On November 17, 2000, the National Institute for Occupational Safety and Health (NIOSH) received a management request from City of Cincinnati Sewers, Water Works & Public Services (CSWP) to evaluate vibration exposure of employees on various pieces of equipment, review work procedures and practices, and offer suggestions for reducing risk from vibration exposure. In response to the request, NIOSH investigators conducted field vibration exposure measurements on the power hand tools used by CSWP employees. Measurements of employees' vibration exposure were obtained while work crews affected repairs or during simulations at the city's storage garage. Unweighted acceleration data in a tri-axial configuration were collected from a representative sample of tools that are used by the city's crews. These data were analyzed and compared to evaluation criteria used in the United States to quantify the levels of vibration exposure for CSWP employees. Many of the evaluated tools generate high levels of vibration that would require limits on the amount of time workers can safely use them. Some of the most severe levels of vibration were measured on jackhammers, paving breakers, and chipping hammers, tools that are used most often by the workers. Recommendations to reduce the vibration exposures are presented in the report.
