What is the purpose of using a safety harness when climbing?

Using a safety harness when climbing serves the primary purpose of ensuring safety while engaging in activities at heights. A safety harness is designed to secure the climber and mitigate the risks associated with falling. When a climber uses a safety harness properly, it can distribute the forces experienced during a fall across the body, thereby reducing the likelihood of severe injuries that could occur from a sudden drop.

Moreover, safety harnesses often connect to other safety equipment, such as ropes and carabiners, creating a comprehensive safety system that can prevent falls or safely catch a climber if a fall occurs. While the harness may indirectly assist in carrying gear and can affect speed, these are not its main functions; the sole focus of a safety harness is to maximize the safety of the climber during ascent.

In summary, the rationale for wearing a safety harness is fundamentally about preserving life and preventing serious injuries while climbing, making it an indispensable tool in climbing safety protocols.
