Presents a scenario related to the disposal of potentially dangerous ether. Several suggestions for dealing with peroxide-forming compounds are included. (JN)

An accident prevention/safety check list for chemistry laboratories is printed. Included are checks of equipment, facilities, storage and handling of chemicals, laboratory procedures, instruction procedures, and items to be excluded from chemical laboratories. (SL)

Provides a listing of all state guidelines and regulations pertaining to use of hypodermic syringes, eye safety, and animal care in biology and general science laboratories. (SL)

Presents a model, ChemSafe, that was developed to address and solve the allied problems of chemical purchase, storage, use, and disposal in schools. (ZWH)

Describes some of the dangers involved in working with gas discharge tubes in the laboratory. (ZWH)

Provides a brief description of the physiology of the human ear. The effect of sustained noise levels on hearing loss is discussed, as well as the establishment of maximum noise levels for American industries. (CP)

Offers suggestions and outlines ten easy steps for assuring a safer science classroom environment. Includes such recommendations as: scheduling a safety inspection; displaying safety posters; enforcing a laboratory dress code; establishing a safety reference library; and updating safety report forms and procedures. (ML)

Presents two scenarios to illustrate the difference between liability and negligence. Also presents highlights of four actual cases related to laboratory security, appropriate facilities, proper instructions, and protective gear. (JN)

Provides safety considerations related to chemistry experiments and demonstrations. Includes procedures for a volcano demonstration (which does not use ammonium dichromate) and three clock reactions, a list of hazardous chemicals, and a list of questions to help decide whether the risk of an experiment is acceptable for a class. (JN)

A method of disposal is suggested that is superior to the dilution method. The proceudres are based on the conversion of the wastes to less toxic or harmless forms or neutralization, so that they won't be a shock to the sewage system, and then excess dilution. (Author/DF)

Provides tips for stimulating interest in high school chemistry while imprinting safe laboratory practice. Suggests safe alternatives to potentially dangerous "magic show" and other chemical reactions. Also suggests that safety education be a prerequisite for certification of secondary school chemistry teachers. (Author/JN)

Using microbiology activities in the classroom is an effective way for teachers to address National Standards in the life sciences. However, common microbiology activities that involve swabbing doorknobs and hands are too risky due to the likelihood of culturing human pathogens. In addition, making sterile media and maintaining sterile conditions…

Presents a checklist developed to help chemistry teachers assess conditions in the storeroom. The checklist format facilitates a systematic assessment of storage conditions and serves as a record of where improvements are needed. Also lists classes of chemicals requiring special storage precautions. (Author/SK)

Discusses teacher liability in the science laboratory. Cites specific court cases to illustrate points. (MA)

A rebuttle to the NSTA publication, "Safety in the Classroom" is given. Opinions of the author are substantiated by research and the references are included. (SA)
