Attitudes and Incident Causal Modeling for Construction Principal investigator(s): Brenda McCabe (University of Toronto) Co-investigator(s): Douglas Hyatt, Catherine Loughlin (University of Toronto); Susan Tighe (University of Waterloo) Sponsoring Institution: University of Toronto Objective The objectives of this study were: to document attitudes toward safety and safety incidents on construction sites to collect detailed information about events and conditions leading to injury and non-injury incidents to develop a probabilistic model of workplace safety. Method Data collection was achieved with 911 self-administered questionnaires. Non-parametric statistical analysis methods were used as most variables were not normally distributed. Results Ninety percent of the workers surveyed had at least one incident in the previous three months. Workers with more physical symptoms were younger, had greater mobility, increased work pressure, lower perception of job safety, and less job involvement. Workers with psychological symptoms had more interpersonal conflict. Role overload and psychological symptoms were highest among supervisors. Those who experienced an accident in the previous three months felt more work pressure and had less confidence in the safety of their work. Conclusions This study suggests that mobility plays a more significant role in safety performance than the nature of the work. The industry may consider establishing common safety and prevention programs for contractors. Consistent safety cultures across firms may provide the same benefits as long-term employment with one firm. In the union sector, this might be accomplished through stronger partnering between unions and employers. For more information: mccabeb@civ.utoronto.ca
