Skin: Immediately flush skin with plenty of water for at least 15 minutes. Remove and wash contaminated clothing and shoes before reuse. Get medical attention if irritation develops.
Eyes: Immediately flush eyes with plenty of water for 15 minutes, occasionally lifting upper and lower eyelids. Hold eyelids apart during irrigation. Get medical attention.
Inhalation: Remove person to fresh air. If breathing is difficult, give oxygen. If not breathing administer artificial respiration. Get medical attention.
Section 5. Fire Fighting Measures
Fire/Explosion: Not considered to be a fire and explosion hazard.
Extinguishing Medium: Water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Special hazards arising from the substance/ mixture: Fumes including Carbon monoxide (CO) Carbon dioxide (CO2), Nitrogen oxides and Ammonia.
Fire Fighting Instructions: Use suitable protective equipment for surrounding fire.
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. Fire-extinguishing work is done from the windward and a suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.
Section 6. Spills and Disposals
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.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment cleanup procedures and Storage: Do not inhale dust, vapors, mist, or gas. Avoid dust formation. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g., sand, earth, diatomaceous earth, vermiculite). Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law.
Section 7. Handling and Storage
Precautions for safe handling: Avoid prolonged or repeated exposure. Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. 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. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
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. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents, strong acids. Storage: Room temperature.
Section 8. Exposure Controls & Personal Protection
Exposure Limits: No data available.
Engineering Controls: Use adequate exhaust ventilation to keep airborne concentrations below the allowable exposure limit.
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.
