A road construction 'flagger' is a construction crew member whose responsibility it is to safely co-ordinate vehicle traffic through road worksites. Flaggers are suffering injuries and fatalities at the worksite as a result of being struck by moving vehicles, both construction and commuter. These incidents are largely preventable with a more defensive flagger training programme. A cross-Canada provincial survey of occupational health and safety organizations revealed no national co-ordination and standardization in flagperson training. Statistics concerning flagger injury and fatality are disjointed and incomplete, and as such are not useful for evaluating and validating training and job performance. We recommend a revisiting of flagperson training standards and that greater effort is taken in gathering data specifically on flagger injuries and fatalities.
