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.
  • Ensure good laboratory hygiene practices are followed.
  • Use appropriate PPE such as lab coat, compatible chemical-resistant gloves, and eye protection (safety goggles).
  • Wear respiratory protection if ventilation is inadequate or exposure limits are exceeded.
  • Ensure local exhaust ventilation is adequate to maintain airborne concentrations below occupational exposure limits.
  • Wash hands thoroughly after handling and before eating, drinking, or smoking.

First Aid / Accidental Release

  • In case of inhalation, move to fresh air. Seek medical attention if symptoms persist.
  • For skin contact, wash with plenty of soap and water. Remove contaminated clothing.
  • For 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.
  • Seek medical attention according to institutional procedures if irritation or symptoms persist.
  • Avoid dust or aerosol generation.
  • Ensure adequate ventilation during cleanup.
  • Wear appropriate personal protective equipment, including respiratory protection if needed.
  • Collect spilled material using trained laboratory procedures.

Firefighting / Stability

  • Use dry chemical, carbon dioxide, water spray, or alcohol-resistant foam for extinguishing.
  • Wear self-contained breathing apparatus and full protective gear for firefighting if necessary.
  • Evacuate personnel to a safe area.
  • Keep containers cool with water spray to prevent rupture.
  • Stable under recommended storage conditions.
  • Avoid strong oxidizing agents.
  • May react with incompatible materials.
  • No known hazardous decomposition products under normal conditions of storage and use.
