Anhai Kemuxi Downhole Drainage Three Rows of Polluters Biogas Poisoning

The rescued worker painted a sketch to explain the incident.

At 3 o'clock in the afternoon yesterday, in the sewer of a Hongxi well near the Muxi River in the vicinity of Kemu Village, Anhai Town, Jinjiang, three sewage workers were drowned by underground gas after being dredged downhole and rescued by fire brigades. Anhai Hospital was rescued. As of 7 o'clock last night, there was still one person in a coma.

Rescue: Finding trapped people 5 minutes downhole

At 5 o'clock in the afternoon yesterday, reporters rushed to the scene and three biogas poisoning personnel had been taken to the hospital. The poisoning caused by three people was a flood diverted by the Brook Creek. According to on-site fire brigade officer Xiao Zhang, due to the complex structure of the well, three fire officers and soldiers wore protective equipment, tied the safety ropes, and went deep into the narrow pipelines. After nearly five minutes of search, they were finally identified at the bottom of the well. The specific position of the trapped person, at this time, except one relatively awake, the other two are in a coma.

“At that time, the air breathing apparatus on which the rescue crew was carrying had reached an alarm state.” Xiao Zhang said that after determining the specific location, rescue workers used a belt to bind the trapped person to himself. “The people above are pulling first, and the people below are pushing... ..." Through continuous pulling, pushing and crawling, three trapped people were rescued from the well.

The witness, Mr. Chen, said that three people had been rescued. They wore raincoats and had mud on their faces. One person recovered consciousness after two or three minutes. The other two were in a coma and were then carried away by 120.

Tells: "The biogas is bigger below."

In the emergency department of Anhai Hospital, the reporter saw the rescued worker Wang Youhua. At this time he was conscious and in a good spirit.

Wang Youhua told reporters that they were dispatched to start the dredging operation of the flood diversion channel at 1:30 in the afternoon. When they went down, 3 per capita were fully armed and put on gas masks.

"Suddenly, I heard that the worker shouted for help in the bottom of the well and went on to find that the gas inside was very large." Wang Youhua said that when he was outside the well, he heard the worker's beep for help and he immediately went down to check and found that the methane in the well was large. The two workers have already lost their consciousness. He tried to rescue him, but when he just got down to the well, he felt powerless and climbed to the well for help.

Wang Youhua said that it was very likely that when the workers used water guns to open the silt, they were trapped by the methane gas that had accumulated in the mud. The two workers were poisoned and sent to the emergency department and soon they were transferred to the intensive care unit.

Hospital: One person still not out of danger

At 6:15 pm yesterday, the reporter learned from Anhai Hospital that three poisoned patients were middle-aged. Among them, one surnamed Dai was in a coma and was not out of danger. The other surnamed Lu had already had a brain. Sober, but the airway and lungs are damaged.

According to the person in charge of the intensive care unit of Anhai Hospital, the severity of the damage of two critically ill patients has not yet been judged. Now, only the symptomatic treatment can be performed to ensure the stability of each organ function of the patient.

The person in charge also revealed that the hospital examination revealed that the gas inhaled by the patient contained components such as hydrogen sulfide and ammonium hydroxide, and both critically ill patients had symptoms of hypoxic-ischemic encephalopathy.

China Labor Insurance Network Xiaobian tips:

    When operating in a confined environment, the choice of gas masks is a dangerous behavior when the oxygen content and the type of toxic gas are uncertain. Gas masks are respiratory protection products that are used only when there is sufficient oxygen in the air and the type of toxic gas in the air can be filtered out by the filter cartridge. Like this incident, Xiao Bian suggested choosing a powered air tube respirator. If it is closer to the air source, a long tube respirator can be selected.
