Arsenic Trioxide

Arsenic Trioxide (As2O3) is a chemical taking the form of white or transparent, glassy amorphous lumps or crystalline powder. It is corrosive in the presence of moisture and toxic by ingestion. Even though it is not flammable, we still recommend a secure chemical storage building or container that meets specific regulations for storing Arsenic Trioxide. That’s why we suggest one of the following: SUPERLoc, CHEMLoc, DRUMLoc
