Why is it important to maintain proper access and egress to an excavation site?

Maintaining proper access and egress to an excavation site is crucial primarily to ensure that workers can enter and exit safely, especially in emergency situations. An excavation site presents various hazards, and quick evacuation can be life-saving if an accident occurs or if conditions suddenly change, such as an impending collapse or hazardous materials exposure. Properly designed access and egress points help workers to move efficiently without unnecessary risk, allowing for a structured and rapid response in case of emergencies. This focus on safe entry and exit points is a key aspect of excavation site safety, reinforcing the importance of preparedness and risk management in potentially dangerous work environments.
