    . CET



    III, dust-proof explosion

    CET



    precautions:

    CET



    1, effective ventilation and dust removal, open fire is prohibited.

    . CET



    2, set up a pressure relief flap in the equipment housing, the use of explosion containment system.

    . CET



    3, the plant at risk of dust explosion should be designed in accordance with the explosion-proof technical level, and the ventilation and dust removal system should be designed separately.
