Detonating Cord classifications include which of the following?

Detonating Cord classifications include which of the following?

• A. 1.1D or 1.4D
• B. 1.2D or 1.3D
• C. 0.5D
• D. 2.0D

Answer: (A)

Explosives are classified by UN hazard classes to describe how much blast potential they have and how they should be handled in shipping. Detonating cord is a blasting explosive, so it falls under Class 1 explosives. Within that class, its packaging and use can correspond to either a mass explosion hazard (division 1.1) or a minor explosion hazard (division 1.4), which is why detonating cord classifications include both 1.1D and 1.4D. The letter D indicates a specific grouping used for blasting agents in transport classifications. Other divisions like 1.2D or 1.3D describe different hazard profiles (projection hazard without mass explosion, or fire hazard with minor blast, respectively) and don’t apply to detonating cord in typical blasting applications. A designation like 2.0D corresponds to a gas hazard, which isn’t how detonating cord is classified. Thus, the correct range for detonating cord is 1.1D or 1.4D.
