Inhalation: Move the affected person to fresh air. Symptoms are unlikely but persistent respiratory discomfort warrants medical attention
Skin Contact: Remove contaminated clothing, wash skin with water and mild soap. If irritation persists, seek medical guidance
Eye Contact: Rinse cautiously with water for several minutes holding eyelids open. Remove contacts if present and easy to do. Continue rinsing. Seek medical assistance if irritation continues
Ingestion: Rinse mouth thoroughly. Drink water to dilute product if swallowed in small amounts. Do not induce vomiting unless directed by medical professionals. Seek medical attention in the case of large quantity ingestion
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, foam, or water spray
Unsuitable Media: Do not use water jet as it may spread the material
Hazards Arising from Combustion: Burning may produce carbon monoxide, carbon dioxide, and minor organic compounds
Special Protective Equipment and Precautions for Firefighters: Wear full protective clothing including self-contained breathing apparatus. Keep containers cool with water if exposed to fire
Personal Precautions: Isolate spill area, ventilate the space, keep unnecessary people away. Use gloves and protective eyewear
Environmental Precautions: Prevent entry into waterways and drains. Contain spill for cleanup
Methods for Cleanup: Scoop up spilled material mechanically, absorb any residues with earth or inert absorbent. Waste should be collected and stored in containers for disposal
Handling: Handle with care, avoid direct contact with skin and eyes. Use only in well-ventilated areas. Maintain good industrial hygiene, such as washing hands before eating or using the restroom
Storage: Store in original, tightly closed container away from heat, moisture, and strong oxidizing agents. Keep storage area cool and dry. Prevent contamination from food or drink
