Life is full of surprises nobody knows what will happen in the next moment. Some times there is a moment when you get the happiness which you do not expect to get easily and some times even after a hard work you do not get the expected success. Similarly a person going on the road suddenly faces an accident and needs an immediate treatment, or due to some minor mistake your place gets fired at that moment you urgently require the help of fire brigade etc. All these accidents are unpredictable an unfortunate.
To cope with all these situations special squads are designed by the local government to provide an urgent help to the needy person. All these services are known as emergency services.
Thus an emergency can be stated as the situation which is unexpected and happens all of sudden.
