Emergency Evacuation Sirens have been around for over 100 years, and they’re still going strong today!
- Emergency evacuation sirens are a standard feature of most public buildings.
- They are designed to alert people in the building that it is time to evacuate and leave quickly.
- They work by emitting sound waves at a high volume, usually 120-140 decibels (dB) or more.
The Emergency Evacuation Siren is a system that warns people when an emergency has occurred.
The Emergency Evacuation Siren was first developed in 1907 by John H. Carmany to evacuate buildings during fires or other emergencies without causing panic among building occupants. These systems are now used in schools, hospitals, theaters, and many other places where large groups of people may need to be evacuated quickly in the event of an emergency such as fire or chemical spills.
