The correct answer highlights the two significant hazards associated with explosions: blast overpressure and flying debris.

During an explosion, the rapid release of energy generates a shock wave known as blast overpressure, which can cause severe damage to structures, vehicles, and even people within the vicinity. This wave can result in injuries ranging from concussions to fatal trauma due to the intense force it exerts.

Additionally, flying debris is a critical concern. Explosions can propel objects at high velocities, causing injury or destruction far beyond the initial blast area. These projectiles can be anything from fragments of buildings and vehicles to smaller items that are caught in the explosion's force, posing a severe risk to anyone nearby.

Recognizing these two hazards is essential for effective incident response and safety planning in firefighting and emergency situations where explosions are possible. The other options mention valid hazards but do not specifically address the immediate and primary dangers generated by explosions.
