Describes safety education curriculum units produced by the Science Teacher Education Project (STEP) in Great Britain. (MLH)

Outlines safe laboratory procedures for the handling of micro-organisms including aseptic technique, manipulation of cultures, and treatment of contaminated equipment. Identifies the principal hazard as the microbial aerosol, explains its possible effects, and describes the appropriate precautions. (GS)

Describes a method for the preparation of hydrogen gas which is safer than conventional procedures. The procedure and equipment are described in detail. (BR)

Provides information on updating older fume hoods. Areas addressed include: (1) adjustment of the hood's back baffle; (2) hood air leakage; (3) light level; (4) hood location in relation to room traffic and room air; and (5) establishing and maintaining hood performance. (JN)

Highlights guidelines that should be implemented in administering a plan for the proper storage of chemicals. They include housing chemicals in multiple locations within a building to lessen the accident potential, not grouping them in alphabetical order, and storing them according to six major chemical classes. (JN)

Experimental data, Federal and State regulations, and user data are presented to assess the safety factors of low-power lasers. General safety precautions, basic laser theory, the place of the laser in the classroom, and some introductory exercises are also presented. (Author/TS)

Results from two surveys of chemists and educators conducted at two conventions indicate weak spots in facilities, poor storage information, and failure to take precautions against reactive hazards. Includes suggestions and a checklist related to a wide range of storage problems. (SK)

Lists 37 chemicals classified as suspected carcinogens and suspected teratogens (chemicals capable of producing malformations in an embryo). Offers suggestions to high school chemistry teachers for conducting safe laboratory investigations by avoiding use of these potentially toxic materials. (Author/JN)

Discusses several accidents which occurred during secondary school science/chemistry laboratory experiments, offering suggestions for conducting safe experiments. Indicates that all experiments should be planned using the safest chemicals and safest reactions illustrating a concept, and that audiovisual aids should be used if no safe experiment is…

Reviews the dangers of benzene as a toxin as well as a flammable substance. (CS)

Suggests that Experiment 13.2 (c) of the Nuffield 0-Level Chemistry Course be banned since the oxidation of lithium under very humid conditions can cause an explosion. (LS)
