This document, which was developed for presentation at a seminar on adult learning and safety, examines approaches to occupational safety and health (OSH) learning/training in the workplace. Section 1 examines selected factors affecting adults' learning in workplace OSH programs. The principal dimensions along which individual adult learners will differ from one another and the different learning processes in which individual adults may engage are listed. Section 2 describes three novel patterns/approaches to OSH learning in the workplace--action learning, situated learning, and incidental learning--and identifies characteristics shared by them. Section 3 presents an overview of thrusts and levels of the following types of OSH learning/training programs: fundamental programs; recognition programs; problem-solving programs; and empowerment programs. Section 4 explores the following critical aspects of OSH learning/training in the workplace: assessing needs; establishing learning/training objectives; specifying learning/training content and media; accounting for individual differences; specifying learning conditions; evaluating training (evaluating trainees' reaction to the training, their knowledge gain, their behavior change, and the training program's tangible results for the organization); and revising the training. The training development model underpinning the United States Occupational Safety and Health Administration's voluntary training guidelines is detailed. Section 5 summarizes key lessons/conclusions of the seminar presentation. The bibliography lists 17 references. (MN)
