Which precaution applies specifically to lithium batteries transported by air?

• A. Segregation requirements
• B. No restrictions
• C. Must be fully discharged
• D. No labeling

Answer: (A)

Lithium batteries carry with them a unique fire risk in flight, so air transport uses segregation as a primary precaution. Segregation means keeping lithium battery shipments physically separate from other cargo that could ignite or be affected by a fire, and keeping batteries apart from each other within the cargo space. This separation helps prevent a small incident with one battery from escalating into a broader in-flight hazard, and it aligns with the tight safety controls used on aircraft.

This is why segregation is the best answer: air regulations specifically mandate this separation to manage the risk of thermal events in the confined environment of an aircraft. Other statements aren’t correct for air transport: there are indeed restrictions and labeling requirements for lithium batteries, and while there are state-of-charge considerations, there isn’t a blanket rule that batteries must always be fully discharged.
