What are the three main types of anchors used in rope rescue?

The correct answer identifies the three main types of anchors utilized in rope rescue: passive, active, and movable anchors. Understanding these categories is crucial for effective rescue operations.

Passive anchors rely on a stable and secure environment, such as a tree or a boulder, that is not altered during the process. They provide a reliable point from which rescuers can operate without necessitating any alterations to the surroundings.

Active anchors involve equipment, such as bolts or other hardware, which are placed into the environment to create secure attachment points. These anchors might require more meticulous installation and assessment but offer flexibility in various scenarios.

Movable anchors are adaptable in nature and can be repositioned during operation. This type of anchor is particularly useful in dynamic rescue environments where conditions may change, requiring adjustments to the anchor's position or configuration.

The other options describe anchors in terms that do not align with standard terminology in rope rescue practice. They may refer to other concepts or characteristics of anchors but do not encapsulate the primary classifications used in the context of rope rescue. Understanding these categories helps rescuers choose the most effective anchoring technique for specific situations, ensuring safety and efficiency during rescue operations.
