Leap of Faith Technologies was funded by NIH to develop a tool that would provide organizations with a way to manage HAZCOM data and administer safety training. We wanted to answer two questions: • Could an Internet-based tool be developed to do this? • Were there existing theoretical models that could be applied to study the tool’s use in occupational health? The resulting product, called @ware, was developed as an Internet-based program for hazard communication and safety training. Its development was based on the Theory of Planned Behavior, which suggests that an individual’s attitudes, subjective norms, and perceived behavioral control determine an individual’s intention to engage in a specific behavior. We hypothesized that the program could have a positive effect on attitudes, norms, and perceived behavioral control because it was self-paced, interactive, provided feedback, allowed flexible scheduling, and was supported by management. Results showed that subjective norms and perceived behavioral control are strong determinants for intentions to use safety procedures and equipment. Feedback from important others is also a reliable measure of behavioral intention. The key source of safety information is formal training.
