What type of rescue technique is used for victims in narrow or confined spaces?

The correct answer is focused on the specific type of rescue technique tailored for situations involving victims in narrow or confined spaces. Confined space rescue techniques are designed to address the unique challenges and hazards associated with these environments, such as limited access, poor visibility, and potential atmospheric dangers. These techniques prioritize the safety of both the victim and the rescuers, ensuring appropriate measures are taken to navigate the tight confines effectively. Rescuers are trained to use specialized equipment and methods suited to reach and extract individuals from areas that are not easily accessible.

In contrast, standard high-angle and vertical rescue techniques largely apply to situations involving significant elevation changes, where victims may be suspended in the air or in positions requiring specific rigging and lowering systems. Non-restrictive rescue techniques indicate a lack of constraints but do not specifically address the complexities involved in confined spaces. Hence, the focused nature of confined space rescue techniques makes them the best choice for this scenario.
