aquatic environment.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Not normally a hazard due to physical form of product.  

SKIN

  Irritation and skin reactions are possible with sensitive skin.  

INHALED

  Not normally a hazard due to non-volatile nature of product.  

CHRONIC HEALTH EFFECTS

  Primary route of exposure is usually by skin contact/eye contact.  Chromium(III) is an essential trace mineral. Chronic exposure to chromium(III) irritates the airways, malnourishes the liver and kidneys, causes fluid in the lungs, and adverse effects on white blood cells, and also increases the risk of developing lung cancer. Chromium (VI) can irritate the skin, eyes and airways. Allergic reactions can involve both the skin and airways, and the compounds can diminish taste and smell, discolor the skin and eyes, cause blood disorders and damage the liver, kidneys, digestive tract and lungs. It predisposes humans to cancers of the respiratory tract and digestive system. Ulceration to the skin can occur, and, chromium(VI) is one of the most allergenic substances known.  Exposure of the material to temperatures greater than 900 deg. C. may  cause increased quantities of crystalline silicas (including cristobalite)  to form.  At elevated temperature in an oxidizing environment small amounts of the  chromium content may convert to hexavalent Chromium, CrVI  Used, fired refractory materials are potentially more harmful than new refractories. Chromite containing materials when exposed to high temperatures in oxidising furnaces may be converted or part converted to chromium VI compounds, i.e. chromates; these materials present an increased hazard for skin contact or if present in inhaled dust. Chromates are recognised as carcinogens and have a much lower Exposure Standard than chromite, i.e. chromium III compounds. Exposure to fired refractories is more likely when rebricking, repairing, rebuilding and demolishing old furnaces. Chromates are water soluble and hence may be spread if water spray is used to suppress dust.
