Potential health effects

Potential health health effects Routes Routes of of of of exposure exposure Inhalation. Ingestion. Skin contact. Eye contact. Eyes Causes eye irritation. High vapor/aerosol concentrations may be irritating. Skin Causes skin irritation. Prolonged or repeated contact with skin may cause redness, itching, irritation and eczema/chapping. Inhalation Harmful if inhaled. May cause irritation to the mucous membranes and upper respiratory tract. In high concentrations, vapors and aerosol mists have a narcotic effect and may cause headache, fatigue, dizziness and nausea. Ingestion Harmful or fatal if swallowed. Ingestion may result in vomiting; aspiration (breathing) of vomitus into lungs must be avoided as even small quantities may result in aspiration pneumonitis. Target Target organs organs Eyes. Respiratory system. Skin. Central nervous system. Reproductive organs.

Potential chronic health

Chronic effects Can cause nervous system damage. May cause adverse reproductive effects - such as birth defects, miscarriages, or infertility based on animal data. Frequent or prolonged contact may defat and dry the skin, leading to discomfort and dermatitis. Chronic effects Organic solvents may be absorbed into the body by inhalation and ingestion and cause permanent damage to the nervous system, including the brain. Frequent or prolonged contact may defat and dry the skin, leading to discomfort and dermatitis. Carcinogenicity This product is not considered to be a carcinogen by IARC, ACGIH, NTP, or OSHA. Skin Skin corrosion/irritation corrosion/irritation Causes skin irritation. Epidemiology No epidemiological data is available for this product. Mutagenicity No data available to indicate product or any components present at greater than 0.1% are mutagenic or genotoxic. Neurological Neurological effects effects High vapor/aerosol concentrations (attainable only at elevated temperatures) may cause central nervous system effects such as dizziness, drowsiness or headaches. Central and/or peripheral nervous system damage. Reproductive Reproductive effects effects Suspected of damaging fertility. Suspected of damaging the unborn child.

Skin Skin contact contact In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention. Wash contaminated clothing before reuse. Destroy or thoroughly clean contaminated shoes. Inhalation Move to fresh air. If breathing is difficult, give oxygen. If breathing stops, provide artificial respiration. Get medical attention. Ingestion Call a physician or poison control center immediately. Do not induce vomiting. If vomiting occurs, the head should be kept low so that stomach vomit doesn't enter the lungs.

Precautionary statements

precautions for for for firefighters firefighters face shield, gloves, rubber boots, and in enclosed spaces, SCBA. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tanks due to fire. Move containers from fire area if you can do so without risk. For massive fire in cargo area, use unmanned hose holder or monitor nozzles, if possible. If not, withdraw and let fire burn out. Some of these materials, if spilled, may evaporate leaving a flammable residue. Cool containers exposed to flames with water until well after the fire is out. Special Special protective protective protective equipment equipment equipment for for As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH fire-fighters (approved or equivalent) and full protective gear. Specific Specific methods methods In the event of fire and/or explosion do not breathe fumes. Use water spray to cool unopened containers. Hazardous Hazardous combustion combustion combustion products products Carbon monoxide and carbon dioxide. 6666. . . . Accidental Accidental Accidental Release Release Release Measures Measures Personal Personal precautions Wear appropriate protective equipment and clothing during clean-up. Keep unnecessary personnel away. Keep upwind. Keep out of low areas. Ventilate closed spaces before entering them. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Local authorities should be advised if significant spillages cannot be contained. Environmental Environmental precautions Prevent further leakage or spillage if safe to do so. Do not contaminate water. Avoid discharge into drains, water courses or onto the ground. Methods Methods for for for containment containment ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Stop the flow of material, if this is without risk. Prevent entry into waterways, sewer, basements or confined areas. Dike the spilled material, where this is possible. Methods Methods for for for cleaning cleaning cleaning up up up up Use only non-sparking tools. All equipment used when handling the product must be grounded. Large Spills: Use a non-combustible material like vermiculite, sand or earth to soak up the product and place into a container for later disposal. Dike far ahead of spill for later disposal. Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Collect in a non-combustible container for prompt disposal. Never return spills in original containers for re-use. Clean surface thoroughly to remove residual contamination. Clean up in accordance with all applicable regulations. J. T. Baker SOLUSORB® solvent adsorbent is recommended for spills of this product. 7777. . . . Handling Handling Handling and and and Storage
