Protective Equipment: Firefighters use self-contained breathing apparatus and full protective clothing
Advice for Firefighters: Use caution for slippery surfaces formed by leaked product; water runoff may need to be contained
Personal Precautions: Evacuate non-essential personnel, ventilate area, remove ignition sources, wear chemical-resistant gloves and eye protection
Environmental Precautions: Prevent entry to sewers, ground water, or water courses; contain with non-combustible absorbent material
Cleanup Methods: Absorb with sand, earth, or inert material, transfer to labeled container for proper disposal; wash area with water to remove residue
Spill Reporting: Report to regulatory authorities if release is significant
Handling: Avoid contact with skin and eyes, do not breathe vapors, use only with adequate ventilation, wash thoroughly after handling, keep containers tightly closed
Storage: Store in cool, dry, well-ventilated area away from direct sunlight and incompatible materials such as strong acids and oxidizers, keep container upright, avoid freezing
Other Precautions: Ground/bond container and receiving equipment for bulk transfers
Occupational Exposure Limits: No official exposure limit published, use as low as reasonably practicable
