What must be done before excavating in an area where pipelines may be present?

Before excavating in an area where pipelines may be present, notifying utility companies for underground line location is essential. This process is often referred to as "digging safety" or "call before you dig." Utility companies utilize various techniques, including maps and physical locating, to identify the precise locations of underground utilities, including pipelines. This step is crucial to prevent accidental damage to pipelines, which can lead to hazardous situations, including leaks or explosions.

The practice ensures that any potential risks are mitigated and that the work can be carried out safely and with compliance to regulations. It also helps to protect the workers involved in the excavation as well as surrounding communities. While other options may involve safe practices or necessary permits, they do not directly address the immediate need to locate existing utilities before starting any excavation work.
