Updating Hexavalent Chromium Detection Capabilities
An industry safety expert suggests testing methods to detect hexavalent chromium needs to adapt to ever changing industrial environments to provide shorter time-sample results.
An industry safety expert suggests testing methods to detect hexavalent chromium needs to adapt to ever changing industrial environments to provide shorter time-sample results, such as 5- or 10-minute increments and with accuracy near laboratory testing.
Alex Mazzotta, a mechanical engineer at Figure Engineering based in Lorton, Virginia, writes in an article that appears in the September 2019 issue of Occupational Health and Safety that such capability will significantly enhance visibility on exposure, but he says what’s even more impactful is the ability to determine potentially unknown sources of dust or fumes that expose unprotected personnel.
Mazzotta writes, “at the United States Air Force depot at Hill Air Force Base, there was an issue just like this. Within a large building where abrasive blasting takes place in a large walk-in blast booth, OSHA found Cr(VI) exposure to be far in excess of mandated PELs. This shed light on a series of unidentified sources in the building that were generating Cr(VI) fumes and dust.”
