Eye Contact: Rinse gently with plenty of cool clean water for 15 minutes, keep eyelids apart, seek immediate medical help if irritation or redness persists
Skin Contact: Remove any contaminated clothing, wash skin with soap and water for no less than 15 minutes, observe for delayed reactions
Inhalation: Move to fresh air, support breathing, initiate artificial respiration if necessary, call emergency services in case of breathing difficulty
Ingestion: Rinse mouth thoroughly, never induce vomiting without professional direction, seek immediate medical attention, monitor for stomach pain or nausea
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical, or foam
Specific Hazards: Burning may produce toxic gases including sulfur oxides and nitrogen oxides, smoke may aggravate pre-existing respiratory conditions
Fire-Fighter PPE: Full protective gear and self-contained breathing apparatus, keep upwind of fire, avoid inhalation of combustion products
Special Procedures: Remove containers from fire area if safe, use water to keep fire-exposed containers cool and prevent rupture
Personal Precautions: Don suitable gloves, eyeshield, and dust mask, limit spread by ventilating area well
Environmental Precautions: Prevent entry into drains, sewers, or waterways, dam spills with inert absorbent material
Clean-Up Methods: Shovel spilled powder carefully to avoid raising dust, sweep into sealable container, dispose as chemical waste, decontaminate area with water after spill cleaned up
Safe Handling: Avoid inhalation or direct contact with skin and eyes, use only in well-ventilated areas, do not eat or drink while using
Storage Requirements: Store in tightly closed original container, keep in cool, dry, well-ventilated locations away from strong acids, oxidizers, and heat sources
Incompatibilities: Strong acids, strong oxidizing agents, moisture
Hygiene Measures: Wash after handling, keep work clothes separate, do not wear contaminated clothing home
Engineering Controls: Use local exhaust ventilation to limit airborne dust or fumes, maintain negative pressure in storage areas
Personal Protection: Wear chemical resistant gloves such as nitrile, use chemical safety goggles, don dust mask or respirator certified for particulates, supply emergency eyewash and safety shower in work area
Exposure Limits: No legislative occupational exposure limit; minimize chronic dust exposure as a best practice

Conditions to Avoid: Excessive heat, direct sunlight, contact with moisture, sources of ignition
Materials to Avoid: Strong oxidizers, reducing agents, strong acids
Hazardous Decomposition: Exposure to strong heat may release oxides of sulfur, nitrogen, and carbon
Reactivity: Negligible hazard under normal storage but reacts with acids and oxidizers with heat evolution
Acute Toxicity: Data limited, based on related compounds exhibits low acute oral and dermal toxicity
Skin Corrosion/Irritation: Contact may redden and irritate skin, repeated exposure may sensitize
Eye Damage/Irritation: Contact stings and causes redness or watering
Inhalation Risks: Dust can irritate nose, throat, and lungs, causing coughing, sneezing, or shortness of breath
Chronic Effects: No reliable data on carcinogenicity, mutagenicity, or reproductive effects
Other effects: Individuals with allergies or chronic skin conditions may react adversely at lower concentrations
Environmental Fate: Water soluble compound moves readily through soil and into waterways
Aquatic Toxicity: Hazardous to fish and aquatic organisms at high concentration; may cause discoloration, reduce water quality, affect photosynthesis in aquatic plants
Persistence/Degradability: Not readily biodegradable, may persist in sediment
Bioaccumulation: No evidence for significant bioaccumulation in aquatic food chains
Soil Mobility: High soil mobility, risk of leaching to groundwater if released in large amounts
Disposal Methods: Collect all waste in sealed, labeled containers, arrange chemical waste disposal through licensed contractor, do not mix with domestic or general waste streams
