Handling & PPE

  • Handle in a well-ventilated area or under a fume hood.
  • Avoid contact with skin, eyes, and clothing.
  • Keep container tightly closed in a dry and well-ventilated place.
  • Store away from incompatible materials.
  • Wear safety glasses with side-shields or chemical safety goggles.
  • Wear chemical-resistant gloves (e.g., nitrile or neoprene) and a lab coat.
  • Use respiratory protection if ventilation is inadequate or if dust/aerosol is generated.
  • Ensure eyewash stations and safety showers are available in the workplace.
  • Dispose of contents and container in accordance with local, regional, national, and international regulations.

First Aid / Accidental Release

  • If on skin, wash with plenty of soap and water.
  • If in eyes, rinse cautiously with water for several minutes, removing contact lenses if present.
  • If inhaled, remove person to fresh air and keep comfortable for breathing.
  • If swallowed, rinse mouth and seek medical attention if symptoms occur.
  • Consult a physician if irritation persists or symptoms develop.
  • Ensure adequate ventilation and wear appropriate personal protective equipment.
  • Avoid dust or aerosol generation during cleanup procedures.
  • Prevent further leakage or spillage if safe to do so.
  • Collect spilled material using an inert absorbent and place in a suitable disposal container.

Firefighting / Stability

  • Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide for extinction.
  • Wear self-contained breathing apparatus for firefighting if necessary.
  • Cool unopened containers with water spray to prevent pressure build-up.
  • Avoid inhalation of combustion products.
  • Stable under recommended storage conditions.
  • Avoid strong oxidizing agents and strong bases.
  • May react with certain metals or strong acids.
  • Hazardous decomposition products may include carbon oxides and hydrogen fluoride.
