(HealthDay News) -- Some 240 million calls are made to 911 in the United States each year, says the National Emergency Number Association.
If you or a loved one needs law enforcement, firefighters or emergency medical help, call that number right away.
NENA shares these do's and don'ts for calling 911:
Do call for true emergencies. If you are unsure if it's an emergency, still call.
Do your best to stay calm and answer all questions.
Do know the location of the emergency.
Do post your home address number clearly.
Do not just hang up the phone if you call 911 by accident.
Do not prank call 911. In most states, this is illegal.
