What action is critical when pulling cables to ensure safety and efficiency?

Maintaining two-way communication is critical when pulling cables because it enhances safety and coordination among team members. Effective communication ensures that everyone involved is aware of their roles and any potential hazards. It helps synchronize movements, especially in a work environment where cables can be heavy and cumbersome. Without clear communication, missteps can occur, increasing the risk of accidents or damage to the cables.

While the other actions may have their merits, they do not adequately address the specific safety and efficiency needs during the cable pulling process. For instance, using hooks can improve grip, but it does not account for the need to communicate status or changes in direction or tension. Similarly, employing extra workers could enhance manpower, but without effective communication, it could lead to confusion or accidents. Using electric drills is not relevant to the cable pulling process and can introduce additional safety hazards. Thus, effective communication is paramount in ensuring that the process runs smoothly and safely.
