What is one of the hazards associated with structural collapse?

Structural collapse poses various hazards that can endanger lives and complicate rescue efforts. One significant hazard associated with structural collapse is secondary collapse. This refers to the potential for additional sections of a structure to fail after the initial collapse has occurred. The instability created by the first failure can compromise other areas, leading to further threats, particularly to first responders, victims, and individuals attempting rescue operations. Understanding this risk is crucial because it highlights the need for cautious evaluation of a collapsed structure before entering or performing any tasks nearby.

In contrast, while water pooling and flooding certainly pose hazards in specific scenarios, they are more related to environmental factors rather than directly linked to the structural issues at hand. Humidity, although it might affect conditions in a collapsed area, is not considered a primary hazard of structural collapse in the same direct and critical manner as secondary collapse. Hence, recognizing secondary collapse as a key hazard helps responders prioritize safety measures during recovery operations.
