Household hazardous materials are products or wastes which are toxic, corrosive, reactive, and/or ignitable. Although common products such as pesticides, oils, gasoline, solvents, cleaners, and polishes are hazardous, students and adults are not always aware of potential dangers. This sourcebook contains definitions and examples of household hazardous materials, includes information about pesticide and chemical product labels, and presents classroom projects and worksheets which may be used with a variety of curricula. A discussion of automotive products, household cleaners and polishes, paints and solvents, hobby and art supplies, pesticides and herbicides, personal and health care products, aerosol sprays, and alcohol, tobacco, and plants is included.
