Inhalation: Move affected person into fresh air immediately; if breathing trouble occurs, seek medical attention
Skin Contact: Wash with plenty of water and mild soap; if irritation develops, consult a healthcare provider
Eye Contact: Flush eyes with water several minutes, lifting upper and lower lids; remove contact lenses if present and easy to do; seek medical attention for persistent discomfort
Ingestion: Rinse mouth, never induce vomiting unless directed by medical personnel; consult a doctor if symptoms appear
Most Important Symptoms: Mild irritation, redness, or discomfort at site of exposure
Special Advice to Responders: Wear standard personal protective equipment during response; avoid breathing dust
Suitable Extinguishing Agents: Water spray, dry chemical, CO2, foam
Specific Hazards: Combustion may produce irritating fumes such as carbon oxides and sodium oxides
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing
Special Procedures: Avoid inhalation of any combustion products, cool containers with water if exposed to fire
Unusual Fire Hazards: Not known to present explosion or unique combustion risks in solid form
Personal Precautions: Avoid creating dust, ventilate area well, limit exposure to spill area with proper PPE such as gloves, goggles, and mask
Environmental Precautions: Do not allow product to reach sewage system, surface or groundwater
Methods for Clean-Up: Scoop or sweep up material and transfer to appropriate containers for disposal; wash area with plenty of water to remove residues
Emergency Procedures: Contact authorities if contaminated waterway or significant release occurs; notify supervisors in workplace settings
Handling: Use in well-ventilated environments, minimize dust generation, avoid contact with eyes, skin, or clothing, keep away from food and animal feed
Storage: Keep container tightly closed in dry, cool conditions, away from direct sunlight; recommend storage below 25°C; store in original packaging
