UN numbers on munition markings are included when applicable. Which statement is correct?

• A. Always included regardless of applicability.
• B. Not required.
• C. Only on shipping papers.
• D. Included only when applicable.

Answer: (D)

UN numbers on munition markings are included only when applicable. They identify the hazard class and the specific material as dangerous goods, informing handlers, shippers, and emergency responders of what they may be dealing with. When a munition is classified as dangerous goods under the relevant regulations and requires a UN designation, that UN number is displayed on the marking. If the item is not considered dangerous goods (for example, inert or demilitarized), there is no UN number. They aren’t required for all munition markings in every case, and they aren’t limited to shipping papers alone; marking and labeling convey this information whenever required.
