Which is the first basic step in performing a special rescue in a safe, effective, and efficient manner?

The first basic step in performing a special rescue in a safe, effective, and efficient manner is preparation. This step is critical because it involves gathering the necessary knowledge, equipment, and resources before engaging in any rescue operation. Preparation includes understanding the specific type of rescue to be conducted, identifying potential hazards, and ensuring that all personnel involved are trained and equipped for the tasks at hand. Having a detailed plan and being mentally prepared significantly enhances the safety and success of the operation, as it allows rescuers to anticipate challenges and act decisively.

Although size-up is also essential, as it involves assessing the situation upon arrival at the incident scene, it typically follows the preparation phase. Similarly, response and assessment are pivotal components of the rescue process but occur after the preparatory measures are complete. Proper preparation lays the groundwork for effective decision-making and efficient action during the rescue, making it the foundational step that enables all subsequent actions to unfold smoothly.
