What are some common hazardous chemicals?

Some common hazardous chemicals include ricin, perchloric acid and tetranitromethane. Ricin is a poison derived from castor beans and is a waste product left over from the production of castor oil. It causes injury if it is inhaled.

Perchloric acid is a chemical used to make rocket fuel and perchlorate salts. It is a clear, oily liquid at room temperature. It is also a very strong acid and reacts with metals, plastics and wood.

Like ricin, tetranitromethane is dangerous to breathe in, ingest, or get on the skin or in the eyes. Exposure causes burns, shortness of breath and irritation of mucous membranes.
