What is a significant danger associated with flammable liquids during explosions?

Flammable liquids pose a significant danger during explosions because they can pool in various locations, leading to the possibility of non-seated explosions. When flammable liquids spill, they can accumulate in low-lying areas, creating hazardous conditions. If these pooled liquids are ignited, they can produce a rapidly expanding fire and potentially a powerful explosion that results from vaporization, rather than from a seated (or contained) source. Non-seated explosions often occur when the vapor from these flammable liquids ignites and expands quickly, leading to a sudden release of energy that can cause considerable damage and pose serious risks to safety.

The ability of flammable liquids to pool and generate hazardous vapor concentrations is crucial in understanding explosion dynamics. This emphasizes the importance of proper storage, handling, and cleanup protocols to mitigate risks associated with flammable liquids in various environments.
