General Advice: Move exposed individual away from product and contaminated area
Inhalation: Move to fresh air, monitor breathing, administer oxygen if needed, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing immediately, rinse affected area with plenty of water for at least 15 minutes, seek medical advice for irritation or burns
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if possible, continue rinsing, seek prompt medical care
Ingestion: Rinse mouth; do not induce vomiting; call poison center or physician right away; never give anything by mouth to an unconscious person
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Strong water jet may spread material
Fire Hazards: Not flammable but thermal decomposition at elevated temperature releases toxic and corrosive fumes — mainly sulfur oxides, nitrogen oxides, possibly ammonia
Special Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective gear, avoid breathing combustion products
Precautions for Firefighters: Use water spray to keep surrounding containers cool, dike runoff water for proper disposal
Personal Precautions: Wear chemical-resistant gloves, protective eyewear, suitable respiratory protection, avoid creating dust
Environmental Precautions: Prevent product from entering drains or natural waterways, contain spill
Methods for Cleanup: Scoop up spilled material with non-sparking tools, place in a suitable container for disposal, ventilate the area, wash residues away with copious water, avoid raising dust, dispose of waste following local regulations
Handling: Use only in well-ventilated areas, minimize dust generation and accumulation, avoid inhalation, ingestion, or skin/eye contact, keep container tightly closed when not in use
Storage Conditions: Store in cool, dry, well-ventilated location away from incompatible substances—bases, oxidants, nitrates, hypochlorites, moisture
Packaging Materials: Store in containers made from compatible corrosion-resistant material, label all vessels clearly
Stock Management: Check inventory regularly for leaks, damaged containers, or unmarked product
Occupational Exposure Limits: No established permissible exposure limit (PEL) or threshold limit value (TLV) by OSHA or ACGIH; dust should not be inhaled
Engineering Controls: Local mechanical exhaust ventilation, process enclosure or other engineering controls to keep exposure levels below recommended limits
Personal Protective Equipment: Chemical splash goggles, face shields, chemical-resistant gloves (nitrile, neoprene, or rubber), long-sleeved protective clothing, dust mask or approved respirator if dust levels exceed recommendations
Hygiene Practices: Remove contaminated clothing before entering eating or break areas, wash thoroughly after handling, do not eat, drink, or smoke in use areas
