Ammo CDC Module 1 Practice Test

Items classified under explosive class/division 1.2 are characterized by having a significant hazard from projection but a limited hazard from mass explosion. This classification includes munitions that are primarily designed to be fired, projected, or thrown, and are less likely to cause a mass explosion compared to other classes of explosives. The 20 mm and 30 mm ammunition fits this description as they are typically used in military applications, such as in aircraft cannons or anti-armor roles, where they are designed to travel at high velocities and cause damage upon impact without posing a risk of mass detonation.

In contrast, hand grenades and live bombs, while they may cause localized explosions, fall into different categories of explosive devices primarily due to their design and intended use. Hand grenades are considered under different divisions as they are designed for immediate proximity effects rather than projection over distance. C4 explosives are classified as demolition explosives, which have properties that are distinct from class/division 1.2 munitions due to their potential for mass detonation and broader hazard profiles.

Thus, the correct answer identifies ammunition types that align with the specific risk classifications within explosive handling regulations.
