Which of the following is a primary feature of the One-Call System?

The primary feature of the One-Call System is that it protects underground utility lines. This system is designed to facilitate communication among various parties involved in construction and excavation activities. When excavation is planned, individuals or companies make a call to the One-Call center, which then notifies utility companies of the intended excavation. This helps ensure that the locations of underground utility lines are marked before any digging occurs, reducing the risk of accidental damage to these lines.

The protection of underground utilities is crucial for safety, as striking a utility line can result in dangerous situations, such as gas leaks or electrical hazards. Additionally, it helps prevent costly repairs and service interruptions. Therefore, the One-Call System plays a vital role in maintaining safety standards in excavation work by ensuring that all parties are informed and can take appropriate precautions.
