What must be used to climb over an obstruction when working as a Qualified Electrical Worker?

When working as a Qualified Electrical Worker, a secondary or positioning lanyard is essential for safely climbing over an obstruction. This equipment provides additional safety by ensuring that the worker is securely attached to a stable structure or support while navigating around or over obstacles. The secondary lanyard acts as a backup in case the primary means of securing oneself fails, thus reducing the risk of falls during such maneuvers.

Using a secondary lanyard allows electrical workers to maintain a safe position and prevents uncontrolled movements or slips that could occur when attempting to traverse over obstacles, ensuring their safety and the integrity of their work environment. While other options may provide safety or reach, they do not fulfill the specific requirement for securely climbing over obstructions.
