Handling & PPE

  • Handle in a well-ventilated area or fume hood.
  • Avoid inhalation, ingestion, and skin/eye contact.
  • Keep container tightly closed in a dry and well-ventilated place.
  • Store away from incompatible materials.
  • Use appropriate PPE such as lab coat, compatible gloves, and eye protection.
  • Wear chemical-resistant gloves.
  • Wear safety glasses or face shield.
  • Use respiratory protection if ventilation is inadequate or if dust/aerosol is generated.
  • Dispose through approved chemical waste channels according to local and institutional regulations.

First Aid / Accidental Release

  • In case of inhalation, move to fresh air. Seek medical attention if irritation persists.
  • For skin contact, wash thoroughly with soap and water. Remove contaminated clothing.
  • In case of eye contact, rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
  • If swallowed, rinse mouth. Do NOT induce vomiting. Seek medical attention.
  • Avoid dust or aerosol generation.
  • Ensure adequate ventilation during cleanup.
  • Wear appropriate personal protective equipment.
  • Collect spilled material using trained-lab procedures and place in a suitable container for disposal.
  • Prevent further leakage or spillage if safe to do so.

Firefighting / Stability

  • Use extinguishing media appropriate for the surrounding fire.
  • Wear self-contained breathing apparatus and full protective gear for fire fighting.
  • Prevent fire-fighting water from entering drainage systems or water courses.
  • May emit toxic fumes under fire conditions.
  • Stable under recommended storage conditions.
  • Avoid strong oxidizing agents.
  • May decompose under fire conditions, emitting hazardous fumes.
  • No known hazardous reactions under normal conditions of use.
