Behavior in case of a chemical accident
What is a siren?
The siren is installed in an enterprise liable to be affected by a major accident and in endangered areas to alert of the danger.
Listen to the hazard sirens:
General alarm signal
A minute-long rising and falling sound, which is repeated at least three times after a 30-second pause.
A general alarm signal is used to draw attention to all hazards, and this means that additional information and behavioral guidance is expected on the hazard!
End of general alarm
Even continuous one-minute length sound transmitted once.
The alarm end signal means that the danger is over.
Even continuous sound with a total length of up to 7 seconds.
The test signal means routine testing of the siren and does not involve compulsory activities for the residents.
How to behave when you hear a siren:
1. When being outdoors, move away from the danger zone perpendicular to the wind direction!
2. Go to the enclosed space to protect yourself from gas or explosion!
3. Close all doors and windows and ventilation ducts properly!
4. In the car close the doors and windows and switch off the ventilation;
5. Inform and help neighbors and other people in the vicinity!
6. Turn on Vikerraadio (see frequencies), Raadio 4 (see frequencies) or ETV and listen for the guidelines provided there! You can also get information at www.rescue.ee and from the Rescue hotline 1247 (24 h).
7. If you sense unusual odors, hold wet towels in front of your mouth and nose and go to the upper floors, as the toxic gases that are heavier than the air accumulate downwards.
8. Do not use naked flames!
9. Use the phone only in serious need, so as not to overload phone lines.
