SCHOOL CHEMISTRY LABORATORY SAFETY GUIDE


Recognition of laboratory safety and health problems has crystallized since the passage of the Occupational Safety and Health Act of 1970. This Act requires that certain precautions be observed to protect the safety and health of employees on the job. The employee designation includes all teachers employed by private and public school systems in States that have occupational safety and health plans accepted by the Occupational Safety and Health Administration (OSHA) of the U.S. Department of Labor (DOL). OSHA rules and regulations are provided to protect the employees and the facilities.

The importance of laboratory safety has been recognized for many years in industry. However, educational institutions have been slower to adopt such safety practices and programs. A science program has certain potential dangers. Yet, with careful planning, most dangers can be avoided in an activity-oriented science program. It is essential for all involved in the science instruction program to develop a positive approach to a safe and healthful environment in the laboratory. Safety and the enforcement of safety regulations and laws in the science classroom and laboratory are the responsibility of the principal, teacher, and student—each assuming his/her share. Safety and health should be an integral part of the planning, preparation, and implementation of any science program.

The Importance of Safety
Safety and health considerations are as important as any other materials taught in high school science curricula. Occupational injury data from industry studies indicate that the injury rate is highest during the initial period of employment and decreases with experience. Similarly, in a high school laboratory setting where students experience new activities, the likelihood of incidents, injury, and damage is high. Therefore, it is essential that the students are taught what can go wrong, how to prevent such events from occurring, and what to do in case of an emergency.
Teacher’s / Instructor’s Viewpoint
Teachers have an obligation to instruct their students in the basic safety practices required in science laboratories. They also have an obligation to instruct them in the basic principles of health hazards that are found in most middle and secondary school science laboratories. Instructors must provide safety information and training to the students for every stage of experiment planning and be there to observe, supervise, instruct, and correct during the experimentation. Teachers play the most important role in insuring a safe and healthful learning environ ment for the students. The ideal time to impress on students’ minds the need for caution and preparation is before and while they are working with chemicals in science laboratories.
Student’s Viewpoint
Students develop attitudes towards safety and acquire habits of assessing hazards and risks when they are young. Students come from diverse backgrounds and have various levels of preparation. Most of them have no previous hands on training in handling chemicals or equipment; others may come well prepared to assume personal responsibility for risk assessment and safety planning in their experiments. The school science laboratory provides an opportunity to instill good attitudes and habits by allowing students to observe and select appropriate practices and perform laboratory operations safely. Safety and health training lays the foundation for acquiring these skills. The students should think through implications and risks of experiments that they observe or conduct in order to learn that safe procedures are part of the way science must be done.
Student motivation in any area of education is a critical factor in the learning process. Emphasizing the importance of safety and health considerations by devoting substantial class time to these areas should help. The current popular preoccupation with matters of industrial safety and health may also serve as motivation. Students may fnd a discussion of toxicology interesting, informative, and benefcial. The possibilities for working this material into the science curriculum are innumerable and limited only by the imagination of the teacher.
School’s Viewpoint
Support for laboratory safety programs is the responsibility of school system administrators. School system administrators should appreciate the need for establishing safety and health instruction as a fundamental part of a science curriculum and should operate their schools in as safe a manner as possible. No Federal law requires safety and health programs to protect students in schools.
The Occupational Safety and Health Act of 1970 requires employers to provide safety and health protection for teachers and other school system employees. Some States (North Carolina, for example) require school systems to abide by State regulations, which are similar to the OSHA Laboratory Standard (29 CFR 1910.1450). All safety programs must actively involve the school administrators, supervisors, teachers, and students, and all have the responsibility for safety and health of every other person in the laboratory and school.
