Reports on the use of a technique that involves students in researching the hazardous properties of chemicals they are about to use. Students include this information in their lab reports focusing on product and company identification and hazards identification. (DDR)

Explores the after-effects on college laboratories of the anthrax mail scare; scientists say the anthrax scare justifies tougher rules on biological agents, but some fear that Congress may go too far. (EV)

Lab safety is a critical component of any science class, but it is certainly not the most popular. This is especially true for younger students who are new to lab-based science classes. Educators must teach them about the dangers of unsafe lab behavior without scaring them away from the lab entirely or boring them to the point that they don't…

Discusses the relative instability of organic oxidants, citing early attempts at overcoming the solubility limitations in organic reaction systems. Describes the more recent introduction of new types of organic oxidant salts that have demonstrated more promising levels of stability, though unexpected explosions have still occurred. (TW)

Discusses institutional biosafety committees (IBC) which provide quasi-independent reviews of recombinant DNA work done at an institution. Considers the nature of IBC operation, the National Institutes of Health "Guidelines for Recombinant DNA Research," the composition of IBCs, the intellectual content of IBC deliberations, and issues…

Presents a sample contract for disposing of hazardous wastes in an environmentally sound, timely manner in accordance with all federal, state, and local requirements. Addresses situations where hazardous waste must be disposed of outside the laboratory and where alternate disposal methods are not feasible. (JN)

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

Proposes use of two experiments to sample and analyze contaminents in the laboratory. Experiments focus on estimating hydrogen sulfide levels in the general chemistry laboratory during qualitative analysis and determining the concentration of organic vapors associated with organic chemistry laboratories. (JN)

Describes a course designed to provide secondary school science teachers with the background necessary to implement an effective safety program for their science labs. Lectures, demonstrations, group discussions, slides, films, videotapes, and guest speakers were utilized in the two-credit hour, summer course. Evaluations indicated course…

The Consumer Product Safety Commission will recommend an information network to inform students and teachers of current toxicity evaluations of chemicals and of possible use of less hazardous substitutes. Lists names of 33 suspected carcinogens and 11 suspected teratogens. (SK)

Recommends that science teachers make evaluations of chemical atmospheres in science laboratories so that serious health problems can be avoided. Uses data from methylene chloride to provide guidelines for understanding the effects of chemicals on the human body. (CS)

Reports methods for identifying carcinogens and suspected carcinogens in the undergraduate laboratory and makes recommendations for their elimination or control. (CS)

Provides specific procedures for the disposal of a variety of highly reactive chemicals and reports the results of a study of their safe disposal. Disposal of some problematic sulfur-containing compounds are included. Procedures are based on a combination of literature review and author development. (LZ)

As a first step towards the greening of instructional laboratories, we present a new greener version of a laboratory procedure designed to measure colligative properties. The greener procedure substitutes the nontoxic, noncarcinogenic compounds stearic, myristic, lauric, and palmitic acids for the less benign aromatic compounds p-dichlorobenzene,…

A novel instrumental-digestion technique using pressure-assisted chelating extraction (PACE), for undergraduate laboratory is reported. This procedure is used for exposing students to safe sample-preparation techniques, for correlating wet-chemical methods with modern instrumental analysis and comparing the performance of PACE with conventional…
