What method can be used for lowering a victim during a pole-top rescue?

Using a crossarm to lower a victim during a pole-top rescue is a practical method because it provides a stable platform and additional support for the individual being rescued. A crossarm is designed to bear weight and offers a secure means of stabilizing the victim as they are being lowered. This method allows for the safe management of the victim's descent while ensuring they remain supported and minimizing the risk of further injury.

In contrast, while available techniques such as using a ladder or a sling can assist in different scenarios, they may not provide the same level of stability and safety during the actual descent. Dropping the victim slowly to the ground is not advisable, as it poses a high risk of injury due to the sudden stop and potential for jarring impacts. Therefore, utilizing a crossarm is the preferred method for ensuring both safety and control during a pole-top rescue.
