You should call 911 for emergencies only. An emergency is when immediate police, fire, or ambulance assistance is necessary. When you call, be prepared to state the location of your emergency, type of emergency, your name, and your phone number.
Stay calm and be prepared to answer a list of questions concerning your emergency.
If you accidentally dial 911, please do not hang up. Stay on the line and let the telecommunicator know it was an accident.
