This paper documents an approach to meeting the training requirements of the Occupational Safety and Health Act (OSHA) and the "reasonable accommodation" requirements of the Americans with Disabilities Act (ADA) for individuals with developmental disabilities. It describes a training program used with three adult workers with mild mental retardation which utilized icons to teach recognition of: (1) protective equipment; (2) hazards; (3) emergency response equipment; (4) the National Fire Protection Association labeling system; (5) target organs (dangers with acute or chronic effects on specific body organs); and (6) routes of entry (such as ingestation or inhalation). Subjects were given four weekly training sessions. Significant differences were found between baseline and post training scores with substantial maintenance on retesting 2 months after the training. Results have implications for training which increases employment opportunities for people with developmental disabilities. (Contains 14 references.) (DB)
