Keywords: Hexavalent Chromium (8743403525).jpg The photo shows welding in an enclosed chamber to collect welding fumes for analysis and characterization The goal is to identify and improve welding processes that generate as little fume and especially as little hexavalent chromium as possible while maintaining good quality welds Welders have increased incidences of lung cancers and other respiratory diseases and this is an opportunity to apply chemistry and engineering to find ways to minimize workplace hazards Stopping or slowing hazards at the source can be especially useful and make engineering controls and other techniques even more effective https //www flickr com/photos/niosh/8743403525/ Hexavalent Chromium 2011-03-18 13 24 https //www flickr com/people/25069384 N03 National Institute for Occupational Safety and Health NIOSH from USA PD-USGov NIOSH http //flickr com/photos/25069384 N03/8743403525 2015-04-26 21 50 47 United States Government Work Safety Welding Work Workplace National Institute for Occupational Safety and Health |
