Protect Yourself

If you become aware of an unusual and suspicious release of an unknown substance nearby, you can take measures to protect yourself. Quickly get away. Cover your mouth and nose with layers of fabric that can filter the air but still allow breathing. Examples include two to three layers of cotton such as a T-shirt, handkerchief or towel. Otherwise, several layers of tissue or paper towels may help. Wash with soap and water and contact authorities.
