In the event of a derailment, what should all persons do if the pantograph remains against the wire?

In the situation of a derailment where the pantograph is still in contact with the overhead wire, it is vital for safety that all persons adhere to specific precautions to avoid injury or accidents.

Staying at least 3 feet away from any equipment is crucial because this distance helps to minimize the risk of electrocution or electrical shock that could occur if the equipment is energized. Electricity can travel through the ground and equipment, so maintaining a safe distance is essential.

It is also important that individuals do not attempt to board equipment if they are on the ground. Approaching a derailed vehicle that may still have electrical components active can pose significant dangers, potentially exposing individuals to live wires or other electrical hazards.

Furthermore, it's imperative that no one leaves the equipment in a way that allows for simultaneous contact with both the equipment and the ground. This action, known as creating a ground path, can lead to severe electrical shock or worse because it allows electricity to travel through the body, which is extremely dangerous.

Thus, following all of these safety measures is critical during a derailment to ensure the safety of individuals near the scene. Collectively, these guidelines represent a comprehensive approach to maintaining safety, which is why selecting all of the above as the correct answer accurately
