| 摘要： | The Navy and the National Shipbuilding Research Program Welding Panel (SP-7) are concerned with the recent and anticipated future reductions in Occupational Safety and Health Administration (OSHA) and American Conference of Governmental Industrial Hygienists (ACGIH) worker exposure limits for airborne emissions. these changes involve nickel (Ni), manpanese (Mn), and hexavalent chromium (Cr(Vl)) . The concerns are due to the potential impact these reductions may have on operations in Navy facilities, public Shipyards, and private shipyards involved in the construction, maintenance, and repair of ships. A Navy/Industry task Group lead by the Naval Sea Systems Command prepared this report of the technical and economic impact of these new and anticipated reductions in worker exposure limits. This report: Identifies the manufacturing and repair operations, materials, and processes that are expected to be impacted by the recent and anticipated reductions in exposure limits. Presents data on current Worker exposure levels to Ni, Mn, total Cr, and Cr(Vl). Identifies the technical and economic impact of the anticipated reductions in the Cr(VI) PEL on Navy facilities and public and private shipyards. Identifies future actions that may be required to comply with the recent and anticipated reductions in exposure limits. This study concludes that workers in Navy facilities and public and private shipyards who perform the following operations have the potential for exposure to Ni, Mn, total Cr, and Cr(Vl) : Construction, Structural Fabrication and Repair of Facilities; Metal Cleaning; Casting; Plating; Painting; Coating; Machining; Welding; thermal Spraying; thermal Cutting and Grouping Woodworking (of pressure treated Wood); and Services (includes Transportation, motor vehicle, maintenance). |
