The N-methylpyrrolidin-2-one hydrotribromide complex (MPHT) is a stable solid that can be stored several months at room temperature. The MPHT is not corrosive, not necrosing, less toxic and easier to handle for students as compared to the molecular bromine.

Tips that laboratory researchers and beginning graduate students can use to safeguard against explosion hazard with emphasis on clear illustrations of molecular structure are discussed. Those working with hazardous materials must proceed cautiously and may want to consider alternative and synthetic routes.

Discusses the code of the Royal Institute of Chemistry (RIC) in Great Britain concerning laboratory safety; includes sections on hazardous chemicals and techniques, and legal responsibilities. (MLH)

Potential safety hazards in the science classroom are surveyed. Some of the more potentially dangerous materials are described: mercury, formaldehyde, and black light radiation. The biological hazards of diseases carried by animals and of exposure to petri dish cultures are discussed. Five references on safety are included. (DT)

Indicates dangers inherent in the use of polythene or polypropylene sinks and presents alternatives to their use. (GS)

The appreciation of the potential hazard of ionizing radiation led to the setting up of national, and later, international commissions for the defining of standards of protection for the occupationally exposed worker in the use of ionizing radiation. However, in the last twenty years, with the large scale development of nuclear energy, the need…

Discusses the legal requirements for laboratories that create hazardous wastes. Alternatives for waste disposal, including using a licensed disposal company or recycling, are proposed. (CH)

The author discusses Environmental Protection Agency regulations concerning ventilation of industrial plants and school industrial laboratories. Various alternatives are presented. (CH)

Short articles on the alkylation of aniline, the preparation and properties of perbromate, using scrap copper in chemistry instruction, a safe method of burning hydrogen, and the use of an ion-charge model as an alternative to the mole concept in secondary school instruction. (AL)

Describes laboratory inspection forms developed by the New York section of the American Chemical Society and recommends that they be used by qualified college safety officers. Includes instructions on how to order full-size copies of the forms suitable for duplication. (SK)
