A major chemical or biological emergency can happen when hazardous
amounts of toxins are released into the environment. You can be exposed
to chemical and biological toxins by:
Swallowing contaminated food, water or medication
Touching or coming into contact with contaminated items
times you cannot see or smell anything unusual. In the event of a
chemical or biological emergency, you will be given instructions by
authorities. You may be told to shelter in place, to move uphill and
upwind of the release, to evacuate or to go to a designated facility.
You may also be in the immediate vicinity of an incident and not realize
the danger. If you see people vomiting, in convulsions or acting
disoriented, leave the area immediately and seek medical attention. If
out of doors, check the wind and walk upwind to evacuate the area.
