Which class is defined as Very Insensitive Explosive?

• A. Class 1.1G
• B. Class 1.2G
• C. Class 1.3G
• D. Class 1.5G

Answer: (D)

The idea being tested is how explosives are classified by sensitivity within Class 1 hazards. Very Insensitive Explosives are designated as Class 1.5, a category used for materials that are so resistant to initiation that a detonation is unlikely under ordinary handling. The “G” suffix is the compatibility group used in some regulatory systems to further specify packaging or segregation, but the key takeaway is that Very Insensitive Explosive corresponds to Class 1.5. So, the choice that identifies a Very Insensitive Explosive is the one labeled as 1.5G. The other classifications describe higher sensitivity and different hazard types: 1.1 involves mass explosion hazard, 1.2 involves projection hazard, and 1.3 involves fire hazard with no significant blast.
