TT Brief - lithium-ion batteries

Lithium-ion batteries, essential in devices from smartphones to electric vehicles, pose significant risks if not handled correctly. They are generally safe; however, improper treatment can lead to thermal runaway, a reaction that can cause fires, toxic gas emissions, and explosions. Transportation and logistics operators must be well-versed in the safety protocols surrounding these batteries, including national and international regulations.

Key actions include ensuring proper cargo declaration and documentation, particularly a Dangerous Goods Declaration (DGD) and Packing Certificate that meet regulatory compliance, even for smaller batteries. It's crucial to verify that manufacturers accompany batteries with required test summaries as per UN guidelines, and that they feature short-circuit prevention measures.

Operators should assess the state of charge and expected ambient temperatures for storage and shipment. When packing, care must be taken to prevent damage and ensure strong, compliant packaging, to withstand impacts during transit. The stowage of lithium-ion batteries aboard ship should adhere to the carriers’ strict segregation and stowing practices, isolating them, where possible, from other hazardous materials.

Emergency protocols are essential; fire risk assessments and effective firefighting systems should be in place to manage potential incidents. Regular training for all personnel in handling these batteries, alongside engaging in emergency drills, is vital to ensure preparedness for any unforeseen circumstances. The overarching goal is to safeguard against the hazards posed by lithium-ion batteries through thorough training, precise handling, and adherence to regulatory frameworks.

Key takeaways

• Lithium-ion batteries can cause fires and explosions if mishandled.
• Proper training and compliance with regulations are crucial for safety.
• Emergency protocols should be regularly reviewed and practised.
