What is a potential consequence of an explosion in a chemical facility?

The potential consequence of an explosion in a chemical facility includes flying debris and building collapse because such events can result from the rapid release of pressure and energy within a facility. When an explosion occurs, it generates shock waves that can cause structural failures, leading to the destruction of buildings and the scattering of debris over a wide area. This poses significant risks to both personnel on-site and individuals nearby, as the blast can propel fragments at high speeds and create hazardous conditions.

While the other options reflect possible outcomes of an incident, they are more indirect or long-term effects rather than immediate physical consequences of an explosion. Flying debris and building collapse are direct, immediate threats resulting from the dynamics of an explosion.
