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, such as strong oxidizing agents.
  • Wash hands thoroughly after handling this material.
  • Wear a lab coat or other protective clothing.
  • Wear compatible protective gloves (e.g., nitrile or neoprene).
  • Wear eye protection such as safety goggles or a face shield.
  • Use respiratory protection if ventilation is inadequate or if dust/aerosol is generated.

First Aid / Accidental Release

  • In case of skin contact, wash with plenty of soap and water.
  • In case of eye contact, rinse thoroughly with water for several minutes, removing contact lenses if present and easy to do.
  • If inhaled, move to fresh air and keep comfortable for breathing.
  • If swallowed, rinse mouth with water and do not induce vomiting.
  • Seek medical attention if irritation persists or symptoms develop.
  • Avoid dust formation and breathing vapors or dust.
  • Ensure adequate ventilation during cleanup.
  • Wear appropriate personal protective equipment, including gloves and eye protection.
  • Sweep up or scoop spilled material into suitable containers for disposal.

Firefighting / Stability

  • Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide for extinction.
  • Wear self-contained breathing apparatus and full protective gear for firefighting if necessary.
  • Keep containers cool with water spray to prevent rupture.
  • Prevent runoff from fire control from entering waterways or sewers.
  • Stable under recommended storage conditions.
  • May react with strong oxidizing agents.
  • Avoid strong acids and strong bases.
  • Avoid elevated temperatures and direct sunlight to maintain product integrity.
