Ingestion - If it is swallowed, if conscious, give plenty of water. Immediately call a physician. Never give anything by mouth to an unconscious person.
Inhalation - Remove to fresh air. Give oxygen if breathing is difficult; give artificial respiration if breathing has stopped. Get medical attention.
5. FIREFIGHTING PROCEDURES
Extinguisher Media: Use media suitable to extinguish surrounding fire. Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
Special hazards arising from the substance or mixture: Carbon oxides and fumes.
Extinguishing Media Not recommended: Avoid using solid water jet as it may scatter the 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.
6. SPILL OR LEAK PROCEDURES
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: Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g., sand, earth, diatomaceous earth, vermiculite). Vacuum or sweep up and remove to an approved disposal container.
7. SPECIAL PRECAUTIONS
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. 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. Storage: Preserve in tight containers. Room Temperature. Recommended in a cool and dark place, <15C.
8. SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): None needed under normal conditions of use with adequate ventilation. NIOSH approved equipment should be worn if PELs are exceeded.
Exposure Limits: This product does not contain any hazardous materials with occupational exposure limits established by the region-specific regulatory bodies.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible.
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.
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.
