Inhalation: Move person to fresh air. Rest in a position comfortable for breathing. If breathing difficulty persists, seek medical attention.
Skin Contact: Remove contaminated clothing and rinse skin thoroughly with soap and water.
Eye Contact: Rinse immediately with clean water for several minutes, holding eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. Get medical attention if irritation remains.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Seek immediate medical help.
Most Important Symptoms: Drowsiness, dizziness, eye irritation, skin dry-out or cracking.
Medical Attention: Provide detailed information about the substance if professional help arrives.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam, water spray.
Unsuitable Media: High pressure water jets may spread the fire.
Specific Hazards: Vapors may travel and ignite at distant points. Closed containers may rupture from fire exposure.
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, acrid fumes.
Protective Equipment: Wear self-contained breathing apparatus and full protective gear.
Firefighting Procedures: Stop leak if safe to do. Cool containers with water spray even after fire is out to prevent re-ignition or rupture.
Personal Precautions: Keep unprotected people away; ventilate area. Avoid breathing vapors. Wear proper protective clothing, gloves, and goggles.
Environmental Precautions: Prevent further leakage if safe to do. Do not let product enter drains, rivers, or soil.
Methods for Cleanup: Stop source of leak. Absorb with non-combustible material like sand, earth, or vermiculite. Use spark-proof tools. Collect residue in labeled containers for disposal.
Decontamination: Wipe clean contaminated surfaces with suitable solvents compatible with equipment and environment.
Handling: Use only outdoors or in well-ventilated spaces. Ground and bond containers when transferring liquid. Avoid prolonged or repeated skin contact. Avoid breathing mist or vapor.
Storage: Keep in tightly closed original container. Store in cool, dry place away from sources of heat, spark, open flame. Store away from strong acids, alkalis, and oxidizing agents.
Special Precautions: Maintain working area free from unnecessary combustible materials. Use proper signage, keep containers labeled.
Incompatibilities: Do not store with acids, bases, oxidizers, or food products.
