When disaster strikes, it’s crucial to know when and when to take shelter until the threat has ended. Not all sirens mean evacuation is necessary or required but evacuation sirens are very important to the health and safety of the public and require specific actions by residents after a siren has sounded.
The tone of an evacuation siren is long, high, and solid. The sound generally starts low and slowly rises to a high tone and volume. Emergency Evacuation Sirens are sounded to alert citizens to a hazard, such as a tornado or chemical spill. After the siren has sounded, citizens should shelter in place and wait for further instructions through TV or radio.
Evacuation sirens are extremely important as the first line of defense of natural and man-made disasters, and they play a crucial role for people who live in rural areas where tornados are common.
