Storage

Preserve in a tightly closed, approved cylinder or container, protected from light and stored in a cool, well-ventilated area away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, it must be stored under an inert atmosphere (e.g., nitrogen or argon blanket). Cylinders should be secured upright. Store away from oxidizing agents, strong acids, and halogens.
