824-2003 CHROMA-CHEM RAW UMBER

SECTION 2: Hazards identification

*** EMERGENCY OVERVIEW *** Form-paste Color-brown Odor-Petroleum distillate odor. May cause eye, skin and respiratory tract irritation. Combustible liquid and vapor.

Potential health effects

Eye contact According to test results on similar colorant base mixtures, this product is classified as a moderate eye irritant. May cause tearing, reddening and/or swelling. Skin Contact Prolonged or repeated contact may result in defatting and drying of the skin causing skin irritation and dermatitis (rash). Moderate irritant according to test results on similar base mixtures. Inhalation Possibly irritating. Excessive inhalation of solvent vapors may cause nasal and respiratory irritation and central nervous system effects including dizziness, weakness, fatigue, nausea, headache, possible unconsciousness and even death. Ingestion May cause gastrointestinal irritation, nausea, vomiting, and diarrhea.

Health hazards

Prolonged inhalation of iron oxide dust is known to produce a condition known as siderosis. On X- rays it appears to be a benign pneumoconiosis and is not associated with pulmonary fibrosis or disability unless there is concurrent exposure to other fibrosis producing materials such as silica. Health studies have shown that many petroleum hydrocarbons pose potential human health risks which may vary from person to person. As a precaution, exposure to liquids, vapors, mists or fumes should be minimized. Some studies have linked exposure of carbon black dust to lung effects. IARC classifies carbon black as a Category 2B Carcinogen (known animal carcinogen, possible human carcinogen) based on inhalation studies. However, the manufacturers of carbon black state that epidemiologic studies of workers in the carbon black industry in the U.S. and W. Europe show no significant adverse health effects due to occupational exposure. Overexposure to crystalline silica dust causes lung effects. There is sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica (IARC 1,OSHA). Crystalline Silica has been assigned the A2 carcinogen designation by ACGIH, suspected human carcinogen. Repeated inhalation of crystalline silica may cause kidney disease, auto-immune disease, and lymph node effects. Because this product is a free-flowing liquid or paste, dust inhalation is not an expected route of exposure.
