A rope grab on a horizontal lifeline can cause what type of hazard?

1. Fall hazard

2. Slip hazard

3. Swing rope hazard

4. Entanglement hazard

The correct answer is: Swing rope hazard

A rope grab on a horizontal lifeline can create a swing rope hazard due to the nature of how it operates. When a worker falls while using a rope grab, it is designed to slide along the lifeline, which can cause the worker to swing away from the fall point once the grab engages. This swinging motion is not controlled and can lead to potential collisions with structures, equipment, or other workers. Moreover, this swing could also lead to loss of balance or further falls if proper safeguards are not in place. Understanding the dynamics of how a rope grab functions is essential for securing safety measures, especially in scenarios where the distance between the lifeline and potential hazards is significant. Such conditions necessitate that millwrights and other workers are trained on how to use personal protective equipment correctly and understand the risks associated with swinging during a fall arrest. This highlights the importance of fall protection planning and equipment selection in maintaining a safe working environment.
