04 Handling Methods and Precautions
  • When Handling

    Wear proper protective device when handling the materials.

    Use in a well ventilated place.

    Use explosion-proof equipment and prevent static electricity from occurring.

    Install a local exhaust system in the handling area.

  • Storage Instructions

    Store it separately from strong oxidizers and peroxide.

    Avoid direct sunlight and store in a cool and ventilated, non-flammable place.

    Keep the temperature below 35°C.

    Keep it isolated from other stored materials.

    When storing in a sealed container,
    install a drainage path around the storage area and block the final exit of the drain,
    to reduce the leakage range of the chemicals in case of leaking.

    Take care to protect the container against any leakage, rust, or damage.
