CHROMIUM TRIOXIDE CHROMIC ACID
Chromic Acid (Dichromic Acid, Chromium Trioxide) is most known for its use in the metal finishing (intermediate in chromium plating) industry. Other common uses are as a wood preservative, production of plastic products, ceramic glazes and to clean laboratory glassware
The major uses of chromic acid are in wood preservation, metal finishing and plating. Secondary applications
include catalyst manufacture and as an oxidizing agent.
Chromic acid is used to produce salt-free CCA type wood preservatives. These preservatives are
combinations of chromium, copper and arsenic. The CCA offers protection from wood destroying fungi, marine borers, termites, ascomycetes, white rot, dry rot and brown rot.

standard applies to all occupational exposures to any chromium species with a valence of positive six, regardless of form or compound, including chromates and chromic acid. OSHA has established a ceiling value of 1 mg/10m³ for any operations or sectors where the exposure limits in §1910.1026 are stayed or otherwise not in effect
