Alerts In Emergency Warning Systems

types of emergency alerts

The major emergency alert systems in use today

Emergency notification systems are designed to alert an audience to an emergency or other life-threatening or dangerous event so that people can be informed as quickly as possible so as to take appropriate steps to be safe.

When an emergency happens, there are six main types of emergency alert systems that are used to send information to people who may be affected. These are:

1. Mass notification systems

A mass notification system sends recorded messages to landline phones to alert the person who answers to a nearby situation that they should be aware of. However as landline phone use is decreasing, there are fewer recipients of these sorts of messages.

2. Wireless Emergency Alerts (WEA)

These are alerts sent from the Federal Emergency Management Agency (FEMA) as well as state and local authorities to peoples’ wireless devices, including mobile phones. Messages are sent to all cell phones in an affected geographical area.

3. SMS text systems

This system is used to send SMS text messages to numbers in a database that have opted in to receive both emergency and non-emergency communications.

4. Outdoor public warning systems

These are emergency warning systems that use stationary speakers and sirens placed throughout the community that will be activated in an emergency to warn people.

5. Color code alerts

Hospital and healthcare facilities often use color codes as part of their alert systems so they can communicate the type of emergency being experienced without alarming patients and visitors to the facility. They are a quick and easy way to let staff know what the emergency is so they can be equipped to deal with it.

Color codes sometimes vary between facilities, but these ones are usually pretty standard;

  • Code blue - life threatening medical emergency
  • Code red – a fire or a probable fire
  • Code purple or pink – a missing child or child abduction
  • Code gray – to alert security personnel that there is a dangerous person or criminal activity happening in the facility
  • Code green - the hospital is activating its emergency operations plan
  • Code orange – medical decontamination is needed such as a hazardous fluid spill
  • Code silver – an active shooter
  • Code black - bomb threat.

6. Organizational emergency alert systems

An organizational emergency alert system, such as DeskAlerts, is one that can be deployed in a business, school, healthcare facility or any other organization to communicate quickly with employees in the event of an emergency. These systems work by sending emergency communications to computers and mobile devices, using different communications channels, to alert employees to an emergency situation such as a fire, active shooter, natural disaster, chemical spill, bomb threat or other crisis.
