844-2075 CHROMA-CHEM RAW UMBER

SECTION 2: Hazards identification

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

Potential health effects

Eye contact Irritating. May cause tearing, reddening and/or swelling. May injure eye tissue if not removed promptly. May cause conjunctivitis. Skin Contact A moderate skin irritant based on testing of similar CHROMA-CHEM® base mixtures. Prolonged or repeated contact may cause irritation. Prolonged skin contact with large amounts of ether acetates may cause drowsiness. 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

High vapor concentrations (3000 ppm) of propylene glycol monomethyl ether acetate caused upper respiratory irritation and liver and kidney effects in subchronic animal testing. The relevance of these results to humans is not known. 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. 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. Manganese dioxide dust has caused developmental effects in the absence of maternal effects. Repeated exposure to manganese dioxide may lead to neurological effects and lung effects. 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. This product contains an ingredient that has been shown to produce mutagenic effects in in vivo testing. Because this product is a free-flowing liquid or paste, dust inhalation is not an expected route of exposure.
