Ingestion: Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact: Wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Note to Physician: Treat symptomatically
5. Fire Fighting Measures
Flammability of the Product: Flammable.
Auto-Ignition Temperature: 395C.
Flash Points: -27C
Products of Combustion: Carbon dioxide, carbon monoxide, hydrogen chloride, silicon dioxide and fumes.
Fire: Inflammable.
Explosion: Explosive in presence of heat.
Fire Extinguishing Media: Dry powder Dry sand should be preferred. Use dry powder, alcohol resistant foam, carbon dioxide. Flammable liquid and vapor. Do not use a solid (straight) water stream as it may scatter and spread fire. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. Cool containing vessels with water spray in order to prevent pressure build-up, auto-ignition or explosion.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes.
6. Accidental Release Measures
Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.).
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Remove all sources of ignition. Provide proper ventilation. Absorb the material on a porous, inert material such as earth, sand, or vermiculite. Carefully sweep up or swab the material without causing dust/mist. Dispose of in accordance with local regulations.
Large liquid spillages should be contained by use of sand or another inert material. The spillage should be transferred to a suitable container and recovered or disposed of in accordance with local regulations.
7. Handling and Storage
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Do not ingest. Do not breathe dust vapors or mist . Work under hood. Ensure proper ventilation. Provide appropriate exhaust ventilation at places where dust/mist is formed. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.).
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Do not leave the material container open. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like oxidizing agents, strong acids, strong bases, alcohols, amines, aldehydes water. Keep away from ignition sources. Keep contents under inert gas.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: Contains no substances with occupational exposure limit values.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Handle in accordance with good industrial hygiene and safety practice.
