The author:(作者)qqpublished in(发表于) 2013/11/26 9:04:18 Qingdao 7 hours before the explosion： diesel fumes the city streets without the knowledge
From 22nd East yellow pipeline oil spills, to 10:30 explosion, within 7 hours, Qingdao, Sinopec and multisectoral remove danger on the ground, but nearby residents and pedestrians has not been informed of any evacuation even rescue staff and firefighters, did not receive the warning message.
Yesterday, the incident investigation team leader, Director of the State administration of safety supervision pillar Yang pointed out that this was a very serious accident. And planning layout of urban drainage pipe network of oil pipelines unreasonable; fail to fulfil the responsibility of safe production, pipeline management, resulting in an oil spill, and improper leakage after emergency treatment, fails to set the warning zone, by preventive measures such as closed roads, alerts, evacuation of personnel.
As of yesterday, this accident has led to 55 people were killed and 9 were missing, 145 people were injured.
2:40 pipeline leak
Or for coating serious aging?
22nd, Sinopec Qingdao development zone East of yellow oil pipeline ruptured and oil spills.
At 3 o'clock in the morning, some people see a flashing yellow light for vehicle speed past, wearing "Sinopec" naked people walking in the street.
Sinopec 23rd disclosed news that this explosion of yellow-East pipeline, in July 1986, was put into operation. Statistics show that original design from Dongying via city, Weifang, high density, cities and counties, Huangdao oil pipeline 248.5 km in length, diameter 711 mm, annual oil capacity of 10 million tons.
East yellow oil pipeline has served for more than 20 years, according to the Sinopec pipeline storage and transportation management information at the Weifang, in investigation of corrosion on two occasions, found the pipe "coating has serious ageing pipeline condition is worrying," the urgent need to overhaul.
In 2011, yellow oil pipeline into the reform agenda. But in September of that year an EIA announcements, rectification and faced great difficulty: as part off a building near pipeline, pipeline coating overhaul cannot be made. EIA also show reconstruction project mainly covers, Eastern Yellow double line pipeline rerouted, which include Huangdao Huangdao oil outlet line of 15-16.
But the reform plan was not implemented, Shandong environmental protection Science Research Institute and a staff member said to the media, some section of East yellow double line Project EIA work is still in progress, have been unable to commence work.
In late February, Eastern Yellow oil pipeline began major repairs, consists mainly of replacement of pipeline coating, leak testing, non-destructive testing and other EDM. As of April this year, Eastern Yellow completed overhaul of 8 km of oil pipelines. In front of the oil spill and explosion, and major repair of the wiring has been completed, is not clear.
In October this year, China held a nationwide safety inspections, this pipeline is also included in the check. This inspection scale, identify a total of 8,091. But confirmation has not been responding to, Eastern Yellow oil pipeline also identified problems, and for rectification.
Close the valve 3:15
Infiltration of civil pipe of crude oil are highly explosive
According to Sinopec informed that an oil spill more than half an hour, 3:15, Huangdao oil depot to close oil valve. But at this point, the zhaitang Island Street, about 1000 square meters have been polluted by oil. Even more important is: risk of spill of crude oil into the water pipeline. Sinopec spokesman said that crude oil from the pipeline into the municipal drainage culverts, stream for 12 minutes.
Was supposed to distance himself from construction and other pipeline pipeline in zhaitang Street area of the island is not only close to the building, and interspersed with other pipe lines.
And Qinhuangdao road intersection in zhaitang Island Street, East-West oil pipeline has completely burst, broken oil pipelines cross drainage culverts, crosses the line, floating black greasy water flowed from the pipe. Not only that, there are ten lines or close to the oil pipeline, or cross the line.
Rescue of Sinopec's engineers are at the scene confirmed that the oil pipeline from underground waterways pass through.
National Research Center for urban pollution control technology researcher Peng Yingdeng said the accident apparently buried in the underground industrial pipelines conveying Chemicals and commercial network came into conflict, if only oil pipeline, in the event of leaks, because of its special design, can be cut off very quickly one of the sections, and volatilization rapidly expose gas leakage in space, and less likely to produce an explosion.
But the accident, oil pipeline of crude oil seeped into civilian pipe of the safety factor is not so high, which is an enclosed space, "like mine is filled with gas, flames are highly explosive. "Peng Yingdeng said.
