What action should be taken if visual signs indicate an underground service?

When visual signs indicate the presence of an underground service, the appropriate course of action is to stop digging and further investigate. This is essential because underground services, such as gas lines, water pipes, or electrical conduits, can pose significant risks if damaged. Ceasing operations immediately prevents potential injury to workers, avoids damage to the underground infrastructure, and enables a thorough assessment of the situation.

Further investigation typically involves using tools and techniques to locate and identify the underground service more accurately. This can include consulting utility mapping and making use of detection devices, which ensures that the safety of the workers and the integrity of the services are maintained. It is crucial in excavating operations to prioritize safety and compliance with regulations regarding underground services, making this response the most responsible and proactive choice.
