    管道疏通需求紧记的安全常识
    Safety knowledge of pipeline dredging needs
    下水道和日用管道长时刻处于封闭或半封闭的状况,短少空气,也不会与氧气触摸,即便地下有易燃易爆气体,也不会发作焚烧爆破的现象。但当井盖翻开今后,易燃易爆气体与空气混合,形成爆破性气体。此刻假如进行管道修理和焊接等作业,就会有焚烧爆破的风险。因而,在作业前先用二氧化碳或氮气进行置换。考虑以上两种气体为惰性气体,置换今后,为防止地下作业中毒事端的发作,在作业前还进行通风。
    Sewers and domestic pipelines are closed or semi-closed for a long time, short of air, will not touch with oxygen, even if there is flammable and explosive gas underground, will not occur incineration and explosion phenomenon. But when the manhole cover is turned open, inflammable and explosive gases are mixed with air to form explosive gas. At the moment, if there are pipeline repair and welding operations, there will be risk of burning and blasting. Therefore, carbon dioxide or nitrogen should be used before replacement. Considering the above two gases as inert gases, replacing the future, in order to prevent the occurrence of underground work poisoning, ventilation is also carried out before the operation.
    通风方法有自然通风和强制通风两种。一般地下管道查看采纳自然通风即可,翻开邻近3—4个井盖,通风时刻至少1小时。特别情况下,管道疏通前,还选用强制通风,可用鼓风机接上风管施行管下吹风。

    There are two kinds of ventilation methods: natural ventilation and forced ventilation. Normally underground pipeline can be checked and adopted natural ventilation, open the adjacent 3 - 4 well cover, ventilation time at least 1 hour. In particular, before the pipeline is dredged, forced ventilation is also used, and the blower can be connected with the air duct to blow under the pipeline.

    地下疏通作业中有时尽管采纳了活跃措施,但仍会有一些不安全要素无法扫除。按规则穿戴好各种防护用品就可以防止这些风险要素对人的损伤。在作业中,主要是要正确佩带防毒面具,以防中毒。
    Sometimes, although active measures are adopted in underground dredging, there are still some unsafe elements that can not be removed. Wearing all kinds of protective articles according to rules can prevent these risk factors from damaging people. In order to prevent poisoning, it is necessary to wear gas masks correctly.
    下水管道一旦被疏通开,积聚在管道的硫化氢、甲烷和一氧化碳有毒气领会俄然冲出井口。此刻毒气浓度很大,佩带长管面具、氧气呼吸器等阻隔式防毒面具。尤其当发现作业人员现已中毒时,抢救人员更应戴好阻隔式防毒面具再救人。决不能因救人心切,就忘掉戴防毒面具或只戴过滤式防毒面具。成果使施救人员也遭到损伤,清洗管道扩展中毒事端的人员伤亡和丢失。
    Once the sewer pipes are opened, the toxic gases of hydrogen sulfide, methane and carbon monoxide accumulated in the pipes rush out of the wellhead. At the moment, the concentration of poisonous gas is very large, wearing a gas mask with long tube mask and oxygen respirator. Especially when it is found that the workers have been poisoned, rescue workers should wear barrier gas mask to save people. We must not forget to wear gas masks or filter respirators because we are eager to save lives. As a result, the rescuers were also injured, and the casualties and losses of the poisoning incidents were cleaned.
