• C. 6
• D. 7

Answer: (C)

Class 1, which pertains to explosives in the framework of dangerous goods classifications, is subdivided into six distinct divisions. Each division is designated for different categories of explosives, based on their characteristics and risks associated with their use and transport. The six divisions are as follows: 1. Division 1.1 - Explosives with a mass explosion hazard. 2. Division 1.2 - Explosives with a projection hazard but not a mass explosion hazard. 3. Division 1.3 - Explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard. 4. Division 1.4 - Explosives that present no significant hazard. 5. Division 1.5 - Very insensitive explosives which have a mass explosion hazard. 6. Division 1.6 - Extremely insensitive articles that do not have a mass explosion hazard. Understanding these subdivisions is crucial for compliance with regulations and ensuring safety in handling, transport, and storage of explosive materials. The accurate differentiation among these divisions helps first responders, transporters, and handlers to evaluate the necessary precautions and emergency procedures tailored to the specific characteristics of the explosives in question.
