Notice required for all hexavalent chromium exposure tests


When monitoring exposure to hexavalent chromium, employers will have to share all results with affected workers, under a new regulation from the Occupational Safety and Health Administration (OSHA). Previously, OSHA only required notice to employees when their exposure to hexavalent chromium climbed above the federal permissible exposure limit of five micrograms per cubic meter of air. The rule takes effect on June 15, 2010 (75 Fed Reg 12681 (March 17, 2010) and 75 Fed Reg 27188 (May 14, 2010)).

Tips: Welders make up almost half of all employees exposed to hexavalent chromium. Welders can reduce their exposure by adjusting their technique and posture. Portable local exhaust ventilation can also help. Reducing exposure is important, because OSHA estimates that a lifetime of regular exposure to just one microgram of hexavalent chromium per cubic meter of air puts workers at an increased risk of lung cancer.
