Which class includes pyrotechnic devices such as fireworks and ammunition?

• A. Class Seven - Radioactive Material
• B. Class Three - Flammable Liquids
• C. Class One - Explosives
• D. Class Two - Gases

Answer: (C)

Pyrotechnic devices such as fireworks and ammunition are energetic materials designed to release energy rapidly. That sudden energy release can produce a blast and fragmentation, which is the hallmark of explosives, so they are classified in the explosives category. Other classes cover different hazards—gases involve compressed or liquefied gases, flammable liquids are capable of ignition but aren’t meant to explode, and radioactive materials deal with ionizing radiation. Because these devices are built to explode or detonate and cause a violent energy release, they belong in the explosives class.
