Which one of the following statements is true about the ERNESTR guidelines?

The correct statement regarding the ERNESTR guidelines is that they emphasize the importance of quick anchor setups. In rope rescue operations, efficiency can be crucial, particularly in emergency situations where every second counts. The guidelines promote techniques that allow rescuers to establish anchor systems rapidly while ensuring safety and stability. This focus on speed is integral to effective rescue operations, making the swift setup of anchors a priority for rescuers.

The other statements do not align with the principles of ERNESTR. For instance, the guidelines do not promote a single anchor as the most effective choice; rather, they encourage using reliable systems that may involve multiple anchors for increased safety. Additionally, the emphasis is on using gear that meets or exceeds industry standards, rather than specifically recommending equipment rated under 20 kN. Lastly, multiple anchors are often advised in order to enhance the overall reliability and safety of the rescue setup, contrasting the notion that they discourage their use.
