Signal Word: Danger

Handling and Storage
Storage Conditions:

• Store in tightly sealed containers under an inert atmosphere (e.g., nitrogen).

• Keep in a cool, dry, and well-ventilated area away from sources of ignition, strong oxidizing agents, and acids.

• Recommended storage temperature: below 25°C.

Handling Precautions:

• Use explosion-proof ventilation systems and proper PPE, including respirators where necessary.

• Work in a chemical fume hood due to its toxicity and high volatility.
