First Aid Measures

General Advice: Get medical attention right away if you feel unwell or after significant contact.
Inhalation: Move person to fresh air. Keep comfortable for breathing. Seek immediate assistance if breathing has difficulty.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing. Seek medical care if irritation or burns appear.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek urgent medical help.
Ingestion: Rinse mouth. Do not induce vomiting. Drink water if conscious and alert. Call medical services promptly.

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, CO₂, foam, or water spray can put out flames. Avoid direct water streams.
Special Hazards: Sulfur oxides, carbon oxides, and unidentified toxic fumes could develop in a fire.
Fire-Fighter Protection: Full protective suit and self-contained breathing apparatus help shield responders. Always move containers from the fire area if safe.

Accidental Release Measures

Personal Precautions: Avoid inhalation and contact with skin, eyes, and clothing. Wear appropriate protective gear.
Environmental Precautions: Prevent product from entering drains, waterways, or soil.
Clean-Up Methods: Contain spill with inert materials (sand, earth). Collect in suitable, labeled containers for disposal. Ventilate the area after cleanup is complete.

Handling and Storage

Handling: Handle with chemical-resistant gloves, safety glasses, and protective clothing. Use only in ventilated areas to avoid inhalation of vapors or mists. Practice good hygiene after use. Avoid eating, drinking, or smoking when handling chemical.
Storage: Store in tightly closed containers in a dry, cool, and well-ventilated area. Keep away from incompatible substances such as strong bases, oxidizers, and strong acids. Store away from direct sunlight and sources of ignition.
