Nitric acid incidents: How to reduce your risk

The hazards: Nitric acid is a highly corrosive mineral acid and strong oxidizer used primarily for nitration of organic molecules and washing glassware or metal equipment. Nitric acid reacts violently with alcohols, alkalis, reducing agents, combustible materials, organic materials, metals, acids, cyanides, terpenes, charcoal, and acetone. It produces exothermic reactions, as well as toxic, corrosive, and flammable vapors.
