A workshop was designed to (1) train teachers to become experts on chemical safety and storage; (2) examine and evaluate chemical storage in 12 Carroll County (Maryland) schools; and (3) develop a safety guide for all county science classrooms. Development, implementation, evaluation, and implications of the workshop are addressed. (JN)

Describes a demonstration involving the controlled combustion of a mixture of metals with black and smokeless powder in a small Erlenmeyer flask. Also describes demonstrations using a device that precludes breathing of hazardous vapors during class demonstrations; the device is easy to transport and use in rooms without sinks. (JN)

Discusses six common problems which may occur when using temporary labels on chemicals, samples, or mixtures in teaching or research laboratories. Solutions to each of these problems are offered. (JN)
