A survey and hearing test of 46 male agriculture teachers in West Virginia had the following results: (1) 36 had some high- frequency hearing loss; (2) 66% did not receive information on hearing in college; (3) 35% never wear hearing protection; (4) 51% have trouble getting students to use safety equipment; and (5) only 9% have had the sound…

Presents a creative set-up that allows students with latex allergies full participation in chemistry labs. Discusses how one student having a latex allergy is turned into a learning experience for all and how this challenged lab safety. (ASK)

Addresses bloodborne pathogen hazards in the laboratory. Provides specific recommendations for preventative measures and information about legal issues involved. (MM)

As heat sources go, the old standby for elementary and middle school science laboratories has been the centuries old alcohol lamp. Unfortunately, this inexpensive heat producer has been a continuous source of accidents--many of which are relatively serious. Hot plates are emerging as the most popular source of heat for science experiments. The…

The disposal of hazardous chemicals and chemical containing products is of much concern and there is a need for a document that describes the hazards of a chemical, to consider the precautionary measures to be taken. Many classic demonstrations however cannot be performed due to safety concerns since sometimes chemicals are deemed too hazardous or…

The widely used method of synthesizing HCl and DCl gases for infrared analysis by hydrolysis of benzoyl chloride includes a potentially dangerous final step whereby the frozen product is allowed to heat and expand into an infrared gas cell. The subsequent rapid rise in vapor pressure can "pop" open glass joints in the vacuum line and vent the…

A successful microscale fusion of semicarbazones, or transformation of carbonyl compounds into semicarbazones is performed through an effective grinding system. The donning of protective attire is advised to avoid the hazardous effects of semicarbazide hydrochloride during the fusion process.

The hazards of silver used in the laboratories are described for the benefit of the students and the teachers. The exposure limits and symptoms due to acute exposures are also mentioned.

The hazards caused by calcium used in the laboratories are described. The exposure limits and symptoms of acute exposures are mentioned.

The guide presents information about ordering, using, storing, and maintaining chemicals in the high school laboratory. The guide also provides information about chemical waste, safety and emergency equipment, assessing chemical hazards, common safety symbols and signs, and fundamental resources relating to chemical safety, such as Material…

A primary goal of the American Chemical Society Task Force on Laboratory Waste Management is to provide laboratories with the information necessary to develop effective strategies and training programs for managing laboratory wastes. This book is intended to present a fresh look at waste management from the laboratory perspective, considering both…

Quotes several sections of the Health and Safety at Work etc. Act 1974, and discusses how these sections will affect science teaching at all levels in Great Britain. (MLH)

The occupational safety and health standards adopted for fourteen carcinogens are specified and discussed. Standards on benzidine and beta - propiolactone are reprinted in full as examples. (DT)
