What does the term "structural collapse" refer to?

The term "structural collapse" refers to a sudden loss of structural integrity, indicating that a building or part of it has failed unexpectedly, often leading to a catastrophic failure that poses significant risks to life and safety. This can happen due to a variety of reasons, such as overload, material fatigue, or catastrophic events like earthquakes or explosions.

This definition aligns with the understanding that a structural collapse is an acute and severe failure, which may result in substantial damage and potential injury or fatalities. Understanding this concept is crucial for fire fighters, as they must be prepared to respond to emergencies involving such collapses and recognize the dangers involved in navigating and operating in these environments.

While planned demolition and failing safety inspections relate to structural integrity, they are not representative of an unexpected failure occurring during normal conditions. Similarly, a minor structural failure would not be categorized as a full "collapse," which typically involves a larger and often dangerous failure of the structure.
