When an excavator is parked on or extends into an access way, it is crucial to implement comprehensive safety measures to protect both the operators and the public. The correct answer emphasizes the importance of using lights, signs, and barricades, which collectively serve to enhance visibility and generate awareness among pedestrians and vehicles, reducing the risk of accidents.

Lights help to ensure that the presence of the excavator is visible even in low-light conditions, making it safer for passing traffic and pedestrians. Signs provide crucial information about the potential hazards associated with the work site, alerting individuals to proceed with caution or to avoid the area entirely. Barricades serve as physical barriers to redirect traffic and keep unauthorized personnel away from the work zone.

The combination of these three elements creates a robust safety protocol, making it clear to everyone in the vicinity that they should be aware of the work being performed and the need to navigate around the equipment safely. Other options may lack one or more of these critical components, which can compromise overall safety in situations where large machinery is operated in proximity to public access ways.
