Synthesis of research on safety in agricultural education laboratories found most research focused on agricultural mechanics. Labs appeared to be potentially hazardous places, and teachers have inadequate knowledge of safety laws and ways to provide a safe working environment. (SK)

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…

The feasibility of the laboratory production of copper metal from a readily available, naturally occurring mineral malachite utilizing techniques that are consistent with the time period of around 4000 B.C.E. is presented. The starting materials are inexpensive and convenient and the procedure involves no hazardous reagents and produces no…

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.

Choosing what eye and face protection to provide for the high school science laboratory is often a challenge. Science teachers and school administrators may not fully understand the relevant safety regulations and standards or be able to correctly identify the various types of eye protection devices. Although some schools have received training…

An alternative method for the preparation of Pasteur pipet chromatography columns is presented that allows the column to be filled with solvent without bubbles and allows greater control of fluid flow while the materials to be separated are added. Students are required to wear gloves and goggles and caution should be used while handling glass…

This paper is predicated on the realization that a chemical hood is only one element of laboratory safety which encompasses a variety of other elements starting with the architectural design and layout of laboratories; through the installation, operation and maintenance of integrated electrical and mechanical systems; to the safety-mindedness of…

The three common laboratory accidents, Cuts, Burns, and Fainting are considered from the aspects First Aid treatment and prevention. (Author)

This booklet outlines general safety procedures in the areas of: (1) student supervision; (2) storage safety regulations, including lists of incompatible chemicals, techniques of disposal and storage; (3) fire; and (4) first aid. Specific sections exist for elementary, junior high school, senior high school, in which special procedures are…

Detailed discussions are presented dealing with the selection and design of fume hoods for science laboratories. Areas covered include--(1) air flow design, (2) materials properties, (3) location in the laboratory, (4) testing and adjustment, (5) exhaust systems, and (6) hazards of fume discharges. (JT)

Recommendations are made to ensure that academic laboratories are safe and meet safety standards, instruction and information in laboratory safety are widely available, and that students, teachers, and academic research chemists give high priority to safety and health in their laboratories.
