The U.S. Dept. of Labor’s Occupational Safety and Health Administration has published a new booklet to summarize its standards for workplace exposure to hexavalent chromium.

Hexavalent chromium is a toxic chemical used in pigments, metal finishing, wood preservatives and fungicides. Welders are notably at risk of exposure because hex-chrome fumes are generated during welding of chromium metal alloys. OSHA said that inhaling hex-chrome fumes may cause allergic reactions or asthmatic symptoms, including wheezing and shortness of breath.

Hexavalent Chromium is a companion to OSHA’s 2006 guide, Small Entity Compliance Guide for the Hexavalent Chromium Standards. The new booklet explains the relevant OSHA standards in a reader-friendly format, including the requirements for exposure limits, exposure monitoring and determination, protective work clothing and equipment, medical surveillance, communication of hexavalent chromium hazards and recordkeeping are described.

“Hexavalent chromium is a powerful lung carcinogen and exposure to this chemical must be minimized,” stated Assistant Secretary of Labor for OSHA David Michaels. “OSHA provides guidance on its standards to ensure that employers and workers know the best ways to prevent workplace injuries and illnesses.”
