Chemical Emergencies

In a chemical emergency, if you come in contact with a known or unknown chemical, you should get away from the area, get it off your body as soon as you can, and get help by calling the Poison Control Center at 800-222-1222 or calling 911 or going to the nearest hospital. Since chemical emergencies can happen at any time, plan ahead so you are ready to evacuate or stay put and seal off your space.
