Get down to work just in case

On the morning of May 4, two workers of Zhongshan Public Utility Co., Ltd. had a "biogas poisoning" while carrying out underground operations on Changzhou Road in the Western District. One person died on the spot and one person was unconsciously admitted to the hospital. After the accident, the City Safety Supervision Bureau established an accident investigation team. The preliminary judgment of the responsible person of the company involved is an accident.

Before this incident, incidents of “biogas poisoning” caused by underground deaths were frequently reported. On September 25, 2011, at the construction site of the Nanjing Chengdong Sewage Treatment Plant near Ningdan Road in Yuhuatai District, Nanjing, three workers encountered three cases of unsolved gas falling down when troubleshooting the downhole water pump. Died. On November 8, 2006, three workers in Shanghai engaged in downhole operations at Aibo Road, Gaopu Road, Pudong New Area. Due to the lack of necessary protective facilities, they died after a downhole coma and died of biogas poisoning. There are still many such cases. Mr. Feng, who is in charge of Zhongshan Public Utilities Co., Ltd., said: “When Guangzhou was doing the rain and sewage diversion project, some workers died because of the poisoning of methane.”

Why is it that underground operations "methane poisoning" is still fatal? Mr. Feng explained that “the workers will wear gas masks under the old pipelines, but the pipeline in this incident was built before and after the Spring Festival. It is reasonable to say that there would be no biogas, so the workers did not wear gas masks .”

However, the underground pipe network is old and intricate. In order to protect the safety of workers going down, Nandu reporters suggested that workers should go down and use gas masks just in case.
