If you hear a siren or other warning signal, turn on a radio or television for further emergency information. You will be notified of a major chemical emergency by the authorities. To get your attention, a siren could sound, you may be called by telephone, or emergency personnel may drive by and give instructions over a loudspeaker. Officials might even come to your door.
Listen carefully to the radio or television. The Emergency Alert System (EAS), which has replaced the Emergency Broadcast System, may be activated. You will be given specific instructions for your particular situation.
Strictly follow instructions. Your life could depend on it.
You will be told the following:
The type of health hazard.
The area affected.
How to protect yourself.
Evacuation routes (if necessary).
Type and location of medical facilities.
The phone numbers to call if you need extra help.
Call EMS, 911, or the operator only for a possible life-threatening emergency. Telephone lines are frequently overwhelmed in disaster situations. They need to be clear for emergency calls to get through.
