Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present and easy to do; continue rinsing until irritation subsides
Ingestion: Rinse mouth with water; do not induce vomiting unless directed by medical personnel; seek medical advice if large amounts are swallowed
Most Important Symptoms and Effects: Mild irritation to eyes, skin, or respiratory system in sensitive individuals
Immediate Medical Attention: Medical attention is rarely required in routine exposure scenarios
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide extinguishers
Unsuitable Extinguishing Media: High-pressure water streams have limited use
Specific Hazards Arising From the Chemical: Decomposition releases carbon monoxide, carbon dioxide, and irritating fumes
Protective Equipment for Firefighters: Full protective clothing including self-contained breathing apparatus
Firefighting Procedures: Use water spray to cool containers exposed to fire; prevent runoff to sewers and waterways
Combustion Products: Carbon oxides, possible acetic acid vapors
Personal Precautions: Use proper protective equipment to prevent eye and skin contact; ensure adequate ventilation
Environmental Precautions: Prevent release to the environment; avoid uncontrolled entry into waterways and drains
Methods for Cleaning Up: Absorb spilled material with inert absorbent (sand, earth, vermiculite); shovel into container for proper disposal; wash spill area with detergent and water and ventilate
Emergency Procedures: Evacuate non-essential personnel from area; contain and control large spills with barriers
Precautions for Safe Handling: Avoid skin and eye contact; handle in accordance with good industrial hygiene and safety practices; use with adequate ventilation
