SECTION 2: Hazards identification

EMERGENCY OVERVIEW: Harmful if inhaled. Harmful if absorbed through skin. Causes eye irritation. Causes skin irritation. Vapors irritating to eyes and respiratory tract. Flammable liquid and vapor. EYE: May cause eye burns. SKIN: May cause skin irritation. Prolonged contact with the skin can cause chemical burns. Harmful if absorbed through the skin. Skin contact may aggravate an existing dermatitis. INHALATION: Exposure to high concentrations of vapors may cause dizziness, breathing difficulty, headaches or respiratory irritation. Extremely high concentrations may cause drowsiness, staggering, confusion, unconsciousness, coma or death. Excessive inhalation of vapors can cause nasal and respiratory irritation. Liquid or vapor may be irritating to skin, eyes, throat or lungs. Prolonged inhalation of dusts containing free silica may result in the development of a disabling pulmonary fibrosis(lung disease) known as silicosis. Intentional misuse by deliberately concentrating and inhaling the contents of this product can be harmful or fatal. Respiratory symptoms associated with pre-existing lung disorders may be aggravated by exposure to material(s) is this product. INGESTION: Moderately toxic. May cause stomach discomfort, nause, vomiting, diarrhea, and narcosis. PAGE 4 May cause serious health effects if swallowed. Aspiration of material into the lungs if swallowed or if vomiting occurs can cause chemical pneumonitis which can be fatal. May cause nausea, vomiting and diarrhea.

Potential chronic health

Chronic overexposure to a component or components in this material has been found to cause the following effects in laboratory animals: Kidney damage Eye damage Lung damage Liver damage Spleen damage Anemia --------------------------------------------------------------------------- QUEST INDUSTRIAL PRODUCTS 03769 683194 .6B --------------------------------------------------------------------------- Brain damage Chronic overexposure to a component or components is this product has been suggested as a cause of the following effects in humans: Liver damage Cardiac abnormalities Reports have associated repeated and prolonged overexposure to solvents with permanent brain and nervous system damage. Repeated breathing or skin contact of methyl ethyl ketone may increase the potency of neurotoxins such as hexane if exposures occur at the same time. Central nervous system depression, shock, coma, visual disturbances, and death. Onset of symptoms may be delayed as long as 30 hours. Rats exposed to titanium dioxide dust at 250 mg/m3 developed lung cancer, however, such exposure levels are not attainable in the workplace with this material. The exposure risk of crystalline silica is higher when the respirable portion is available for exposure. The risk of exposure many be reduced when encapsulated in a coating. The risk of cancer depends on the duration and level of exposure to dust from sanding surfaces or mist from spray applications. Product contains toluene which may be harmful to the fetus based on animal studies. Repeated exposure to toluene has been associated with high frequency hearing loss in laboratory animals. The human consequences of this finding is uncertain. In April 1996, The International Agency for Research on Cancer (IARC) published Monograph 65 which reclassifies Carbon Black into Group 2B (possibly carcinogenic to humans). In February 2000 the International Agency for Research on Cancer (IARC) classified ethylbenzene as possibly carcinogenic to humans (Group 2B) on the basis of sufficient evidence for carcinogenicity in experimental PAGE 5 animals but inadequate evidence for cancer in humans.
