NIOSH Lake Lynn Laboratory

The Lake Lynn Laboratory, an experimental hard-rock mine operated by the NIOSH Pittsburgh Research Laboratory, served as a resource in conducting the "Evaluating Roadway Construction Work Zone Interventions" project, which is evaluating interventions that are intended to prevent ground workers from being struck by construction equipment. In defining the data collection methods for this project, it was necessary to develop blind area diagrams of road construction equipment. These diagrams were used to describe areas around equipment that are hazardous to ground workers. The Lake Lynn facility was utilized in developing diagrams for six pieces of equipment.
