Determined that an instructional unit on laboratory safety could increase student safety knowledge and reduce the number of unsafe behaviors. A list of unsafe behaviors which were observed with the 333 students is included. A recommendation that positive attitudes toward safety be developed is given. (DH)

Highlights aspects of safety that are unfamiliar to most laypersons and to many chemists as well. Presents findings that may lend themselves to presentation in chemistry classes. Details flammability tests, vapor space hazards, and the special case of gasoline containers. Provides experimental data relating vent area and internal pressure. (CW)

Provided is an empirical method to train students to avoid physical disaster in their work experience. Discussed is a computer program, CHETAH, which can be used in advance of synthesis to classify the possible explosive nature of the products. Plosophoric and auxoplosive weights of many organic groups are listed. (MVL)
