When passing a knot in the system on a raise, can the Dog and Tails knot be utilized?

The option indicating that the Dog and Tails knot is for lowering only is correct because this knot is specifically designed to manage the lowering process in a rope rescue system. The configuration of the Dog and Tails knot provides a reliable means to control the descent of a load by allowing for a smooth transition through the system while providing necessary friction.

In raising operations, the dynamics of the load and the manipulation of the rope differ significantly. Using this knot in a raising scenario might not yield the same control or efficiency expected, as it does not facilitate the raising of a load effectively due to its structure and purpose. Therefore, it's essential to utilize knots that are specifically designed and reliable for raising in rescue situations to ensure safety and efficiency.

Understanding the specific applications of different knots ensures effective and safe operation during rescue procedures.
