    Transportation Precautions:

    During railway transportation, the dangerous goods loading table in the "Dangerous Goods Transportation Rules" of the Ministry of Railways should be strictly followed. Before transportation, check whether the packaging container is complete and sealed. During transportation, ensure that the container does not leak, collapse, fall, or be damaged. It is strictly forbidden to mix with acids, oxidants, food and food additives. During transportation, it should be protected from exposure to sunlight, rain, and high temperature.

    Storage Precautions:

    Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The packaging must be sealed and cannot come into contact with air. It should be stored separately from oxidants, acids, alkalis, and edible chemicals, and must not be mixed. Equipped with fire equipment of corresponding types and quantities. The storage area should have appropriate materials to contain leaks. The "five pairs" management system for extremely toxic items should be strictly implemented.

    Packing Precautions:

    Plastic bags or double-layer kraft paper bags outside fiberboard barrels, plywood barrels, cardboard barrels; plastic bags or double-layer kraft paper bags outside ordinary wooden boxes; threaded glass bottles, iron-capped glass bottles, plastic bottles or metal barrels (cans) outside ordinary wooden boxes; threaded glass bottles, plastic bottles or tinned thin steel barrels (cans) outside full-bottom lattice boxes, fiberboard boxes or plywood boxes.
