Which of the following increases the potential hazard of an explosion?

A higher blast wave impulse increases the potential hazard of an explosion because it refers to the energy and force transmitted through the air in the form of a shockwave when an explosive event occurs. This impulse can cause significant destruction and potentially harm individuals in the vicinity. A greater blast wave impulse means that the energy is released more forcefully, which leads to a wider area of impact and increased risk of injury or damage.

In contrast, lower turbulence typically indicates a more stable environment wherein the explosion's effects may be dampened, rather than intensified. Reduced temperature often leads to lower energy reactions, which can lessen the severity of an explosion. Increased distance from the source of the explosion decreases the potential hazard, as the impact and energy dissipate over distance, making it less likely for nearby individuals or structures to be affected. Thus, it is the higher blast wave impulse that directly correlates with an increase in explosion hazard.