While the fire difficult to control in the pipeline. Panel members Wang Gangwei China Petroleum pipeline company said, "the car exhaust pipe and Flaming Star, workers repairing splashes sparks could trigger explosions. ”
China Petroleum and Petro-chemical equipment industry association, Zhao Zhiming of the Chief Adviser also pointed out that oil pipelines, apart from crude oil, will have some gas, the gas is flammable and explosive. Close the valve, describe the relevant personnel are lacking in experience, improper handling.
Emergency accident processing of an oil industry security experts said in an interview, once oil or chemical spill, first to take emergency measures to prevent leaks is one of the most important substances into the sewer, because leaking the material once it enters the sewers, things will become difficult to control.
5 Street filled with diesel fumes
Municipalities are always informed
5 o'clock in the morning, oil spill near the whole street has been filled "the strange smell of diesel-like."
About 5:20, the company's Deputy Director of pipeline oil transportation management company Weifang Xing Yuqing got a call from transportation movement control section, said Qingdao Huangdao oil leak and the relevant departments have rushed to the scene, Qingdao oil station in command. Xing Yuqing believes, "which means the emergency plan has been started."
According to the People's Republic of China Law on protection of oil and natural gas pipelines (hereinafter referred to as the pipelines Protection Act), and pipeline accidents, pipeline enterprises should immediately activate Enterprise pipeline accident emergency plan.
According to the 2011 regulations on emergency management of Sinopec when (China) Enterprise directly under emergency situations, such as, the unit should be within 1 hour of Sinopec's Office total duty room, security, environmental protection agency and others in charge of the Department's report, and submit the latest developments at any time.
23rd, the Qingdao Maritime Bureau Deputy Director Dong Haiyan said the Marine Department received a report, which is several hours after the accident, has delayed the best remediation time. 24th, Qingdao environmental protection Bureau Deputy Director Ning Chen said Sinopec, environmental protection departments were informed at 8 o'clock in the morning on the day of the incident spill.
And the Qingdao Municipal Government knows, not later, 23rd, said Guo Jishan, Deputy Secretary General of the Municipal Government of Qingdao, the City Government is the explosion accident only after know the spill, oil spill before they did not know.
Sinopec 22nd communication display: John 3:15 "zone, immediate disposal," oil spill, and in 7:30 set at the mouth of the two booms.
Xing Yuqing said almost at 6 o'clock in the morning on the day, Qingdao oil transfer station and call him, has begun to see the oil on the sea. Local personnel are already in the field of security and environmental protection departments.
When enterprises to inform the local government? Qingdao Municipal Government knew before the explosion? Who should notify the city? There are at present no response.
Guo Jishan recognition media, Sinopec Huangdao Government have notified after the oil spill and fire, police and other departments at the district level, but did not notify the city.
One Sinopec insiders interviewed by the media said: "we have notified (Huangdao) Government, why does the Government not to notify the city? ”
According to the law on the protection of the pipeline, pipeline accidents, pipeline enterprises shall report the accident happened to county-level people's Governments in charge of pipeline Protection Department, work safety supervision and management departments and other relevant reports. This means, the company should notify the district-level government agencies.
10:30 bang
Nearby residents have not been informed
With sky light, citizens went to work as usual in Huangdao or send their children to school.
Before and after 8:30, Xing Yuqing to the spill site, a dozen construction workers were repairing, there are social traffic through on side roads.
Xing Yuqing said he thought traffic order was a bit of a mess, you need traffic, let companies police chiefs call 110 and want to increase the police presence.
The China Petro-chemical emergency management regulations, article is insisting on the principle, the principle of harm reduction. Firmly establish the idea of safety first, and give top priority to safeguarding the lives and health of employees, the public.
The pipeline Protection Act clearly provides that pipeline accidents, pipeline enterprises shall, without delay, inform the unit and residents may be subject to accidental hazards, to take effective measures to eliminate or minimize accident hazards.
But nearby pedestrians and residents, no one received notification of withdrawal. Next to their crews and Government officials walking by. People have seen, under the already leaking pipes, flickering electric welding sparks.
