Impurities: Traces of sodium chloride, moisture, and trace metal contaminants depending on production source
Inhalation: Remove from exposure to fresh air, provide artificial respiration if breathing stops, seek medical attention for persistent symptoms
Ingestion: Rinse mouth with water, never give anything by mouth to an unconscious person, seek medical care right away
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water and soap, consult doctor if irritation develops
Eye Contact: Promptly rinse with running water for at least 15 minutes, lift eyelids occasionally, medical assessment if redness or pain persists
Suitable Extinguishing Media: Use dry powder, foam, carbon dioxide; avoid water in large volumes
Special Hazards: Decomposition can release toxic gases including sodium oxides, iron oxides, and hydrogen cyanide
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear
Firefighting Instructions: Evacuate area, approach fire from upwind, do not use direct water jets on substance, prevent runoff from entering waterways
Personal Precautions: Evacuate non-essential personnel, ventilate area, wear approved respiratory protection and gloves
Spill Response: Sweep up carefully without generating dust, place in suitable containers for disposal, wash spill site with water after material pickup
Environmental Precautions: Prevent spilled product from entering sewers or water bodies, notify authorities in case of large spills
Safe Handling: Wear protective gloves, lab coat, goggles, and dust mask if powder forms in the work zone, use in well-ventilated areas
