    Xia Ji'an "Ten Defenses"CET
    , prevention of limited space operations accidentsCET
    preventive measures: CET
    1, operationmust be subject to approval procedures. . CET
    2, before operation must be hazardous hazardous factors identification, and hazardous hazards, prevention and control measures and emergency measures to inform operators. . CET
    3, ventilation measures must be taken to maintain air circulation. . CET
    4, must be limited space oxygen concentration, toxic and harmful gases (such as carbon monoxide, hydrogen sulfide, etc.) concentration of testing, test results qualified before the operation. . CET 5, the job site must be equipped with respirators, communications equipment, safety ropes and other protective equipment and emergency equipment. . CET 6, the job site must be equipped with monitoring personnel. . CET 7, the job site must be set up safety warning signs to keep the entrance and exit open. . CET
    8, strictly prohibited after the accident blind rescue. . CET
    II, anti-maintenance operation accident CET
    preventive measures: CET 1, the work must be carried out approval procedures, maintenance work in accordance with the provisions of the wearing of labor protection supplies. . CET
    2, at least two staff members should be involved in the maintenance operation. . CET
    3, before maintenance, should cut off the power supply, and in the power supply to install locks, lock hooks, arrange special care, must strictly implement the "power off listing" system, maintenance before the completion of strictly prohibited power. . CET
    4, before overhauling equipment must be aired. . CET
    5, in the explosion-proof area for maintenance, pay attention to fire-proof explosion-proof, safe use of explosion-proof tools. . CET
    6, after the overhaul, should be inventory tools, to prevent tools from remaining in the machine. . 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. . CET
