The five parts are: definition of a hazardous material; criteria for determination of degree of hazard; preparation of a MSDS; preparation of a hazard alert symbol; and selection of label statements. Relative toxicity rating and acute toxicity criteria are given for materials with different degrees of hazard. Ratings are also given for the flammability and reactivity of materials.
