What is the difference between a primary and secondary search?

The distinction between a primary and secondary search in structural collapse scenarios is crucial for effective rescue operations. A primary search involves a rapid assessment of the affected area, focusing on quickly locating any survivors who may be trapped or in need of assistance. This initial sweep is designed to maximize the chances of saving lives by swiftly identifying individuals who can be rescued.

In contrast, a secondary search is conducted after the primary search has been completed. This phase is much more thorough and methodical, allowing rescue teams to systematically locate victims and assess the overall environment for hazards. The secondary search often includes a detailed examination of the debris and may involve the use of specialized techniques and equipment to uncover additional victims or evidence of their presence.

This structured approach ensures that while immediate rescue efforts address the most urgent needs, further searches can comprehensively cover areas that may have been missed initially. The focus on different objectives during each phase helps improve overall rescue outcomes.
