The University of Massachusetts at Lowell Work Environment Department, working jointly with four New England coalitions on occupational safety and health (COSH) groups, has developed and is delivering participatory and learner-centered health and safety training for hazardous waste site workers and emergency responders throughout New England. This consortium has created a technical curriculum for hazardous waste workers accessible to the nonspecialist and which, more importantly, draws upon workers' own experience and knowledge as a source of information, education, and experiential resources. In this article, we examine the goals of the consortium, the applicability of the training method, its successes and failures, and the wider implications such pedagogical techniques have for effective and empowering health and safety training. We conclude that such a teaching technique is a successful means of providing technical knowledge and skills in a positive and rewarding atmosphere. We also conclude, however, that the extent to which this form of education is empowering, as is claimed by many of its proponents, is less clear-cut.
