济南管道疏通告诉你一定要记住这些安全知识!

  下水道和日常管道长期处于关闭或半关闭状态,缺少空气,就不会与氧气接触,即使地下有易燃易爆气体,也不会发生燃烧爆炸现象。但当盖子打开时,易燃易爆气体与空气混合形成爆炸性气体。此时,如果对管道进行维护和焊接作业,就会有燃烧和爆炸的危险。因此,在操作前必须更换二氧化碳或氮气。考虑到以上两种气体均为惰性气体,更换后,为了防止井下作业中毒事故的发生,必须在作业前进行通风。

  Sewerage and daily pipelines are closed or semi-closed for a long time. Without air, they will not contact with oxygen. 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. Therefore, 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.

  有自然通风和强制通风。一般情况下,对地下管道的检查,自然通风就足够了。附近必须打开3 ~ 4个井盖,通风时间至少为1小时。特殊情况下,管道疏通前必须采用强制通风,风机可与风道连接,进行风箱送风。

  Natural ventilation and forced ventilation are available. In general, natural ventilation is sufficient for the inspection of underground pipelines. Three to four well covers must be opened nearby for at least one hour of ventilation. Under special circumstances, forced ventilation must be used before the pipeline is dredged. The fan can be connected with the air duct to supply air in the bellows.

  虽然在地下管道疏通方面采取了一些积极措施,但仍存在一些不安全因素。按照规定穿戴各种防护用品,可以避免这些危险因素对人的危害。在操作中,主要是正确佩戴防毒面具,以防中毒。
  Although some positive measures have been taken to dredge underground pipelines, there are still some unsafe factors. Wearing various protective articles according to regulations can avoid the harm of these dangerous factors to human beings. In operation, the main thing is to wear gas mask correctly to prevent poisoning.

  如前所述,一旦污水管道畅通,管道中积聚的硫化氢、甲烷和一氧化碳气体会突然从井中涌出。此时气体浓度非常高,必须佩戴长管口罩、氧气呼吸器等隔离式防毒面具。特别是当发现工作人员中毒时,救援人员应戴好隔离式防毒面具进行抢救。永远不要忘记戴防毒面具或只戴过滤防毒面具,因为你渴望拯救他人。结果,救援人员也受伤了,中毒事故造成的伤亡和损失增加了。
  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.
