A safety line is a type of rope or cord used to provide security and prevent accidents in various activities, such as climbing, construction, or rescue operations. It is typically anchored to a stable point and allows individuals to secure themselves or equipment, reducing the risk of falls or injuries. In climbing, for example, a safety line is often attached to a harness and connected to a fixed point, ensuring that climbers remain safe while ascending or descending. Safety lines are essential in many industries, including construction, firefighting, and search and rescue, where safety is a top priority.
