Explosives 1.1D are described as which of the following statements?

Explosives 1.1D are described as which of the following statements?

• A. Sensitive to initiation by blasting caps
• B. Dynamite, watergels, and emulsions included
• C. Stable and safe
• D. Not used in blasting

Answer: (A)

1.1D explosives are a high-hazard category defined by their potential to cause a mass explosion if initiated. The key point here is how readily they can be set off: they are sensitive to initiation by a small initiating device, such as a blasting cap. That sensitivity to initiation is what makes this description the most accurate. The other statements miss the defining trait: these materials are not described by a fixed mix of dynamite, watergels, and emulsions, nor are they stable and safe or not used in blasting. In blasting operations, such materials are handled under strict controls because their very nature is dangerous and designed for controlled initiation, not safe or everyday use.
