The primary concern of the Occupational Safety and Health Act (OSHA) is to provide a safe and healthful workplace for every working man and woman in the nation. One way to help reduce the number of injuries and illnesses in the workplace is by training workers to be more aware of the job safety and health hazards and to teach them the methods of reducing and/or eliminating those hazards. To assist employers in carrying out this function, OSHA has developed several training programs that may be presented at the worksite. OSHA has prepared this guide to aid those non-professional instructors who may be charged with the responsibility of training employees. This booklet offers information on the nature of the occupational safety and health problems, on what is presently known and accepted about the technology of causing learning to take place, and on methods recommended to prepare for a teaching session, as well as on tools and methods for conducting the teaching. Detailed instructions showing how to put the principles to work and get the results expected of the professional teacher are given. (HD)
