説明 of first aid measures: In case of inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. In case of skin contact: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. In case of eye contact: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical attention. In case of ingestion: Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cups of milk or water. Most important symptoms and effects, both acute and delayed: Inhalation: Aspiration may lead to pulmonary edema. Contains crystalline silica, which may lead to respiratory abnormalities and silicosis. Inhalation of dusts causes severe irritation of the upper respiratory tract, gastrointestinal disturbances, albuminuria, gradual loss of weight, and increasing weakness. May cause burning sensation in the chest. Eyes: May cause chemical conjunctivitis and corneal damage. Skin contact: May cause irritation and dermatitis; may cause cyanosis of the extremities. Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhoea, ingestion of large amounts may cause CNS depression. Indication of any immediate medical attention and special treatment needed: Treat symptomatically. Show this safety data sheet to a physician or emergency room.

Section 5: Fire-Fighting Measures

Extinguisher media: Suitable extinguisher media: Use water spray to cool fire-exposed containers. Use dry sand, Met-L-X powder, or G-1 graphite powder. Do NOT get water inside containers. Use dry sand, graphite powder, dry sodium chloride-based extinguishers. Unsuitable extinguishing media: Do not use water, CO2 or foam directly on fire itself.

Further information: Standard procedure for chemical fires. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Section 6: Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Personal precautions: Clean-up personnel should wear appropriate respiratory protective equipment when addressing fine material. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Environmental precautions: Prevent product from entering drains. Prevent further leakage or spillage if safe to do so. Local authorities should be advised if significant spillages cannot be contained. Methods for containment and cleaning up: Methods for cleaning up: Land Spill: Silicon Metal spilled on the land represents minimal hazard. Avoid the use of compressed air to manoeuvre spills or leaks of fine material. Fine material should be swept up or vacuumed using explosionproof equipment. Keep dry material and wet material separated. Place cleaned up material in disposal container. Avoid repackaging wet materials in sealed containers.

Reference to other sections: Treat recovered material as described in the section "Disposal considerations".

Section 7: Handling and Storage

Precautions for safe handling: Advice on safe handling: Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue (liquid and/or vapor) and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Do not allow contact with water. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Keep from contact with moist air and steam. Hygiene measures: Do not eat, drink or smoke when using this product. Conditions for safe storage, including incompatibilities: Requirements for storage areas and containers: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammable-area. Store protected from moisture.

Section 8: Exposure Controls/Personal Protection

Control parameters: Occupational exposure limits: ACGIH: 10 mg/m 3 TWA NIOSH: 10 mg/m 3 TWA (total dust); 5 mg/m 3 TWA (respirable dust) OSHA: Final PELs 15 mg/m 3 TWA (total dust); 5 mg/m 3 TWA (respirable fraction) OSHA: Vacated PELs Silicon: 10 mg/m 3 TWA (total dust); 5 mg/m 3 TWA (respirable fraction). Exposure controls: Appropriate engineering controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels. Individual protection measures, such as personal protective equipment: Eye/face protection: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Hand protection: Use chemical resistant gloves. Examples of preferred glove barrier materials include: Butyl rubber, Neoprene, Nitrile/butadiene rubber, Polyethylene, Ethyl vinyl alcohol laminate, polyvinyl alcohol, Polyvinyl chloride. Body protection: Protective gear to prevent skin exposure. Respiratory protection: respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Section 10: Stability and Reactivity

Reactivity: No dangerous reaction known under conditions of normal use. Chemical stability: Stable under normal conditions. Possibility of hazardous reactions: No dangerous reaction known under conditions of normal use. Conditions to avoid: Silicon metal powders or fines can explode or deflagrate and should be handled to prevent fines from becoming airborne in concentration that exceed the Minimum Explosive Concentration. Silicon particles suspended in air can cause dust deflagrations. Avoid generating sparks and other ignition sources (e.g. welding) in areas with high dust concentrations. Addition of wet material to molten metal may cause explosions. Incompatible materials: Acids and strong bases. Hazardous decomposition products: Contact with acids may result in the generation of silane gas (SiH4), a spontaneously combustible gas. Highly flammable hydrogen gas (H2) may be formed if silicon metal comes in contact with moisture, acids or bases. A reaction with hydrofluoric acid (HF) or nitric acid (HNO3) leads to the formation of toxic gases such as silicon tetrafluoride (SiF4) or nitrous oxide gases (NOx). Wet product will form highly flammable hydrogen gas if added to molten metal, due to decomposition of water.
