The National Institute for Occupational Safety and Health (NIOSH) conducts construction-relevant research activities. From 1996 through 2005, the program focused on four research goals: reducing traumatic injuries and fatalities; reducing exposure to health hazards; reducing major risks associated with musculoskeletal disorders; increasing the understanding of construction industry attributes and factors for improving health and safety outcomes. In this book, the National Research Council evaluates the relevance and impact of the NIOSH Construction Research Program in terms of its research priorities and its connection to improvements in the protection of workers in the workplace. It also assesses the program's identification and targeting of new research areas, to identify emerging research issues, and to provide advice on ways that the program might be strengthened. The book finds that the efforts of the Construction Research Program have made meaningful contributions to improving construction worker safety and health, and provides overreaching and specific recommendations for continuing progress. While NIOSH cannot set and enforce research-based standards on its own, the program can be expected to help reduce construction workplace fatalities, injuries, and illnesses through its research, its research dissemination, and transfer into practice.
