Interrelationships among highly effective construction injury prevention strategies

Preventing injuries to workers is essential to effective organizational management in the construction industry. It is generally accepted that achieving a high level of safety performance requires the implementation of an effective safety program. In an effort to provide guidance for the development of an effective safety program, previous studies have focused on identifying highly effective injury prevention strategies and quantifying their individual impacts on safety performance. Despite these advancements in knowledge, the synergistic interrelationships among highly effective injury prevention strategies remain unknown. The objective of this paper is to describe the results of a Delphi study that quantified the interrelationships (i.e., pairwise cross impacts) of highly effective and commonly implemented injury prevention strategies. Analysis of the data indicates that the site safety manager, worker participation and involvement, a site-specific safety plan, and upper management support and commitment are the most central elements in an effective program. It is expected that the results of this study can be used by practicing professionals when designing a new safety program, enhancing an existing program, or conducting economic analyses of safety-related investments.
