This manual was intended to provide high school science teachers with a compact reference to hazards encountered while performing experiments in the areas of chemistry, the earth sciences, biology, and physics. A health and safety hazard code was used so that the teacher can at a glance determine the relative danger of a given experiment. Two of the chapters provide an abbreviated course in toxicology and selected safety topics that will be of value to teachers who do not have a background in those areas. Hard to find health and safety information was also included. Teachers were urged to locate the relevant experimental class using the table of contents when preparing experiments. By reviewing these sections the sources of hazards in the experiments can be identified. The work plan then developed should include appropriate corrective and protective action. Potential hazards should be discussed with the students and a professional atmosphere established for conducting the experiments.
