Chromium/Iron Oxide Green

SECTION 2: Hazards identification

EMERGENCY OVERVIEW ********************************** Dry, green/black powder with little to no odor. Will not burn or react, but the black iron oxide portion of this product may auto-oxidize if exposed to heat in excess of 176 F (80 C) causing additional heat which may be sufficient to cause packaging to smoulder or ignite. Long-term inhalation can cause lung irritation or chronic respiratory effects. Packaging material can burn or melt in fire, producing toxic smoke and fumes. *************************************************************************************************************************************

HMIS CODES

H=0, F=0, R=0, P=1 (0=Minimal, 1=Slight, 2=Moderate, 3=Serious, 4=Severe)

Potential health effects

Eyes: Non-irritating to the eyes. Excessive exposure to airborne dust may reduce visibility and/or cause unpleasant deposits. Skin: Will not irritate skin and is not likely to cause allergic skin reaction. Irritation to skin or mucous membranes can occur by direct mechanical action or by rigorous skin cleaning necessary for removal of dust. Ingestion: Small amount (less than one ounce/30 grams) swallowed is not likely to cause injury. If large amount ingested, may cause gastric irritation, nausea and diarrhea. Seek medical attention. Inhalation: Not a hazard in normal industrial use. Wear respirator and avoid breathing dust. As with all dusty materials, inhalation may cause respiratory irritation, sneezing, coughing, and runny nose. Human Effects and symptoms of overexposure: Acute: On the basis of Animal Toxicity Data we would expect this product to be non-irritating to the eyes and skin and to be essentially non-toxic by ingestion. However, excessive exposure to airborne dust may reduce visibility and/or cause unpleasant deposits in the eyes, ears, and nose. Irritation to skin or mucous membranes can occur by direct mechanical action or by rigorous skin cleaning necessary for removal of dust. As with all dusty materials, inhalation may cause respiratory irritiation, sneezing, coughing and runny nose. Good personal hygiene and the use of protective creams will minimize this effect. To date, adverse health effects from exposure have not been reported among workers using this pigment. Chronic: Repeated or Prolonged inhalation of trivalent chromium compounds may cause chronic respiratory effects. (ACGIH "Documentation of the Threshold Limit Values"). Other Effects: None known. No chronic effects are known from repeated exposure to iron oxide PIGMENT. Prolonged inhalation (6 to 10 years) of iron oxide FUME has been reported to produce changes in lung x-rays of exposed individuals. This condition, siderosis, is considered to be benign pneumoconiosis that exhibits no adverse health effects. Siderosis has been observed among occupations such as arc-welders where iron oxide FUMES are present. To the best of our knowledge, this condition has not been observed after prolonged exposure to iron oxide pigment. There is no Iron Oxide FUME contained in this product and none should be generated under normal use. Medical Conditions Persons with pre-existing eye conditions or impaired pulmonary function may be more susceptible Aggravated by Exposure: to the effects of this product. Carcinogenicity: IARC: Not Listed NTP: Not Listed OSHA: Not regulated Other: NTP, IARC and ACGIH found "there is sufficient evidence for the carcinogenicity of Chromium and Certain Chromium Compounds both in humans and experimental animals." The Chromium compounds that are considered carcinogenic are Hexavalent chromium compounds. This product is a trivalent chromium compound that contains less than 500 ppm (0.050%) leachable hexavalent chromium. Trivalent chromium is not specifically listed as a carcinogen by NTP, IARC or ACGIH.
