Under what condition may authorized persons perform emergency excavation or demolition?

Authorized persons may perform emergency excavation or demolition primarily to protect life, health, or property. This condition underscores the critical nature of safety and the preeminence of human life in operations involving potential hazards, such as those associated with pipelines. When an immediate threat arises—such as a leak, a fire, or other dangerous scenarios—action must be taken swiftly to mitigate risks and prevent further harm.

The urgency dictated by emergencies necessitates rapid intervention, which often bypasses standard procedures that govern routine work. Therefore, the priority is on addressing the immediate risks to ensure the safety of individuals and the surrounding environment, justifying the emergency excavation or demolition actions taken by authorized personnel. In contrast, the other options relate to non-emergency situations and do not meet the criteria for immediate risk intervention.
