In an emergency, call 9-1-1 or your local emergency number immediately from any wired or wireless phone. An emergency is any situation that requires immediate assistance from the police, fire department or ambulance department.
A Crime, especially if in progress
A Car Crash, especially if someone is injured
A Medical Emergency, such as someone who is unconscious, gasping for air or not breathing, experiencing an allergic reaction, having chest pain, having uncontrollable bleeding, or any symptoms that require immediate medical attention
Important: If you are not sure whether the situation is a true emergency, officials recommend calling 911 and letting the call-taker determine whether you need emergency help.
When you call 911, be prepared to answer the call-taker's questions, which may include:
The Location of the Emergency, including street address
The Phone Number you are calling from
The Nature of the Emergency
Details about the Emergency, such as physical description of a person who may have committed a crime, a description of any fire that may be burning, or a description of injuries or symptoms being experienced by a person having a medical emergency
Remember, the call-taker's questions are important to get the right kind of help to you quickly.
Be prepared to follow any instructions the call-taker gives you. Many 911 centers can tell you exactly what to do to help in an emergency until help arrives, such as providing step by step instructions to aid someone who is choking or needs first aid or CPR.
Don't Hang Up
Finally, do not hang up, until the call-taker instructs you to.
If you dial 911 by mistake, or if a child in your home dials 911 when no emergency exists, do not hang up - that could make 911 officials think that an emergency exists, and possibly send responders to your location. Instead, simply explain to the call taker what has happened.