Yesterday, the incident investigation team leader, Director of the State administration of safety supervision pillar Yang pointed out that this was a very serious accident: improper leakage after emergency treatment, fails to set the warning zone, by preventive measures such as closed roads, alerts, evacuation of personnel.
10:30, Qinhuangdao road, Huangdao, stormwater tunnel and pipeline repair jobs, successive conflagration.

从22日凌晨2时40分东黄输油管道原油泄漏，到10时30分爆炸发生，7小时内，中石化和青岛当地多部门参与排险，但附近居民区和行人却未获任何疏散通知；甚至抢险的企业员工和消防人员，也没接到警示信息。
昨日，事故调查组组长、国家安全监管总局局长杨栋梁指出，这是一起十分严重的责任事故。输油管道与城市排水管网规划布置不合理；安全生产责任不落实，对输油管道疏于管理，造成原油泄漏；泄漏后的应急处置不当，未按规定采取设置警戒区、封闭道路、通知疏散人员等预防性措施。
截至昨日，这次事故已导致55人死亡、9人失踪、145人受伤。
●2时40分 管道泄漏
或因防腐层严重老化？
22日凌晨2时40分，中石化青岛开发区的东黄输油管道破裂、原油泄漏。
凌晨3点，有市民看到闪烁着黄灯的车辆疾驰而过，穿着“中石化”衣服的人在街上穿行。
中石化23日披露的消息称，这条爆炸的东黄输油管道，于1986年7月建成投产。资料显示，原设计管道起自东营，途经寿光、潍坊、高密等市县，终到黄岛油库，管道长度248.5公里，管径711毫米，年输油能力1000万吨。
由于东黄输油管道已经服役二十余年，据中石化管道储运管理公司潍坊处的信息，在两次腐蚀性调查中，发现管道“防腐层已严重老化，管道状况令人堪忧”，亟须大修。
2011年，东黄输油管道进入整改议程。但当年9月一份环评公告显示，整改面临很大困难：由于建筑物离部分管道较近，无法进行管道防腐层大修。环评公告还显示改造工程主要内容包括，对东黄复线多处管道进行改线，其中包括黄岛区的黄岛油库出线段改线15-16公里。
但这一整改计划并未落实，山东省环境保护科学研究设计院一位工作人员向媒体表示，东黄复线改线工程部分标段的环评工作还在进行当中，至今未能正式动工。
今年2月底，东黄输油管道开始大修，主要包括管道防腐层的更换、电火花检漏、无损检测等。截至今年4月，东黄输油管道已完成8公里大修。在此次原油泄漏并引发爆炸前，该线路是否已经完成大修，目前尚不清楚。
今年10月，中石化举行了一场全国性安全大检查，此条管道也在检查之列。这次检查规模巨大，共查出问题8091个。但记者多方求证也没有得到回应，东黄输油管道是否也查出问题，并进行整改。
●3时15分 关闭阀门
原油渗入民用管道极易爆炸
据中石化通报，原油泄漏半个多小时后，3点15分，黄岛油库关闭输油阀门。但此时，斋堂岛街约1000平方米路面已被原油污染。更重要的是：冒溢原油进入了雨水管线。中石化新闻发言人称，原油从输油管道流入市政排水暗渠，流了12分钟。
原本应该与建筑及其他管线保持距离的石油管道，在斋堂岛街一带不仅紧邻建筑，而且与其他管交错而行。
在斋堂岛街和秦皇岛路交叉口，东西走向输油管道已完全爆裂，破损的输油管道穿过下水道暗渠，十字交叉而行，漂着黑色油污的水流从管道下面流过。不仅如此，还有近十条各种线路或紧挨石油管道，或与之交叉而行。
现场救援的中石化工程师也证实，输油管道是从地下水道中间穿过的。
