An alarm sounded, the enterprise quickly started the device warning, and the chemical industry emergency response center immediately launched the rescue cooperation of the park. The fire-fighting high-spray car rushed to the scene to reinforce and control the disaster. The police used the helicopter to rescue the wounded, and the professional technicians carried out the pressure blockage. Leakage, unmanned aerial vehicle exploration and detection... Yesterday, the city’s large-scale petrochemical plant fire fighting and rescue comprehensive exercise, which has participated in the most teams and the most complete special equipment, has begun.

At 15:30, the chemical equipment of Shanghai Chlor-Alkali Chemical Co., Ltd., located at No. 4747 Longwu Road, leaked vinyl chloride and quickly mixed with air to form a large amount of explosive mixed gas, which caused many operators to coma...

After analyzing and judging the disaster situation, technicians and full-time fire brigade commanders decisively decided to dilute the concentration of flammable and explosive gases to prevent the leakage gas from accumulating to prevent the concentration from reaching the explosion limit.

The inspection team used the instrument to determine the concentration of the leaking gas, and the rescue team rescued the operators who were poisoned and comatose. On-site cokeed full-time firefighters wearing gray chemical protective suits, under the cover of water guns, carry the plugging device to the second floor platform to close the valve.
