OSHA issued a
final rule on Feb. 28, 2006, that addresses occupational
exposure to hexavalent chromium [Cr(VI)].
OSHA determined that the rule was necessary to
reduce significant health risks due to Cr(VI) exposure.
Certain Cr(VI) compounds have been found to
cause lung cancer and nasal cancer in humans.
Inhaling relatively high concentrations of Cr(VI) can
also cause a wide range of other health effects (e.g.,
runny nose, sneezing, itching, nosebleeds, ulcers,
holes in the nasal septum). Ingestion of very high
doses of Cr(VI) can cause kidney and liver damage,
nausea, irritation of the gastrointestinal tract, stomach
ulcers, convulsions and death. Dermal exposures
may cause skin ulcers or allergic reactions.
Activities with the potential for Cr(VI) exposure
include:
