What special considerations apply to lithium batteries transported by air?

• A. They require no special requirements
• B. They require UN numbers only
• C. They require specific packaging, labeling, documentation, restrictions on state-of-charge, and segregation requirements; use correct UN numbers and ensure no damage or defect
• D. They can be shipped as regular cargo

Answer: (C)

Lithium batteries carried by air are treated as dangerous goods because they can ignite, vent, or short-circuit if damaged, mispacked, or mishandled, so they require a comprehensive set of safeguards. The best answer reflects all the required controls: packaging that meets UN standards to prevent damage and leaks, clear labeling and handling marks, the appropriate documentation (including a Shipper’s Declaration for Dangerous Goods where required), correct UN numbers to properly identify the battery type and apply the right rules, restrictions on state-of-charge to limit energy per battery and reduce fire risk, and segregation to keep them apart from incompatible goods and reduce interaction risks. Plus, ensuring there is no damage or defect is crucial, since compromised batteries pose a much higher danger and may be prohibited or require special handling. This combination of packaging, labeling, documentation, SOC limits, segregation, UN identification, and defect exclusion is why this option is the correct, best choice.
