04 · Handling and storage
Storing and handling Zinc Phosphide
Storage conditions
Keep container tightly closed in a dry and well-ventilated place. Never allow product to get in contact with water during storage. Do not store near acids. Keep in a dry place. Storage class (TRGS 510): Hazardous materials, which set free flammable gases upon contact with water.
Source: Hazardous Substances Data Bank (HSDB)
Incompatible materials
Incompatible materials: Strong oxidizing agents. Keep away from water. Bases, acids.

Reactivity
ZINC PHOSPHIDE is a reducing agent. They slowly generate flammable or noxious gases in contact with water. Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides also can react vigorously with oxidizing materials. In general, materials in this group are incompatible with oxidizers such as atmospheric oxygen. They are violently incompatible with acids, particularly oxidizing acids.
