Inhalation: Remove person to fresh air, allow comfortable breathing, seek medical attention if persistent symptoms develop
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, see a physician for irritation or sensitivity
Eye Contact: Rinse gently with water several minutes, remove contact lenses if present and easy, consult a doctor for continued irritation
Ingestion: Rinse mouth, do not induce vomiting without medical advice, seek prompt medical care especially if large amounts consumed or symptoms appear
Notes for Physician: Treat symptomatically, no specific antidote known
Suitable Extinguishing Media: Water spray, dry chemical, foam or carbon dioxide, avoid high-pressure water jets that may spread dust
Specific Hazards: Combustible at elevated temperatures, hazardous fumes including oxides of nitrogen and carbon can form in fire
Protective Equipment for Firefighters: Wear full turnout gear and self-contained breathing apparatus, prevent run-off from entering sewers or waterways
Special Procedures: Cool containers with water spray far from fire, avoid dust generation and inhalation, evacuate personnel from area if risk of explosion from dust cloud exists
Personal Precautions: Wear gloves, goggles, and protective clothing, avoid creating dust, use respiratory protection if airborne dust likely
Environmental Precautions: Prevent spillage from entering watercourses, drains, or soil, contain by diking if possible
Clean-Up Methods: Sweep up promptly with methods that minimize dust, transfer to suitable waste container, ventilate area, dispose according to local regulations
Decontamination: Wash affected surfaces thoroughly with water and detergent
Handling: Avoid inhaling dust, keep containers tightly sealed, work in well-ventilated areas, use good industrial hygiene practices such as washing hands before eating or drinking
Technical Measures: Use tools and equipment made for dust control, ground/bond containers to minimize static discharge
Storage Conditions: Store in cool, dry, well-ventilated location, keep away from heat or ignition sources, protect from moisture and incompatible substances like acids and strong oxidizers
Container Materials: Use polyethylene-lined or fiber drums, clearly labeled and undamaged
Exposure Limits: No established exposure limit values for benzoguanamine, recommended to minimize dust exposure, monitor air for nuisance particles
Engineering Controls: Local exhaust ventilation or dust extraction systems, closed handling systems where practical
Respiratory Protection: Dust mask or respirator approved for fine particulates
Eye Protection: Chemical splash safety goggles
Skin Protection: Impervious gloves (nitrile or PVC), long sleeves, lab coat or coveralls
Hygiene Measures: Wash thoroughly after handling, avoid eating, drinking, or smoking in work area, remove contaminated clothing and launder before reuse
Appearance: White to off-white crystalline powder
Odor: Odorless or slight characteristic
pH: Slightly basic in aqueous suspension
Melting Point: 221 – 225°C
Boiling Point: Decomposes before boiling
Flash Point: Not readily flammable as solid, dust could create explosion risk
Solubility: Poorly soluble in water, more soluble in organic solvents like ethanol and acetone
Vapor Pressure: Negligible at room temperature
Density: 1.4 – 1.6 g/cm³
Partition Coefficient (log Kow): Not significant, low mobility in environment
Other Properties: Stable under normal temperatures and pressures, non-volatile in solid state
Chemical Stability: Stable under recommended handling and storage, may degrade under strong heat or light
Possibility of Hazardous Reactions: Polymerization does not occur spontaneously, should be kept away from strong oxidants which could cause decomposition
Conditions to Avoid: Excessive heat, contact with acids or strong bases, exposure to flame or spark
Incompatible Materials: Acids, chlorinating agents, strong oxidizing chemicals
Hazardous Decomposition Products: Emits toxic gases including ammonia, nitrogen oxides, carbon monoxide and dioxide upon burning or decomposition
Acute Toxicity: Low oral acute toxicity, higher doses could cause gastric distress, ingestion irritates the gastrointestinal tract
Dermal Toxicity: Practically non-toxic through normal skin contact, prolonged exposure could dry or irritate skin
Eye Irritation: Dust contact may cause redness and discomfort
Inhalation Toxicity: Particles can irritate nose, throat, and lungs; excessive exposure rare in controlled environments
Chronic Effects: No evidence of carcinogenicity or reproductive risk reported, absence of long-term studies on chronic exposure
Sensitization: Not a known sensitizer based on industry surveys and workplace experience
Additional Information: Toxicity data are based on closely related triazine compounds where gaps exist
Ecotoxicity: Harmful in aquatic environments at high concentrations, may disrupt microorganisms and small aquatic species
Persistence and Degradability: Moderately persistent in soil and water, slow degradation by bacteria and sunlight
Mobility in Soil: Binds to particulate matter, unlikely to travel far from release site
Bioaccumulation Potential: Low, not expected to concentrate in animals or plants
Other Adverse Effects: Large accidental releases can harm aquatic habitats, prompt clean-up important
Waste Disposal Methods: Collect spilled material in sealed containers, send to licensed chemical waste handler, comply with national and local regulations
Contaminated Packaging: Rinse thoroughly before recycling or reconditioning, otherwise treat packaging as chemical waste
Recommended Practices: Do not discharge to sewer or surface water, minimize dust during handling and transfer
UN Number: Not regulated for transport under UN Model Regulation
