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.
