What are defensive actions in confined space rescue?

Defensive actions in confined space rescue primarily involve conducting operations that protect rescuers from potential hazards within the space. This approach emphasizes maintaining a safe distance from the dangers present inside the confined space while still facilitating a rescue effort.

Choosing the second option reflects this concept well, as it entails performing the rescue from outside of the confined space, allowing for a safer operational posture. In this manner, rescuers can use equipment like ropes or stretchers, and communicate with victims without entering hazardous conditions directly.

Defensive actions may also involve monitoring environmental factors and preparing responses that minimize risk to the rescuers. This reinforces the importance of employing protective measures, as entering a confined space often exposes personnel to risks such as toxic atmospheres, limited mobility, and other dangers that could lead to further accidents.

The other options involve direct engagement with risks or focus on preparation rather than the safety-oriented strategies characteristic of defensive actions. These elements are less aligned with the intent of defensive operations, which prioritize the safety and effectiveness of the rescue efforts.
