What is one method to build enough friction during a pole top rescue?

Building enough friction during a pole top rescue is crucial to safely lower the victim without causing further harm or losing control of the descent. Wrapping the rope twice around the crossarm increases the surface area in contact with the rope, which enhances friction and provides better control when lowering the victim. This method effectively secures the rope and allows the rescuer to manage the descent speed more effectively, thereby ensuring a safer operation.

In contrast, wrapping the rope around the victim could create a high risk of injury and is not a secure method of controlling the descent. Using adhesive tape on the rope is not a standard practice in rescue operations, as it would not provide the necessary friction or control and could lead to complications in the rescue process. Positioning the block at ground level does not contribute to friction at the pole top and would likely complicate the rescue effort rather than assist. Therefore, wrapping the rope twice around the crossarm is the most effective method for increasing friction during a pole top rescue.
