First Aid Measures

General: Seek fresh air. Remove contaminated clothing.
Inhalation: Move to a well-ventilated area. If symptoms persist, call a physician.
Skin Contact: Wash thoroughly with plenty of soap and water. Remove contaminated clothing and shoes.
Eye Contact: Rinse gently with plenty of water for at least 15 minutes. Remove contact lenses if present.
Ingestion: Rinse mouth. Call poison control or physician immediately if feeling unwell. Do not induce vomiting unless instructed.

Fire-Fighting Measures

Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water fog
Unsuitable Media: Direct water jet, which can spread the fire
Special Hazards: Emits hazardous vapors or toxic fumes under fire conditions, including oxides of carbon and silicon
Protective Equipment for Firefighters: Full-body protective suit and self-contained breathing apparatus
Specific Methods: Use water spray to cool containers. Contain runoff, prevent entry into drains or waterways.

Accidental Release Measures

Personal Precautions: Evacuate area of non-essential personnel. Avoid inhalation and direct contact.
Protective Equipment: Chemical-resistant gloves, safety goggles, respirator when ventilation inadequate
Environmental Precautions: Prevent further leakage, spill, or entry to water sources or soil
Clean-Up Methods: Absorb with inert absorbent material (sand, earth, diatomite). Sweep or scrape up and collect for disposal. Ventilate area and wash residual contamination with detergent and water.

Handling and Storage

Handling: Avoid direct contact with skin, eyes, and clothing. Work only in well-ventilated areas. Do not breathe vapors or mists. Wash hands thoroughly after handling.
Storage: Store in original tightly-closed containers. Keep in a dry, cool, and well-ventilated space. Keep away from sources of ignition, strong oxidizers, acids, and bases. Store locked up and secure from unauthorized access.
