Local Exhaust Ventilation Hexavalent Chromium

In February, 2007, OSHA published a new standard drastically reducing accepted exposure to hexavalent chromium in the workplace.

Compliance with the new standard means a reduction in the permissible exposure limit (PEL) to hexavalent chromium fume, or Cr(VI), from 52 micrograms per cubic meter of air averaged over an 8-hour period to five micrograms.


Companies with more than 20 employees had a 2006 deadline for compliance with the new OSHA standard. Companies with fewer than 20 employees must achieve reduction of hexavalent chromium levels to within the PEL by May 31 of 2007

Local Exhaust Ventilation for
Hexavalent Chromium Reduction


In their "Small Entity Compliance Guide for the Hexavalent Chromium Standards" OSHA suggests a preferred compliance approach for reduction of fume as using engineering controls such as local exhaust ventilation:

Ventilation (e.g. local exhaust systems that capture airborne Cr(VI) near its source and remove it from the workplace, or general ventilation that dilutes Cr(VI) concentrations by circulating large quantities of air a local exhaust system is generally preferred to dilution ventilation because it provides a cleaner and healthier work environment.
