Firefighting Instructions: Use self-contained breathing apparatus, wear full protective gear, cool exposed containers with water spray
Advice for Firefighters: Prevent runoff from entering waterways, contain fire water
Personal Precautions: Wear suitable protective equipment, ventilate the area well, avoid inhaling vapors
Environmental Precautions: Prevent further leakage or spillage if safe to do so, block entry to waterways or drains
Methods for Containment and Clean Up: Absorb with inert material (sand, earth), collect in chemical waste container, dispose of according to local regulations, decontaminate area with detergent and water
Handling: Handle in a well-ventilated area, avoid contact with skin and eyes, avoid inhalation, use proper personal protection
Storage: Store in a cool, dry, well-ventilated area, keep container tightly closed, segregate from acids, bases, strong oxidizers and reducing agents, protect from direct sunlight
Incompatible Materials: Strong acids, strong bases, strong oxidizing agents
Engineering Controls: Work in local exhaust ventilation or fume hood, maintain eyewash stations and emergency showers
Personal Protective Equipment: Chemical-resistant gloves (e.g. nitrile), safety goggles or full-face shield, lab coats or impervious clothing, appropriate respiratory protection for vapor/mist exposure
Exposure Limits: No OSHA or ACGIH exposure limit established, minimize exposure as low as reasonably achievable
