Eye Contact: Rinse thoroughly with water for several minutes, lift eyelids, seek medical attention if irritation persists
Skin Contact: Remove contaminated clothing, wash skin with soap and water, seek assistance if rash or irritation develops
Inhalation: Move person to fresh air, call for medical help if cough or irritation remains
Ingestion: Rinse mouth, drink water, do not induce vomiting, consult physician if discomfort occurs
Medical Attention: Treat based on symptoms and general health practice
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Media: Avoid high-pressure water jets that may spread dust
Special Hazards: Material can produce irritating and toxic gases (CO, NOx, HCN) during intense fire
Protective Equipment: Firefighters should put on self-contained breathing apparatus and protective gear
Specific Methods: Isolate area, remove containers from fire zone if possible, cool with water mist
Personal Precautions: Use dust mask, goggles, gloves for cleanup
Environmental Precautions: Avoid discharge into drains, watercourses, or soil
Spill Clean-up: Sweep, vacuum, or shovel into suitable container, minimize dust generation, use non-sparking tools
Disposal: Collect spillage for proper waste treatment; avoid incineration without emission controls
Decontamination: Wash affected area with water after removing material
Handling: Manage containers gently to prevent ruptures, avoid creating airborne dust, ensure clean work area
Personal Protection: Wear appropriate mask and gloves if dusting occurs, wash hands before breaks
Storage Conditions: Keep bags tightly sealed, store in cool, dry, well-ventilated place
Compatibility: Keep away from strong acids, oxidizers, and bases
Incompatible Materials: Moisture-sensitive surroundings, exposure to open flames or heat sources
Special Packaging: Use lined or moisture-resistant sacks or containers for extended life
Exposure Limits: OSHA/ACGIH exposure limit for nuisance dusts: 10 mg/m³ total dust, 3 mg/m³ respirable fraction
Engineering Controls: Use local exhaust ventilation or general room ventilation to control dust
Personal Protective Equipment: Safety goggles, gloves, dust mask or respirator (N95 or better in dusty areas), protective clothing
Hygiene Measures: Wash hands before eating, drinking, smoking, or use of washrooms, keep work clothing separate
Appearance: White to light grey pellets or granules, fine powder possible on surface
Odor: Odorless
pH: Not applicable for pellet; 5.5–7.5 if suspended in water
Melting Point: 350–400°C (decomposition occurs)
Boiling Point: Not applicable
Flash Point: Not flammable in standard use
Autoignition: >400°C
Solubility in Water: Negligible
Vapor Pressure: Not relevant due to solid state
Bulk Density: 0.5–0.8 g/cm³
Explosive Properties: Not explosive
Other Information: Stable physical form at room conditions
Chemical Stability: Stable under normal storage, resistant to hydrolysis under dry conditions
Reactivity: Not reactive with most materials in handling
Conditions to Avoid: Excessive heat, open flames, high humidity
Incompatible Materials: Strong oxidizers, strong acids or bases, reactive chemicals
Hazardous Decomposition Products: Ammonia, oxides of nitrogen, hydrogen cyanide, carbon oxides on combustion
Polymerization: Not expected
Acute Toxicity: Low, oral LD50 in rats >2,000 mg/kg
Dermal Toxicity: Not irritant on intact skin in standard animal models
Eye Irritation: Slight mechanical irritation possible due to dust
Respiratory Sensitization: No evidence of allergenic reactions in humans
Chronic Effects: No carcinogenic, mutagenic, or developmental toxicity reported
Summary: Human exposure mainly results in minor transient irritation related to dust; long-term risks minimal with simple hygiene measures
Ecotoxicity: No significant effect on aquatic organisms at usual concentrations
Persistence/Degradability: Low biodegradation expected due to chemical structure; not readily biodegradable
Bioaccumulation: Low potential due to poor solubility
Mobility in Soil: Material is relatively immobile as solid
Other Adverse Effects: Avoid bulk releases to surface water; proper containment reduces environmental concern
Waste Treatment Methods: Collect in closed, labeled containers; mechanical recycling possible
Landfill: Permitted in controlled landfills that follow local regulations
Incineration: Only in approved facilities with emission controls for ammonia and NOx
Unused Product: Return to supplier or recycle
Contaminated Packaging: Empty containers may retain residues, triple-rinse and dispose as per local legal codes
