Prevention of large-scale accidents (often called organizational disasters) is growing in importance in today's industrial organizations. Organizational disasters where large numbers of people and wide geographic areas are affected can mean serious economic and operation disruption to an organization. The role of managers in the prevention of organizational disasters is described as critical. However, typical manager attitude towards organizational disasters is that occurrence is unlikely. This attitude causes them to neglect prevention strategies and activities. Shaping the attitudes of future managers during their university level training (e.g., in MBA programmes) through a class in ergonomics and safety is described as one means to shape manager attitudes. Psychological models of attitude formation and behaviour show that an attitude is stronger when there is learning about a topic. Greater knowledge and interest may later prevent organization disasters when students become managers. There would likely be an additional benefit of greater awareness of existing ergonomics and safety programmes that guard against small, single worker accidents.
