Which hazard is one of the two greatest hazards to explosives?

• A. Water exposure
• B. Excessive heat
• C. Vibration
• D. Radiation

Answer: (B)

Excessive heat is the biggest hazard to explosives because heat raises the energy inside the material and can accelerate decomposition until it detonates, especially when the material is confined or in bulk. In storage, heat sources include sunlight, hot equipment, nearby fires, or chemical heat from reactions, all of which can push explosives toward initiation far more reliably than other factors. Water exposure can cause moisture-related degradation or corrosion in some formulations, but it doesn’t universally trigger rapid initiation. Vibration might contribute to movement or friction, yet it is typically less capable of causing initiation than a significant heat source. Radiation isn’t a practical risk factor in standard explosive storage. Overall, excessive heat is one of the two greatest hazards because of its direct and widespread potential to trigger dangerous energy release.
