The consequences of broken mercury-in-glass thermometers in academic laboratories results in various health and environmental hazards, which needs to be replaced, by long-stem digital thermometers and non-mercury glass thermometers. The factors that should be considered during the mercury replacement process are types of applications in the…

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…

A chemical laboratory information profile (CLIP) is presented for the chemical, stearic acid. The profile lists the chemical's physical and harmful characteristics, exposure limits, and symptoms of major exposure, for the benefit of teachers and students, who use the chemical in the laboratory.

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.

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.

Planning and prevention is the best defense against fires in school. This is particularly true in the science laboratory due to the presence of flammable gases, liquids, combustibles, and other potential sources of fire. Teachers can prevent fires from starting by maintaining prudent lab practices when dealing with combustible and flammable…

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.

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…

Mercury tends to vaporize when exposed to air. The warmer the air, the more quickly it vaporizes. Although swallowing mercury can be a problem, the greater risk results from inhalation and skin absorption. Symptoms and health-related problems can result within hours of exposure. Spilled mercury settles in cracks and absorbent material such as…

A chemical laboratory information profile (CLIP) is presented for the chemical, triethanolamine. It summarizes the chemical's physical and harmful features, exposure limits, and symptoms of major exposure for the benefit of teachers and students, who use the chemical in the laboratory.

Children and adolescents, up to approximately age 20, are more susceptible than adults to potential health risks from chemicals and environmental hazards. Hazardous chemicals can interrupt or alter the normal development of a child's body, leading to lasting damage. Since children are smaller than adults, similar levels of exposure to toxic…

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…

Explains that mercury is a dangerous substance to use in school science laboratories and gives several examples of mercury poisoning. Lists some precautions that should be taken in case of mercury spillage in the lab. Advocates using non-mercury laboratory equipment and limiting student access to mercury to prevent dangerous situations. (YDS)
