SECTION 2: Hazards identification

OSHA Emergency Overview: A(n) white to off-white paste product with a slight odor. WARNING! Combustible liquid and vapor. May cause eye, skin, nose, throat and respiratory tract irritation. Vapors harmful if inhaled. Harmful if swallowed or absorbed through the skin. Aspiration hazard if swallowed - can enter lungs and cause damage. Refer to other MSDS sections for other detailed information. Effects Of Overexposure - Eye Contact: May cause eye irritation. Effects Of Overexposure - Skin Contact: Harmful if absorbed through the skin. May cause skin irritation. Effects Of Overexposure - Inhalation: Harmful if inhaled, may affect the brain or nervous system causing dizziness, headache or nausea. Dust from dry sanding may cause eye, skin, nose, throat and respiratory tract irritation. Effects Of Overexposure - Ingestion: Harmful or fatal if swallowed. If ingested, may cause depressed respiration. Ingestion may result in obstruction when material hardens. Aspiration of material into the lungs due to vomiting can cause chemical pneumonitis, which can be fatal. Effects Of Overexposure - Chronic Hazards: Repeated or prolonged exposure may cause respiratory system damage. Prolonged and repeated skin contact may cause irritation and possibly dermatitis. NOTICE: Reports have associated repeated and prolonged occupational overexposure to solvents with permanent brain and nervous system damage. Symptoms include: loss of memory, loss of intellectual ability and loss of coordination. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal. The International Agency for Research on Cancer (IARC) has determined that crystalline silica in the form of quartz or cristobalite that is inhaled from occupational sources is carcinogenic to humans (Group 1- carcinogenic to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (published in June 1997) in conjunction with the use of these materials. The National Toxicology Program (NTP) classifies respirable crystalline silica as "known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (Group A2). Breathing dust containing respirable crystalline silica may not cause noticeable injury or illness even though permanent lung damage may be occurring. Inhalation of dust may have the following serious chronic health effects: Excessive inhalation of respirable dust can cause pneumoconiosis, a respiratory disease, which can result in delayed, progressive, disabling and sometimes fatal lung injury. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness and reduced pulmonary function. Smoking exacerbates this disease. Individuals with pneumoconiosis are predisposed to develop tuberculosis. There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by fibrosis of the lungs, skin and other internal organs) and kidney disease. Symptoms include: loss of memory, loss of intellectual ability and loss of coordination.
