The act of detonating explosive materials joined by a shared initiation system and a single firing device is called what?

• A. Blast
• B. Deflagration
• C. Propagation
• D. Airblast

Answer: (A)

The main idea here is what you get when multiple explosive charges are connected to one initiation system and fired with a single device: it is a blast. When all the charges detonate together from one firing action, they produce one explosive event—the blast—that includes the shock wave and the effects caused by the detonation. Deflagration isn’t the right fit because it describes burning that travels through a material at subsonic speeds and without the shock wave characteristic of a true detonation. Propagation refers to the moving detonation front through the explosive after initiation, which is more about how the detonation spreads through the material rather than the single initiation event itself. Airblast describes the shock wave traveling through the air as a consequence of the explosion, not the act of detonating the charges as a single synchronized event.
