Several recent reviews of industrial accidents have given increased attention to the role of organizational factors as antecedents to the accident sequence. In the current study, three group-level factors (i.e., group process, safety climate, and intentions to approach other team members engaged in unsafe acts) and one individual-level factor (i.e., perceptions of role overload) were hypothesized to influence the frequency of reported unsafe behaviors using a cross-level research strategy. Data were collected from 21 teams and 222 individuals in a Midwestern chemical processing plant. Both the individual and group-level variables were significantly associated with unsafe behaviors, thereby supporting the cross-level hypotheses. There was also initial evidence suggesting that the group process-unsafe behavior relationship was mediated by intentions to approach other team members engaged in unsafe acts. At the team level of analysis, safety climate and unsafe behaviors were significantly associated with actual accidents. Group process and approach intentions were marginally related to actual accidents (p < .10). The implications for a cross-level approach to safety and interventions is discussed.
