Gases (and no, not the kind that you laughed at when you were 8), liquids and/or solids are Chemical warfare agents that can poison people, animals and plants. Chemical warfare agents can cause injuries and death. How serious the injuries are depends on the type of chemical, the amount and the length of exposure.

If a chemical agent attack happens, authorities will instruct people to either seek shelter where they are and seal the premises (shelter-in-place), or evacuate immediately. If ordered to remain in your home, office or school, follow these directions to "shelter-in-place."
