Which phase of structural collapse occurs first in the order of operations?

The phase that occurs first in the order of operations during a structural collapse is the survey of the area and assessment of hazards. This initial step is critical for the safety of all personnel involved in the rescue operation. Conducting a thorough assessment allows responders to identify potential dangers such as unstable debris, hazardous materials, or the risk of further collapse, which can significantly compromise the safety of both victims and rescuers.

By understanding the environment they are working within, responders can develop a strategic plan for subsequent operations, such as how to effectively access voids where victims may be trapped, or the safest methods for debris removal. This proactive approach is essential in ensuring that operations proceed safely and effectively.

If the survey phase is overlooked or rushed, it could lead to dangerous situations, making it challenging not only for rescuers but also for the victims trapped under the debris. Consequently, the survey of the area and assessment of hazards serves as the foundation for all following actions during incident response in a collapse scenario.
