HMIS CODES

H=1, F=0, R=0 (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: Ingestion causes stomachache, vomiting and diarrhea. Inhalation: Inhalation causes coughing, sneezing and respiratory problems.. 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.

Medical Conditions Generally Aggravated by Exposure

Persons with pre-existing eye conditions or impaired pulmonary function may be more susceptible to the effects of this product. Exposure: 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.
