What is one primary characteristic of deflagration compared to other explosive reactions?

• A. It cannot be contained
• B. It travels faster than sound
• C. It occurs at subsonic velocities
• D. It does not produce a shock wave

Answer: (C)

Deflagration is characterized by the fact that it occurs at subsonic velocities. This means that the combustion or explosive reaction propagates through the explosive material at a speed slower than the speed of sound. In this type of explosive reaction, the pressure front moves through the material at a rate that is constrained by the reactions occurring in the material itself, rather than generating a shock wave. As a result, deflagration produces high temperatures and pressures but does not produce the instantaneous shock wave that is characteristic of detonation, which occurs at supersonic velocities. This key distinction is essential for understanding how different explosive reactions behave, especially when analyzing safety measures and risk assessment related to explosion hazards. By recognizing that deflagration travels at subsonic speeds, one can appreciate its different behavior and implications in explosive scenarios.
