A review of the fundamentals of hazardous chemical safety with specific emphasis on flammable liquids, corrosive chemicals, insidious hazards, compressed gases, and cryogenic liquids. (Author/BB)

Provides background leading to a reorganization of the environmental health and safety program at the University of Florida; describes the reorganized program, and discusses experiences from the first year of operation. (MLH)

Explains the benefits and strengths of having safety checklists in science laboratories. Presents a checklist that reflects important components of safety that address many situations in school laboratories. (NB)

Reports the results of a National Science Teachers Association (NSTA) study that analyzed science classroom safety. Examines the potential need for a national safety indexing system to rank states with regard to science safety. (DDR)

Discusses the importance of involving students in assessing the risks versus the benefits of specific laboratory activities, completing accident/incident reports, and performing periodic safety inspections. Concludes that involving students enhances their awareness of both hazards and precautions that must be taken. Provides them another avenue…

Presents a checklist as a guide for preparing a set of safety rules that has been adapted from the U.S. Consumer Products Safety Commission's publication titled "School Science Laboratories: A Guide to Some Hazardous Substances". Addresses work habits; safety wear; facilities and equipment; purchasing, use, and disposal of chemicals; and…

Hearing loss resulting from excessive noise levels remains a concern in technology education laboratories. Teachers must take responsibility to provide a safer, less noisy environment. (SK)

Describes a safety program for teaching science. In the summer of 1999, specific Wisconsin safety laws, codes, and standards were researched and a training program including content, training sites, and dates was developed. One-day training programs were planned for six regions throughout the state. (SAH)

Explains the reasons for allergies to latex gloves and includes suggestions for individuals at risk. (YDS)

Reports on a research project to determine if students possess and comprehend basic safety knowledge. Shows a significant increase in the amount of safety knowledge gained when students are exposed to various topics in laboratory safety and are held accountable for learning the information as required in a laboratory safety course. (Author/MM)

Gases present something of a paradox for the casual observer--they are everywhere and yet, it remains difficult to see them anywhere. The instructional sequence described in this article is an approach that the authors use with middle school students to help enhance their conceptual understanding of gases. Research has shown that these ideas can…

A chemical laboratory information profile (CLIP) of the chemical, aluminum sulfate 18 hydrate, is presented. The profile lists physical and harmful properties, exposure limits, reactivity risks, and symptoms of major exposure for the benefit of teachers and students using the chemical in the laboratory.

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.

Laboratory investigations are essential for the effective teaching and learning of science. A school laboratory investigation ("lab") is an experience in the laboratory, classroom, or the field that provides students with opportunities to interact directly with natural phenomena or with data collected by others using tools, materials, data…
