Lithium batteries are widely used in various applications, including electric vehicles, consumer electronics, and power tools. Due to their potential hazards, such as thermal runaway and fire, the transportation of lithium batteries is subject to specific regulations and guidelines. This article aims to provide an overview of the UN numbers assigned to lithium batteries and the regulations governing their safe shipment.
Key Facts
- Lithium-ion batteries are assigned to UN 3480.
- Lithium metal batteries are assigned to UN 3090.
- UN 3481 is used for lithium-ion batteries contained in equipment or packed with equipment.
- UN 3091 is used for lithium metal batteries contained in equipment or packed with equipment.
- The UN regulations governing the shipment of lithium batteries are aimed at ensuring their safe transportation due to their potential hazards.
- Lithium batteries are classified as hazardous materials or dangerous goods.
- The regulations include specific packaging and shipping methods to prevent batteries from coming into contact with each other or conductive surfaces.
- There are different labeling requirements depending on whether the batteries are contained in equipment, packed alongside equipment, shipped in small quantities, or shipped in very small quantities.
- The transit of dangerous goods, including lithium batteries, must be organized by people with appropriate training and knowledge or accompanied by qualified companies/experts.
UN Numbers for Lithium Batteries
The United Nations (UN) has assigned specific UN numbers to lithium batteries for the purpose of classification and regulation. These UN numbers are used to identify the type of lithium battery and its associated hazards.
UN 3480: Lithium-ion batteries
UN 3090: Lithium metal batteries
UN 3481: Lithium-ion batteries contained in equipment or packed with equipment
UN 3091: Lithium metal batteries contained in equipment or packed with equipment
UN Regulations for Lithium Battery Shipment
The UN regulations for the shipment of lithium batteries are aimed at ensuring their safe transportation and minimizing the risk of accidents. These regulations are set forth in various international agreements and guidelines, including the International Air Transport Association (IATA) Dangerous Goods Regulations and the International Maritime Dangerous Goods (IMDG) Code.
Key Provisions of the UN Regulations:
Classification: Lithium batteries are classified as Class 9 hazardous materials due to their potential for thermal runaway and fire.
Packaging: Lithium batteries must be packaged in strong and durable containers that can withstand the rigors of transportation. The packaging must prevent the batteries from coming into contact with each other or with conductive surfaces.
Labeling: Lithium battery shipments must be labeled with appropriate hazard labels, such as “Lithium Ion Battery” or “Lithium Metal Battery.” The labels must be visible and legible, and they must comply with the requirements of the applicable regulations.
Documentation: Shippers of lithium batteries must prepare and provide appropriate documentation, such as a Shipper’s Declaration for Dangerous Goods, which includes information about the type and quantity of batteries being shipped.
Training: Personnel involved in the handling and transportation of lithium batteries must receive appropriate training to ensure they are aware of the hazards associated with these batteries and the precautions necessary for safe handling.
Conclusion
The UN numbers assigned to lithium batteries and the associated regulations are essential for ensuring the safe transportation of these hazardous materials. By adhering to these regulations, shippers, carriers, and other stakeholders can help prevent accidents and protect human health and the environment.
