In order to ensure the safety of underground pipeline dredging operation, relevant units should take the following safety measures:
Only by sorting out the above safety knowledge of Chengdu's innovative pipeline dredging, can we gain some benefits in pipeline dredging. I believe we can do better in dredging pipelines.
Underground pipelines are temporarily semi-closed, and I believe many friends know that. Lack of air, less oxygen. Therefore, even if there are flammable and explosive gases underground, there will be no combustion and explosion. But when the lid is opened, flammable and explosive gases mix with air to form explosive gases. At this time, if the pipeline is maintained and welded, there will be the risk of combustion and explosion. Chengdu innovative dredging pipeline reminds: carbon dioxide or nitrogen must be replaced before operation. Considering that the above two gases are inert gases, after replacement, in order to prevent the occurrence of poisoning accidents in underground operation, ventilation must be carried out before operation. Natural ventilation and forced ventilation are available. In general, natural ventilation is sufficient for the inspection of underground pipelines. The manhole cover nearby must be opened and ventilated for at least one hour. Under special circumstances, forced ventilation should be used before the pipeline is dredged. The fan can be connected with the duct to sweep the air under the pipeline.

In order to prevent the occurrence of acute poisoning accidents and to ensure the safety of underground pipeline dredging operation, relevant units shall take the following safety measures:
But there are still some unsafe factors that cannot be ruled out. Wearing all kinds of protective articles according to regulations can prevent these dangerous factors from harming people. In operation, active measures are sometimes taken to dredge underground pipelines. The most important thing is to wear gas mask correctly to prevent poisoning. As mentioned earlier, once the sewage pipeline is open, the accumulated hydrogen sulfide, methane and carbon monoxide gas in the pipeline will suddenly flow out of the well. At this time, the gas concentration is very high, so long tube masks, oxygen respirators and other isolation gas masks must be worn. Especially when workers are found poisoned, rescuers should wear isolation gas masks for rescue. Never forget to wear gas masks or filter masks, because you are eager to save others. As a result, rescue workers were also injured, and the casualties and losses caused by poisoning accidents increased. Welcome to call Guangzhou dredging company, dredge sewers, dredge pipelines, high quality and reasonable charges.
