Hazards and Protection.
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Add sodium bisulfite (NaHSO3). Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Trivalent chromium is the most stable oxidation state and hexavalent chromium is the second most stable state. Trivalent, hexavalent chromium.
Can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers) Can react violently with active metals, cyanides, esters, and thiocyanates Avoid contact with water, acids, and bases.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Nonflammable, except when in presence of heat and organic matter.
Fire may produce irritating, corrosive and/or toxic gases.
TLV: ppm; 0.0005 mg/m3 Intended change A2: as Cr (ACGIH 1991-1992).

Hepatic encephalopathy, cerebral edema, and coma may occur. Both trivalent and hexavalent chromium have been found to cross the placental barrier in hamsters and mice. Both were shown to enter the fetus during mid to late gestation. Developmental effects caused by both differed between hamster and mice. Fetal uptake of hexavalent chromium was much greater than that of the trivalent form. Effects on placental tissue could have also affected the fetus.
Gastroenteritis and hemorrhage frequently occur immediately following oral ingestion.
Pulmonary edema, pneumoconiosis, metal fume fever, and bronchial asthma may occur.
Deep perforating ulcers and hypersensitivity dermatitis may be noted. Systemic toxicity has resulted from minimal dermal exposure.
Oral burns and severe corneal injury may result from acute exposure. Chronic inhalation produces deep perforating nasal ulcers (chrome holes).
Induce vomiting, give demulcents and fluids.
Remove to fresh air.
Wash thoroughly with soap and water.
Irrigate with running water for 15 minutes. Consult a physician.
