911 คือ ใครและบทบาทของเขาในสังคม


September 11, 2001, was a tragic day in the history of the United States. The 9/11 attacks, also known as the September 11 attacks, were a series of four coordinated terrorist attacks carried out by the terrorist group Al-Qaeda on the United States. The attacks resulted in the deaths of nearly 3,000 people and caused significant damage to several buildings, including the World Trade Center in New York City.

In the aftermath of the attacks, the role of 911, the emergency telephone number in America, became crucial. This article discusses who and what 911 is, and its significant role in society.

Who is 911?

911 is the number that people call to request police, fire, or emergency medical services in the United States. In Canada and a few other countries, the same number is used for emergency services.

The idea of an emergency number system in America began in the late 1950s, when the National Association of Fire Chiefs recommended that a single number should be established nationwide for reporting fires. After that, the Federal Communications Commission (FCC) recommended that the digits 911 be designated as the emergency telephone number throughout the United States, and that recommendation was adopted in 1968.

The beginnings of 911 were slow, with only 1% of the American population having access to the service within a few years. However, it became more widespread in the 1970s, and expanded to all areas by the 1980s.

Role of 911 in Society

The role of 911 in society is to provide a means for people to call for help in emergencies. By providing a single number to call for a range of emergency services, 911 simplifies the process of getting help when it’s needed most.

When someone calls 911, the operator answers and asks the caller what their emergency is. Depending on the situation, the call may be routed to police, the fire department, or emergency medical services. The operator will also ask for the caller’s name and location to ensure that help reaches them as quickly as possible.

911 dispatchers are trained to handle high-pressure situations and provide instructions to callers to keep them safe until help arrives. They are also trained to identify and prioritize emergencies and dispatch the appropriate resources to each situation.

911 and the September 11 Attacks

On September 11, 2001, the role of 911 became crucial. As the attacks unfolded, people in the World Trade Center and the surrounding areas called 911 for help.

The New York City 911 system was overloaded with calls, with some callers waiting on hold for several minutes. Despite the challenges, 911 dispatchers stayed calm and did their best to provide assistance to those in need.

In the aftermath of the attacks, 911 dispatchers continued to play a critical role in coordinating response efforts. They worked tirelessly to assist first responders and ensure that resources were deployed where they were needed most.

Today, 911 remains a vital part of emergency response in the United States. It has become a symbol of hope and resilience, reminding Americans that in times of crisis, they can count on each other to come together and help one another.


1. What happens if I call 911 by accident?
If you call 911 by accident, don’t hang up. Instead, stay on the line and explain to the operator that you called by mistake. This will prevent emergency responders from being dispatched to your location unnecessarily.

2. Can I call 911 for non-emergency situations?
No, 911 should only be used in emergency situations. For non-emergency situations, you should contact your local police or fire department directly.

3. What should I do if I’m unable to speak when I call 911?
If you’re unable to speak when you call 911, the operator will assume that you’re in danger and dispatch emergency services to your location. If possible, try to make a noise or tap the phone to indicate that you need help.


911 is an essential service that plays a critical role in society. It provides a single number to call for emergency services, simplifying the process of getting help when it’s needed most. The September 11 attacks demonstrated just how important 911 is in times of crisis, and how it enables people to come together and help one another regardless of the circumstances. Today, 911 remains a vital part of emergency response in the United States, providing hope and support to communities across the country.
