You drive a rail vehicle. How will you behave when you notice a fire in the electrical installation?
Explanation
Correct answer: I will stop the vehicle, open the door to evacuate the passengers, disconnect the pantograph from the rail grid and proceed to extinguish the fire.
The correct procedure in the event of an electrical system fire requires, in the first instance, stopping the vehicle and ensuring the safety of passengers by opening the doors for evacuation. The key step, which must be taken before attempting to extinguish the fire, is to disconnect the power supply by lowering the pantograph, as this eliminates the source of the fire and prevents the risk of electric shock. Acting in this sequence maximises the safety of all persons and the effectiveness of the firefighting action.
