2024年9月6日 · Riot control agents (also called "tear gas") are chemical compounds that cause irritation to the eyes, mouth, throat, lungs, and skin. Signs and symptoms depend on how much you were exposed to, how you were exposed, and for how long. If you were exposed, get clean and get medical care.

Tear gas works by irritating mucous membranes in the eyes, nose, mouth and lungs. It causes crying, coughing, difficulty breathing, pain in the eyes, and temporary blindness.
