This publication is intended to be a resource for teachers and administrators who are responsible for the safety of students, and others, in the general areas where science instructing is occurring. The handbook is designed to assist teachers of science regardless of their background in science. Particular concerns such as laboratory safety procedures, chemical disposal, poisonous plants, and the use of radioactive sources in the classroom are among topics discussed. A bibliography lists additional reference material on science safety available in journals and from state and federal education agencies. (Author/CP)
