What action should be taken immediately if an oil leak is suspected?

In the case of a suspected oil leak, the most appropriate action is to contact local authorities and secure the area. This is crucial because oil leaks can pose significant environmental hazards, potentially leading to water contamination, soil damage, and health risks for nearby residents. By notifying local authorities, trained personnel can respond promptly to assess the situation, contain the leak, and begin the necessary remediation processes.

Securing the area is important to prevent people from entering the affected location, which could result in exposure to harmful substances. Taking immediate action ensures that the leak is managed effectively and reduces the risk of further escalation. Prompt reporting is a key part of responsible oil management practices and often a legal requirement, supporting both safety measures and environmental protection.

The other options suggest inaction or insufficient action that could lead to serious consequences, making them inappropriate responses to a suspected oil leak.
