What is the function of a "watchman" at excavation sites?

The function of a "watchman" at excavation sites is to alert workers to potential hazards, especially in areas where there is traffic or heavy equipment in operation. This role is crucial for maintaining safety on site because excavation work often occurs in dynamic environments where unexpected dangers can arise. The watchman's primary responsibility is to monitor the area and communicate any risks to workers, ensuring they can avoid accidents or injuries related to equipment movement or nearby vehicular traffic. This proactive measure enhances overall site safety and helps create a safer work environment for everyone present.
