Which Class 1 explosive subcategory is described as extremely insensitive?

• A. 1.6 Extremely insensitive explosives
• B. 1.5 Very insensitive explosives
• C. 1.1 Mass explosives
• D. 1.3 Fire hazard explosives

Answer: (A)

Class 1 explosives are grouped by how easily they detonate, which guides safe handling and transport. The term extremely insensitive refers to the subcategory designed to be the least sensitive to initiation. These materials require a large amount of energy to start a detonation and are not expected to cause a mass explosion in typical accidents, making them the safest option for movement and storage under many conditions. They are distinct from very insensitive explosives, which, while also hard to initiate, can still present a mass explosion hazard. So the description aligns with the category known as Extremely Insensitive Explosives.
