Which individual is responsible for monitoring safety when lifting personnel near power lines according to regulations?

The individual responsible for monitoring safety when lifting personnel near power lines is the dedicated and qualified signal person. This role is critical because the signal person is specifically trained to understand the complexities and hazards associated with crane operations, especially when working in proximity to power lines. They ensure that the lifting operations are conducted safely and that all necessary precautions are taken to mitigate risks associated with electric shock or interference from high-voltage lines.

The signal person's responsibilities include communicating with the crane operator and other crew members, ensuring that everyone is aware of the hazards present, and implementing safety protocols to avoid accidents. Their training equips them with the knowledge of safe distances from electrical lines, proper signaling techniques, and emergency procedures, all of which are essential for maintaining a safe work environment.

In contrast, the other roles such as the site manager, safety representative, and field engineer, while also important for overseeing safety and operations on a construction site, do not have the specific training and focus on the direct coordination and signaling that a dedicated signal person possesses when it comes to lifting tasks near power lines.
