Which of the following is a safety measure when working around excavation sites?

Using barriers and marking boundaries is crucial for ensuring safety around excavation sites. This practice establishes clear physical boundaries that prevent unauthorized access and keeps personnel at a safe distance from potential hazards associated with excavation work. Barriers help to protect workers and passersby from falling into open excavations or being struck by equipment. Additionally, marking boundaries makes the site aware to everyone, reducing the risk of accidents and injuries.

This method aligns with safety regulations and best practices in construction and excavation operations, emphasizing the importance of creating a secure work environment. The implementation of barriers and marked boundaries also aids in clearly defining the scope of the work area, which is essential for effective communication among workers and management regarding site safety.
