Chromic Acid is a naturally occurring oxide with a formula H 2 CrO 4.. Chromic Acid is also called Tetraoxochromic acid or Chromic(VI) acid. May cause heritable genetic damage. Chromic acid (H2 Cr2 O7(aq)) is a strong acid because hydrogen ions disassociate and stay in solution.

Today, chromic acid is considered a carcinogen by the National Institute of Occupational Safety and Health (NIOSH). Chromic acid (CrO 3 ), Chromic anhydride, Chromic oxide, Chromium(VI) oxide (1:3), Chromium trioxide, Zinc chromate CrO 3 : Dark-red, odorless flakes or powder.

Toxic in contact with skin. (APF = 50) Any air-purifying, full-facepiece respirator with an N100, R100, or P100 filter. 2.2.1 Chrome Holes health hazard. Special Remarks on Fire Hazards: Arsenic reacts with Chromium trioxide with incandescence. Welcome to PubChem! - No smoking Cancer hazard. * Chromic Acid should be handled as a CARCINOGEN--WITH EXTREME CAUTION. Industrial hygiene studies have consistently found problems with skin lesions, nasal ulceration and perforation and other nasal mucosa problems (Table 1). [Note: Often used in an aqueous solution (H 2 CrO 4 ).] Reacts with Sodium or Potassium with incandescence. 5 CDC twenty four seven. Chromium (VI), or hexavalent chromium, is also classified as a carcinogen. It can be present in solution or solid and can be generated as a dust, fume or mist from workplace activities where chromates, dichromates and chromic acid are used. * Chromic Acid can cause reproductive damage. In these processes the bursting of small bubbles of gases generated by electrolysis causes the formation of mists (fine droplets of electrolyte). - No smoking The term chromic acid is usually used for a mixture made by adding concentrated sulfuric acid to a dichromate, which may contain a variety of compounds, including solid chromium trioxide.This kind of chromic acid may be used as a cleaning mixture for glass. Accidents involving chromic acid cleaning solutions can result in burns to both skin and clothing. Many acids are toxic and chromic acid is one of them. Acids are very beneficial substances. KEY AIRBORNE HAZARDS FOR THE METAL INDUSTRY Soluble hexavalent chromium compounds, and in particular chromic acid (chromium trioxide), are commonly used as electrolytes in electroplating and anodising. 58 / Monday, March 26, 2012 / Rules and Regulations 10/18/2013 EN (English) 2/10 P202 - Do not handle until all safety precautions have been read and understood P210 - Keep away from heat, sparks, open flames.
