Handling & PPE

  • Handle in a well-ventilated area or under a fume hood.
  • Avoid contact with skin, eyes, and clothing.
  • Avoid inhalation of vapor or mist.
  • Keep container tightly closed in a dry and well-ventilated place.
  • Store away from incompatible materials.
  • Wear safety glasses with side-shields.
  • Wear a laboratory coat or protective clothing.
  • Wear compatible protective gloves.
  • Use respiratory protection if ventilation is inadequate or exposure limits are exceeded.

First Aid / Accidental Release

  • If inhaled, move to fresh air. If not breathing, give artificial respiration.
  • In case of skin contact, wash off with soap and plenty of water.
  • In case of eye contact, rinse thoroughly with plenty of water for at least 15 minutes.
  • If swallowed, rinse mouth with water. Do NOT induce vomiting.
  • Seek medical attention if irritation or symptoms persist.
  • Wear appropriate personal protective equipment.
  • Avoid dust formation and prevent breathing vapors, mist, or gas.
  • Ensure adequate ventilation.
  • Prevent further leakage or spillage if safe to do so.

Firefighting / Stability

  • Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
  • Do not use a solid water stream as it may spread the fire.
  • Wear self-contained breathing apparatus for firefighting if necessary.
  • Wear full protective gear to prevent contact with skin and eyes.
  • May emit toxic fumes under fire conditions.
  • Stable under recommended storage conditions.
  • Avoid strong oxidizing agents, strong acids, and strong bases.
  • May decompose upon heating.
  • Hazardous decomposition products may include carbon oxides, nitrogen oxides, hydrogen chloride, and hydrogen fluoride.
