Discussed are accidents that occur in the laboratories of highly trained chemists. Four examples are provided to illustrate potential hazards that are often overlooked in chemistry laboratories, molten inorganic salt baths, the reaction of acetone and hydrogen peroxide, halogenated acetylene compounds, and the reaction of hydrogen peroxide and…

Presented is an experiment in which students recover almost 90 percent of the original lead chloride thus saving on costs of chemicals and disposal. Included are experimental procedures and a discussion of typical results. (CW)

Findings from a survey of 20 liberal arts colleges which did not have graduate programs in chemistry are presented. Discussed are regulations, actions taken and costs of academic laboratories regarding the disposal of hazardous waste. (CW)

Chromium(VI) compounds are classified as oxidizers and must be specially packaged and transported for disposal while Cr(III) compounds are considered nonoxidizers. A process which reduces Cr(VI) to Cr(III) by adding sodium metabisulfite followed by neutralization with magnesium hydroxide is explored. (MVL)

Discussed are the potential hazards associated with nitric acid, inorganic and organic nitrate salts, alkyl nitrates, acyl nitrates, aliphatic nitro compounds, aromatic nitro compounds, and nitration reactions. (CW)

Reviewed is the discovery, nuclear and chemical properties, and uses of an isotope of Americium (Am-241). Production and separation techniques used in industry are emphasized. Processes are illustrated in flow sheets. (CW)
