First Aid Measures

Eye Contact: Flush with plenty of water for at least 15 minutes, remove contact lenses, seek medical attention if irritation continues
Skin Contact: Remove contaminated clothing, wash skin with soap and water, seek medical attention for persistent irritation
Inhalation: Move to fresh air, keep at rest in a position comfortable for breathing, get medical attention if symptoms develop
Ingestion: Rinse mouth, drink water, do not induce vomiting, get medical attention if symptoms appear
Most Important Symptoms: May cause mechanical irritation to eyes and respiratory tract
Notes for Physician: Treat symptomatically

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Extinguishing Media: Direct water jets (risk of dust dispersal)
Fire Hazards: Low fire hazard, but thermal decomposition can release toxic gases including nitrogen oxides, ammonia, cyanuric acid
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing
Specific Methods: Avoid breathing combustion products, cool containers exposed to fire with water spray

Accidental Release Measures

Personal Precautions: Use protective clothing, gloves, eye protection, dust mask where dust may be generated
Environmental Precautions: Prevent spillage from entering drains, sewers, or surface waters
Containment Methods: Sweep up and shovel spilled material into suitable containers for disposal, avoid creating dust clouds
Clean-up Procedures: Wash spill area with water after clean-up, ventilate closed areas

Handling and Storage

Handling: Use only in well-ventilated areas, minimize dust formation and accumulation, avoid contact with skin and eyes, avoid inhaling dust
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing before eating, drinking, or smoking
Storage Requirements: Store in a cool, dry, well-ventilated place, keep containers tightly closed, protect from moisture and direct sunlight
Incompatible Materials: Strong oxidizers, strong acids

Exposure Controls and Personal Protection

Occupational Exposure Limit: No established TLV or PEL for melamine
Engineering Controls: Use local exhaust ventilation or general dilution ventilation to control airborne dust
Respiratory Protection: Wear an approved particulate respirator when handling large quantities or in dusty conditions
Skin Protection: Wear protective gloves (nitrile recommended), long-sleeved clothing
Eye Protection: Safety goggles or glasses with side shields
Other Protective Measures: Provide eye wash facilities and safety showers at the workplace
