Additives: None added, not stabilized
Inhalation: Remove the person to fresh air; if coughing or breathing trouble starts, call a physician, watch for airway irritation with dust
Eye Contact: Flush with water for at least 10 minutes, pull back eyelids, seek help if redness persists
Skin Contact: Wash area with soap and water, take off contaminated clothes; persistent rash or irritation? Seek care
Ingestion: Rinse mouth, do not force vomiting, consult medical help right away, bring product info
Notes for Doctors: Supportive care, treat symptoms, no specific antidote known
Suitable Extinguishing Media: Use foam, dry powder, or carbon dioxide, avoid high-pressure water that can spread dust
Specific Hazards: May form combustible dust-air mixtures under certain conditions, burns with strong smoke above 200°C, toxic fumes (carbon oxides) possible
Protective Equipment for Firefighters: Wear full-body protection and breathing apparatus, stay upwind if smoke builds
Firefighting Instructions: Clear area, water spray for cooling in risk zone, prevent run-off from entering sewers or water sources
Personal Precautions: Avoid breathing dust, ventilate area, use proper PPE (gloves, goggles, masks)
Environmental Precautions: Keep spills out of drains and surface water if safe
Spill Clean-Up: Sweep or suck up spill promptly, place in labeled waste bin, dampen surfaces to minimize dust
Decontamination: Wash spill area with water and mild soap; monitor air for dust in large spills
Report: Large releases to local authority as per rules
Handling: Avoid generating dust, keep container closed, do not eat, drink or smoke during use, wash up after contact
Safe Storage: Keep in dry, cool and well-ventilated spot, close tightly, seal any open bags, store away from strong acids and oxidizers
Storage Materials: Use original packaging or compatible drum, brace to avoid tip-over, avoid mechanical shock
Fire Prevention: Keep away from ignition sources, ground containers to minimize static
Hygiene: Provide water and washing station near work area
Exposure Limits: No specific legal workplace exposure levels; keep dust under 1 mg/m³ as a guide
Engineering Controls: Local exhaust or general ventilation, especially when handling powders
Respiratory Protection: Use dust mask (P2) for powder or large handling, standard filter respirators in industrial uses
Eye Protection: Wear safety glasses or goggles
Skin Protection: Gloves made of nitrile or PVC, lab coats, long sleeves in factories
Other Protective Gear: Use aprons for larger uses or if risk of splash, have eyewash shower handy
Appearance: White, free-flowing powder or crystalline solid
Odor: Odorless
Solubility: Mildly soluble in water (0.47 g/L at 25°C), more in alcohols, not in most organic solvents
Melting Point: 220-242°C (decomposes above 230°C)
Boiling Point: Not applicable – decomposes before boiling
Vapor Pressure: Negligible under standard conditions
Density: 1.35-1.38 g/cm³
pH (solution): 6.0–8.0 in water
Flash Point: Not relevant
Other Properties: Stable under normal pressure and temperatures, not volatile, sticks to moisture if left open
Chemical Stability: Stays stable in closed containers under standard temperatures
Reactivity: Reacts with acids, oxidizes near strong agents, may give off fumes if overheated
Hazardous Reactions: High heat leads to slow breakdown, may produce formic acid, carbon monoxide; not shock-sensitive, doesn’t self-react
Conditions To Avoid: Avoid moisture, direct flame, sparks, and incompatible chemicals
Incompatible Materials: Strong acids and bases, oxidizers, chloroformates
Decomposition Products: Carbon monoxide, carbon dioxide, possibly small organic vapors
Acute Toxicity: Low oral toxicity (LD50 >5000 mg/kg, rat), inhalation not acutely toxic in standard amounts
Skin Corrosion: Not classified as corrosive, may dry or mildly irritate skin after long exposure
Eye Damage: Dust may cause pain, redness, possible conjunctivitis
Respiratory Sensitization: None, although dust can cause coughing, mild soreness
Chronic Exposure: No hard evidence of chronic illness or cancer; monitor for skin dryness with repeated handling
Other Effects: No reproductive or genetic effects known, not listed as known carcinogen or mutagen
Ecotoxicity: Not classified as harmful to aquatic life, but large amounts could disrupt oxygen in water by forming floating solids
Persistence and Degradability: Breaks down in soils and water through bacteria, decomposes slowly in sunlight
Bioaccumulation: Not expected, low potential (log Kow ~0.24)
Mobility in Soil: Moves slowly, sticks to particles
Other Adverse Effects: Avoid direct discharge into waterways, encourage containment, not approved for direct environmental disposal
Waste Handling: Collect as non-hazardous industrial waste, use dry method, store in sealed labeled container
Methods of Disposal: Landfill according to local regulations, do not burn outside incinerators, recycling for residue compounds possible in some plants
