Chemical Name: Melamine Cyanurate
CAS Number: 37640-57-6
Percentage (w/w): 65–75%
Other Components: Polyolefin or polyamide carrier resin (balance)
Impurities: Trace unreacted melamine, cyanuric acid, less than 1%
Additives: Processing aids or lubricants below 2% (proprietary, non-hazardous)
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes; remove contact lenses if present and safe to do so; seek medical help if irritation persists
Skin Contact: Wash skin with soap and water; remove contaminated clothing and footwear; prolonged contact is not harmful, but persistent irritation should be evaluated by a doctor
Inhalation: Move person to fresh air; keep at rest in a position comfortable for breathing; obtain medical attention if symptoms persist such as coughing or wheezing
Ingestion: Rinse mouth with water thoroughly; do not induce vomiting; obtain medical advice
Most Important Symptoms: Eye and airway discomfort; red, itchy skin
Notes to Physician: Treat symptomatically based on patient’s condition and route of exposure
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide
Unsuitable Media: Direct high-pressure water jets can scatter dust
Specific Hazards: Product decomposes at high temperature to produce nitrogen oxides, ammonia, carbon monoxide, and cyanuric gasses
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear
Special Precautions: Avoid breathing smoke; contain runoff water to avoid environmental contamination; evacuate non-essential people from the area
Personal Precautions: Avoid dust generation; use respirators and goggles in case of massive dust; keep unprotected persons away
Environmental Measures: Prevent material from entering drains or water sources; sweep up spills promptly
Methods for Cleanup: Use antistatic tools and containers; collect mechanically, avoid creating airborne dust; place in suitable labeled containers for disposal
Decontamination: Wash affected area with water after removal of solid material
Handling Precautions: Use with effective ventilation; minimize dust formation; avoid contact with eyes, skin, and clothing; wear protective equipment; handle in accordance with good industrial hygiene
Safe Storage Conditions: Store in tightly closed containers; keep in dry, cool, well-ventilated area; avoid exposure to heat, flame, and strong oxidizers; prevent build-up of dust on surfaces
Incompatible Materials: Strong acids, oxidizers, bases, or materials that might release heat on contact
Occupational Exposure Limits: No specific OSHA or ACGIH limits for melamine cyanurate; use total or respirable dust limits as guidance (e.g., OSHA PEL: 15 mg/m³ total dust; 5 mg/m³ respirable)
Engineering Controls: Provide local exhaust ventilation; isolate sensitive operations
Eye Protection: Safety glasses with side shields; goggles during bulk, dusty handling
Hand Protection: Protective gloves; nitrile or PVC recommended
Skin Protection: Work clothing covering arms, legs, and feet
Respiratory Protection: NIOSH-approved dust mask or respirator if dust levels are excessive
