CDC twenty four seven. At concentrations above the NIOSH REL, or where there is no REL, at any detectable concentration: (APF = 10,000) Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode(APF = 10,000) Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained positive-pressure breathing apparatus. Cancer hazard. * Chromic Acid should be handled as a CARCINOGEN--WITH EXTREME CAUTION.

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. Handle with extreme caution. [Note: Often used in an aqueous solution (H 2 CrO 4 ).] effects in the aquatic environment. Possible risk of impaired fertility. There is a drawback though. Toxic in contact with skin. Chromium (VI), or hexavalent chromium, is also classified as a carcinogen. Chromic acid is an oxidizing agent that is irritating to all exposed tissues. Chromic acid may also refer to the molecular species, H 2 CrO 4 of which the trioxide is the anhydride. Protect containers from physical damage. One study concluded the latency period for chromium induced lung cancer is greater than 20 years; exposure duration may be as low as two years. A violent reaction or flaming is likely in the reaction of chromium oxide and aluminium powder. health hazard. Industrial hygiene studies have consistently found problems with skin lesions, nasal ulceration and perforation and other nasal mucosa problems (Table 1). Chromic acid is a powerful oxidizing agent that is both toxic and corrosive and can explode on contact with organic materials. Benzene ignites on contact with chromium trioxide. They are widely used in industry in the production of many different products. 77, No. Mini mize exposure to air and light. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. This is why (aq), meaning ''aqueous,'' is written after its formula. In these processes the bursting of small bubbles of gases generated by electrolysis causes the formation of mists (fine droplets of electrolyte).

Today, chromic acid is considered a carcinogen by the National Institute of Occupational Safety and Health (NIOSH). HAZARDS IDENTIFICATION OSHAHazards Storage Area: CORROSIVE, ACID Store in a cool, dry, corrosive materials storage area. 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. Reacts with Sodium or Potassium with incandescence.
