Manufacturer/Importer/Distributor information Manufacturer Supplier GrafTech Brasil Participações Ltda. Rodovia BA 522, Km 7, S/N, Distrito Industrial Candeias - Bahia Emergency number For Chemical Emergency ONLY, call CHEMTREC at: , Manufacturer Graftech International Holdings Inc Snow Road Parma, Ohio Contact person Dave Mieskowski Dave.Mieskowski@graftech.com 2. Hazards identification Classification of the substance or mixture Physical hazards Health hazards Environmental hazards Other hazards which do not result in classification GHS labeling elements, including precautionary statements Hazard symbol(s) Signal word Hazard statement(s) Precautionary statement(s) Prevention Response Storage Disposal Other information No symbol. No signal word. Observe good industrial hygiene practices. Wash hands after handling. 3. Composition/information on ingredients Substance Store away from incompatible materials. Dispose of waste and residues in accordance with local authority requirements. Dusts may irritate the respiratory tract, skin and eyes. Dust and fumes generated from the material can enter the body by inhalation. High concentrations of dust and fumes may irritate the throat and respiratory system and cause coughing. Frequent inhalation of dust over a long period of time increases the risk of developing lung diseases. Prolonged skin contact may cause redness, irritation and dry skin. May cause eczema-like skin disorders (dermatitis). Ingestion of dusts generated during working operations may cause nausea and vomiting. Prolonged and repeated overexposure to dust can lead to pneumoconiosis. Pre-existing pulmonary disorders, such as emphysema, may possibly be aggravated by prolonged exposure to high concentrations of carbon dusts.

CLP: Regulation No. 1272/2008. DSD: Directive 67/548/EEC. All concentrations are in percent by weight unless ingredient is a gas. Gas concentrations are in percent by volume. 4. First-aid measures First-aid measures Inhalation Skin contact Eye contact Ingestion Most important symptoms/effects, acute and delayed Notes to physician Move injured person into fresh air and keep person calm under observation. For breathing difficulties, oxygen may be necessary. Get medical attention. Wash contact areas with soap and water. Get medical attention if irritation develops or persists. If skin irritation or an allergic skin reaction develops, get medical attention. Flush thoroughly with water for at least 15 minutes. Do not rub eye. Remove any contact lenses and open eyelids wide apart. If irritation occurs, get medical assistance. Rinse mouth thoroughly if dust is ingested. Get medical attention if any discomfort continues. Exposed individuals may experience eye tearing, redness, and discomfort. May cause eczema-like skin disorders (dermatitis). Treat symptomatically. 5. Fire-fighting measures Means of fire extinguishing Suitable extinguishing media Unsuitable extinguishing media Specific hazards arising from the chemical Special fire fighting procedures Protective measures taken by fire fighting crews Specific methods Dust: Extinguish with foam, carbon dioxide, dry powder or water fog. None. Thermal decomposition may produce smoke, oxides of carbon and lower molecular weight organic compounds whose composition have not been characterized. Self-contained breathing apparatus and full protective clothing must be worn in case of fire. Use standard firefighting procedures and consider the hazards of other involved materials. Use standard firefighting procedures and consider the hazards of other involved materials. 6. Control measures for spills and leaks Personal precautions, protective equipment and emergency procedures To be taken by those who are not involved in rendering emergency services To be taken by those who are involved in rendering emergency services Environmental precautions Methods and materials for containment and cleaning up Other issues relating to spills and releases Emergency procedures Avoid generation and spreading of dust. Avoid inhalation of dust and contact with skin and eyes. Wear suitable protective clothing and gloves. See Section 8 of the MSDS for Personal Protective Equipment. Use personal protection recommended in Section 8 of the MSDS. Do not allow material to enter storm or sanitary sewers, groundwater or soil. Collect dust using a vacuum cleaner equipped with HEPA filter. If not possible, gently moisten dust with water fog before it is collected with shovel, broom or the like. Collect in approved containers and seal securely. Containers must be labeled. For waste disposal, see Section 13 of the MSDS. Avoid dust formation. Collect dust using a vacuum cleaner equipped with HEPA filter. If not possible, gently moisten dust with water fog before it is collected with shovel, broom or the like. Collect in approved containers and seal securely. Containers must be labeled. For waste disposal, see Section 13 of the MSDS.

3 3 / 6 7. Handling and storage Precautions for safe handling Use work methods which minimize dust production. Avoid inhalation of dust and contact with skin and eyes. Wear appropriate personal protective equipment. Carbon dust is electrically conductive. Take precautionary measures against static discharges when there is a risk of dust explosion. Use explosion-proof electrical equipment if airborne dust levels are high. Keep away from heat, spark, open flames and other sources of ignition. Keep the workplace clean. Observe good industrial hygiene practices. Conditions for safe storage, including any incompatibilities 8. Exposure controls/personal protection Control parameters Keep away from heat, spark, open flames and other sources of ignition. Store away from incompatible materials. Follow standard monitoring procedures. Occupational exposure limits No exposure limits noted for ingredient(s). Biological limit values Appropriate engineering controls Personal protective measures No biological exposure limits noted for the ingredient(s). Provide sufficient ventilation for operations causing dust formation. Mechanical ventilation or local exhaust ventilation is required. Provide explosion-proof ventilation for high dust concentrations. Provide access to washing facilities including soap, skin cleanser and fatty cream. Eyes and face protection Wear safety glasses with side shields (or goggles). Skin protection Hand protection Other Respiratory protection Thermal hazards Hygiene measures 9. Physical and chemical properties Wear suitable protective gloves to prevent cuts and abrasions. Suitable gloves can be recommended by the glove supplier. Wear appropriate clothing to prevent repeated or prolonged skin contact. In case of inadequate ventilation or risk of inhalation of dust, use suitable respiratory equipment with particle filter. Wear appropriate thermal protective clothing, when necessary. Always observe good personal hygiene measures, such as washing after handling the material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove contaminants.
