Eye Contact: Rinse thoroughly with plenty of water for at least 15 minutes, holding eyelids open. Remove contact lenses if present and easy to do. Seek immediate medical attention.
Skin Contact: Wash affected area with plenty of soap and water for at least 15 minutes. Remove contaminated clothing. Get medical help if irritation persists.
Inhalation: Move to fresh air. Rest in position comfortable for breathing. Get medical advice if symptoms like cough, dizziness, or headache occur.
Ingestion: Rinse mouth. Never induce vomiting unless instructed by medical personnel. Drink a small amount of water if conscious. Contact poison control or call a doctor immediately.
Additional Advice: Make sure responders use personal protection like gloves and goggles. Show medical team this sheet if possible.
Suitable Extinguishing Media: Water mist, dry chemical powder, foam, or carbon dioxide
Unsuitable Media: Straight water jets may spread material
Hazardous Combustion Products: Nitrogen oxides, carbon dioxide, carbon monoxide
Specific Hazards: Decomposition in heat or fire releases toxic gases. Dust-air mixtures may form explosive clouds.
Protective Equipment for Firefighters: Full protective suit, self-contained breathing apparatus
Additional Information: Use water spray to cool closed containers exposed to fire. Avoid runoff into watercourses.
Personal Precautions: Wear gloves, eye protection, and dust mask. Evacuate unprotected personnel.
Environmental Precautions: Prevent entry into drains, surface water, or soil. Notify authorities in case of significant spill.
Containment: Avoid dust generation. Contain spill using inert absorbent like sand. Do not touch spilled material.
Cleanup Procedures: Use non-sparking tools. Sweep up and place into labeled, sealed containers for disposal. Wash area with plenty of water after removal.
Disposal: Collect for proper disposal in accordance with local regulations.
Handling: Avoid breathing dust. Prevent contact with skin, eyes, and clothing. Wash thoroughly after handling and before eating or drinking. Use only with adequate ventilation.
Conditions for Safe Storage: Keep container tightly closed in a dry, cool, and well-ventilated place, away from heat sources, sparks, and incompatible substances.
Incompatibles: Strong acids, strong bases, oxidizing agents, reducing agents
Storage Class: Chemical Storage (non-flammable, toxic solid)
Special Requirements: Store away from direct sunlight and sources of moisture
Engineering Controls: Work under a fume hood or local ventilation system. Use natural ventilation only if dust generation is highly unlikely.
Exposure Limits: No specific occupational exposure limit assigned; use general guidelines for nuisance dust (10 mg/m3 total dust, 5 mg/m3 respirable fraction)
Personal Protective Equipment: Chemical safety goggles, gloves (nitrile or neoprene), lab coat or apron, approved dust mask or respirator (P2 rating or above) if dust creation expected
Hygiene Measures: Wash hands before breaks and after work. Avoid eating, drinking, or smoking while working. Wash contaminated clothing before reuse.
