A shipper must complete the dangerous goods declaration in which language?

• A. French
• B. German
• C. English
• D. Spanish

Answer: (C)

The main idea is that dangerous goods documentation for air transport is standardized so everyone reads the same information in a single language. The shipper’s declaration must be completed in English because English is the international language used in aviation, ensuring clear and consistent understanding by airlines, handling agents, and authorities worldwide. This eliminates misinterpretation of critical details such as the UN number, proper shipping name, hazard class, and packing group. Translations into other languages may accompany the declaration, but the English version is the official one used for regulatory checks and safety decisions.