国家城市环境污染控制技术研究中心研究员彭应登表示，这次事故很明显是埋在地下输送化学品的工业管网和民用的管网发生了冲突，如果只是输油管道，一旦发生泄漏，因为其特殊设计，可以很快截断其中一段，并迅速让泄漏气体在暴露空间中挥发，不太容易产生爆炸。
但这次事故中，输油管道的原油渗入了安全系数没有那么高的民用管道，后者为一个封闭的空间，“就像煤矿中充满了瓦斯一样，一遇明火极易爆炸。”彭应登说。
而市政管道中的火源很难控制。中国石油管道公司专家组成员汪冈伟称，“汽车排气管冒火星，工人维修溅起的火花，都可能引发爆炸。”
中国石油和石油化工设备工业协会首席顾问赵志明也指出，输油管道里除了原油，还会有一些气体，这些气体是易燃易爆的。单是关闭阀门了事，说明相关人员在经验上有欠缺，处理方式不当。
一位石油行业的安全应急事故处理专家在接受媒体采访时称，一旦发生原油或任何化工泄漏事件，首先采取的最重要应急措施之一就是防止泄漏物质进入下水道，因为泄漏物质一旦进入下水道，事态就会变得难以控制。
●5点 街上弥漫柴油味
市政府始终不知情
早晨5点钟，漏油点附近的整条街上已经弥漫了“柴油般的怪气味”。
5点20分左右，中石化管道储运管理公司潍坊输油处副处长邢玉庆接到运销调度科电话，说青岛黄岛区有原油泄漏，相关科室已经赶往现场，青岛输油站站长在指挥。邢玉庆认为，“这意味着应急预案已经启动”。
根据《中华人民共和国石油天然气管道保护法》(下称《管道保护法》)，发生管道事故，管道企业应立即启动本企业管道事故应急预案。
按照2011年《中国石化应急管理规定》，当发生(中石化)直属企业级等突发事件时，各单位应在1小时内向中石化办公厅总值班室、安全环保局和其他分管部门报告，并随时报送最新进展情况。
23日，青岛海事局副局长董海岩称，海事部门接到报告是在事故发生几个小时之后，已耽误了最佳的清污时间。24日，青岛市环保局副局长陈宁称，环保部门是事发当日上午8点才获知中石化泄漏事故的。
而青岛市政府知道的最晚，23日，青岛市政府副秘书长郭继山称，市政府是在爆燃事故发生后才知道漏油事故，在此之前他们对漏油并不知情。
中石化22日的通报中显示：约3点15分“开发区立即组织处置”漏油事件，并于7点30分在入海口处设置了两道围油栏。
邢玉庆称，当日将近早上6点时，青岛输油站站长又致电他称，海面上已经开始见油。地方安检和环保部门的人员已经在现场。
企业是何时向当地政府部门通报的情况？青岛市政府是否在爆炸前毫不知情？究竟应该由谁通知市政府？目前无人回应。
郭继山对媒体承认，中石化在漏油后已通知了黄岛区政府及区一级消防、交警等部门，但没有通知市政府。
一名中石化内部人士则向采访的媒体反问：“我们已经通知(黄岛)区政府了，为何区政府不去通知市政府？”
根据《管道保护法》，发生管道事故，管道企业应当向事故发生地县级人民政府主管管道保护工作的部门、安全生产监督管理部门和其他有关部门报告。这意味着，中石化应该通知的是区级政府相关部门。
●10:30 爆炸发生
附近居民未获通报
随着天光大亮，黄岛的市民们像往常一样出门上班，或是送孩子前往学校。
8点半前后，邢玉庆赶到漏油现场，十几个施工人员正在抢修，一旁公路上还有社会车辆往来穿行。
邢玉庆说，他觉得交通秩序有点乱，需要实行交通管制，就让公司公安科长打110报警，希望增加警力。
《中国石化应急管理规定》中，工作原则第一条即是坚持以人为本，减少危害的原则。牢固树立安全第一的思想，把保障员工、公众的生命和健康放在首位。
《管道保护法》更明确规定：发生管道事故，管道企业应当及时通报可能受到事故危害的单位和居民，采取有效措施消除或者减轻事故危害。
但附近的行人和居民，没人接到撤离的通知。他们在抢修人员和政府部门人员身旁穿行而过。有市民看到，在已经漏油的管道下，闪烁出电气焊的火花。
昨日，事故调查组组长、国家安全监管总局局长杨栋梁指出，这是十分严重的责任事故：泄漏后的应急处置不当，未按规定采取设置警戒区、封闭道路、通知疏散人员等预防性措施。
10时30分许，黄岛秦皇岛路附近，雨水涵道和输油管道抢修作业现场，相继发生爆燃。
