Which of the following is not a duty of the Surface Foreman?

The role of a Surface Foreman primarily focuses on overseeing the surface operations and ensuring compliance with safety protocols, employee instruction, and maintaining a safe work environment. While they may have a level of understanding regarding maintenance procedures, performing maintenance on machinery is generally not a primary duty associated with this position. The Surface Foreman is responsible for managing the team, ensuring they are adhering to safety rules, providing necessary instructions, and facilitating training, such as first aid, which emphasizes safety on the worksite. Posting safety rules is also an essential aspect of their responsibilities to keep everyone informed of the safety standards that need to be followed.

In contrast, performing maintenance typically falls under the responsibilities of specialized maintenance personnel or technicians who have the technical skills required to conduct such tasks safely and effectively. Therefore, this distinction highlights that maintenance duties are not inherently part of the Surface Foreman's role, identifying it as the correct choice.
