What is the purpose of a handline in rescue situations?

A handline is a crucial tool in rescue situations, primarily designed to assist in lowering or securing a victim. Its flexible nature allows rescuers to easily maneuver and control the descent of a person, ensuring their safety during a rescue operation. The ability to secure a victim properly is essential to prevent further injury and to provide stability as they are extracted from a hazardous environment.

In rescue scenarios, the other options serve specific but different purposes. Tying off rescue equipment typically requires more specialized rigging techniques and gear, while lifting heavy tools or securing aerial devices involves equipment that is better suited for those tasks. This distinction highlights the handline's role in direct victim support, making it an indispensable component during rescue efforts.
