Storage

Preserve in a tightly closed, properly rated cylinder, protected from light and stored in a cool, well-ventilated area. Due to its highly volatile and gaseous nature, cylinders must be secured upright and stored separately from strong bases and oxidizers. Store at room temperature (15-25°C) away from heat sources and direct sunlight. The container should be kept under an inert atmosphere and checked regularly for leaks.
