What equals an explosive event in HME?

What equals an explosive event in HME?

• A. High pressure release only
• B. Fire and water cooling
• C. Proper mixture, containment, ignition source
• D. Moisture addition and sealing

Answer: (C)

An explosive event requires a rapid, energy-releasing reaction that is triggered inside a confined space with a suitable fuel–oxidizer mix. All three elements must be present: a proper mixture so enough reactive material is available, containment to trap the reacting gases and build high pressure quickly, and an ignition source to start the reaction. When these elements line up, the system can undergo a violent, explosive release. The other options only mention one aspect or describe conditions that would suppress or fail to produce an explosion, rather than providing the full combination needed.
