging and transportation of hazardous chemical materials require a certain number of test to be done. An intermediate Bulk Containers are widely used for packaging and shipping bulk materials. For dry refined hazardous materials are packaged inside Flexible Intermediate containers or FIBC super-sacks, which are widely used in the chemical industry for bulk handling of powders, granules, and specialty materials. These materials require packaging solutions that ensure containment, integrity, electrostatic safety, and compliance with DOT hazardous material regulations. This paper explores advancements in FIBC super-sack designs and specifications that include different fabric thickness, different liner materials, and UN- certified configuration that will be used for sensitive chemical compounds. A comparative analysis of two different specifications will help us to determine the possible cost savings. The proposal of the project is to develop the best packaging solution for packaging hazardous chemicals. This paper examines the regulatory requirements and technical standards for UN-rated Flexible Intermediate Bulk Containers (FIBCs), commonly known as super sacks, used to transport hazardous chemicals in Packing Groups II and III. It provides an overview of classification systems, performance criteria, and compliance obligations under international and U.S. regulations. For shipping hazardous chemicals materials, UN testing is required to check if the packaging can hold the type of hazardous material. After careful testing of the material to be shipped we found out the DOT requirement for these materials. If the test says hazardous material, then the material is classified as class 9 which will require UN certification for shipping hazardous chemicals. This proposal highlights the use of two different specifications of FIBC super-sacks. The two FIBC super-sacks specifications were selected for their robust working loads. There are two different thick body fabrics used for testing. The difference in cost was also the motive for selecting a lower and a higher GSM bag. By doing a PG3 UN test on both specifications, we can determine if the lower specification bag passes then in turn, it will be cheaper than the higher specification bags for packaging the rare earth hazardous substance. The type of bag used for this test is U- shaped, 4-panel bags. Inlet selected is a duffle top with 3mil Polypropylene. The body fabric is white, and the safe working load is set to 2500lbs. If both bags survive PG 3 testing, then it will help us to order lower specification bag that lower the bag cost. For PG3 testing, we will be using Title 49 CFR for test references. The regulation for testing will be used under Part 178 subpart O which mentions testing of IBCs.
