On the air contaminants standard recommended that all Cr(VI) compounds, regardless In 1975 NIOSH documented the carcinogenicĮffects of water-insoluble Cr(VI) compounds. Which are practically insoluble in water. erosion and discoloration of the teeth.Ĭr(VI) compounds vary in solubility from those that are readily soluble to those Other adverse health effects associated with Cr(VI) exposure include Risk of lung cancer has been demonstrated in workers exposed to Cr(VI) compounds. Cr(VI) exposuresĪlso occur during other work activities such as stainless steel welding (possiblyĪlso from stainless grinding), thermal cutting, chrome plating, painting, andĬonsiders all Cr(VI) compounds to be potential occupational carcinogens. Of stainless steels, chromate chemicals, and chromate pigments. Occupational exposures to Cr(VI) compounds occur during the production That contain the metallic element chromium in its positive - 6 valence (hexavalent) These compounds are part of a group of chemical substances Primary concern when welding common stainless alloys is "Hexavalent Chromium" Unfortunately its not just industry that will often ignore the dangers, the medical profession is aslo in many instances ignorant to the health hazards from weld fumes. Of course there always has been helath consequences which can come in the short term or over long periods of time. Its a sad statement that many managers will turn a blind eye to the dangers that come from fumes when welding alloys and coated parts. Weld fume danger ignorance has gone on for decades throughout the global weld industry, however the appropriate weld fume research and safety regulations are found in organizations such as OSHA - NIOSH - AWS. Often has stupidity, poor work judgement, lack of management, greed or lack of training been the cause of serious work accidents. This web site was first established in 1997 by Ed Craig.Ĝontact Ed.
