From 911.gov:
In an emergency, call 911 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. Examples include:
• A fire
• 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 other symptoms that require immediate medical attention
Important: If you’re 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 the street address
• The phone number you are calling from
• The nature of the emergency
• Details about the emergency, such as a 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
