At Fire extinguishing station;

Fire chief to trainee young man: Suppose we have only one fire-engine at the station.. An emergency call comes. I take that only Fire-Engine with me to extinguish the fire....
Another emergency call comes, you are alone in the station at duty, and there is no other Fire-Engine...What will you do?
Trainee man: Sir, After I receive the call, I shall inform you over the wireless. Then I shall take a Taxi and reach the location. Then, sir, I will do my best that fire is not extinguished till you arrive with our only fire-engine.
