A hazardous polymerization is the above reaction with an uncontrolled release of energy. Reactivity A substance's susceptibility to undergoing a chemical reaction or change that may result in dangerous side effects, such as explosion, burning, and corrosive or toxic emissions. Respirator A device which is designed to protect the wearer from inhaling harmful contaminants.
