First Aid Measures

Eye Contact: Rinse immediately with water for several minutes, remove contact lenses, continue rinsing if irritation persists, seek medical advice if necessary
Skin Contact: Wash skin with soap and water, remove contaminated clothing, rinse with water, seek medical attention if irritation develops
Inhalation: Move person to fresh air, provide oxygen or artificial respiration if breathing is difficult
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical assistance for large quantities
Immediate Medical Attention: Not normally required; observe for symptoms and treat accordingly

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, Alcohol-resistant foam, Dry chemical powder, Carbon dioxide
Specific Hazards: Combustion generates carbon monoxide and carbon dioxide, vapors may form explosive mixtures with air at elevated temperatures
Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus
Special Procedures: Cool fire-exposed containers with water spray, prevent runoff from entering watercourses

Accidental Release Measures

Personal Precautions: Wear protective gloves and goggles, avoid breathing vapors, ventilate area
Environmental Precautions: Prevent entry into waterways, drains, or soil, contain spill with sand or earth
Methods for Clean-Up: Absorb with inert material, transfer to suitable container for disposal, wash area with water to remove residues

Handling and Storage

Precautions for Safe Handling: Handle in well-ventilated space, use personal protective equipment, avoid eye and skin contact, wash thoroughly after use
Conditions for Safe Storage: Store in tightly closed containers, keep in cool, dry, well-ventilated place away from direct sunlight, segregate from strong oxidizers and acids
Specific End Uses: Avoid use near ignition sources or in unventilated areas

Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limits established in most jurisdictions; ACGIH TWA: 10 mg/m³ (aerosol)
Engineering Controls: General ventilation recommended, use local exhaust when processing at elevated temperatures
Personal Protection: Protective gloves (nitrile or neoprene), safety glasses or goggles, appropriate clothing to prevent skin contact, respiratory protection when vapor or aerosol generation is likely
Hygiene Measures: Wash hands and face after handling, do not eat or drink while using, change contaminated clothing
