BARIUM MOLYBDENUM OXIDE - Safety
Open Data Verified Data
packed with fiber barrels lined with clean polyethylene plastic bags. 40kg net weight per barrel. Care should be taken to prevent cracks in the mouth of the plastic bag. The package should be marked with "drug. Store in a ventilated and dry warehouse. In case of humid air, the powder is easy to absorb moisture and must be sieved. Tie the mouth of the bag tightly or cover tightly to avoid adhesion. It is not allowed to be stored and mixed with edible articles. Transport should be protected from rain and sun exposure. When loading and unloading should be light to prevent packaging damage. In case of fire, it can be suppressed by water, sand and all kinds of fire extinguishing. Toxicity and protection see Molybdenum trioxide.
