Lipoti la kafukufuku wa ngozi ya mankhwala

Webusaiti yovomerezeka ya Dipatimenti Yoyang'anira Zadzidzidzi ya Guangxi Zhuang Autonomous Region idatulutsa Lipoti Lofufuza za Ngozi Yaikulu ya Moto ku Beihai LNG Co., LTD pa Novembala 2, 2020. Malinga ndi lipotilo, anthu 7 adamwalira, anthu awiri adavulala kwambiri ndipo kutayika kwachuma mwachindunji kunali ma yuan 20.293 miliyoni.

Choyambitsa ngozi nthawi yomweyo

Pakukhazikitsa gawo lachiwiri la polojekitiyi, valavu yodzipatula imatsegulidwa, ndipo THE LNG (gasi wachilengedwe wosungunuka) mu low-pressure external transmission manifold imatulutsidwa kuchokera pakamwa pa chitoliro chodulidwa, ndipo chisakanizo cha mpweya wa LNG ndi mpweya zimapangitsa kuyaka pamene mphamvu yoyatsira ikupezeka.

Chifukwa chosadziwika cha ngozi

Njira yolakwika yodzipatula ma valavu, mainjiniya wa zida osatsatira malamulo a chipangizo cholumikizira kuti ayang'ane ndi kuvomereza njira zogwirira ntchito, momwe zinthu zimagwirira ntchito motentha zatsimikizira kuti kusakwanira, kusakwanira kwa chidziwitso cha chitetezo ndi kuwongolera, "eni mabizinesi ang'onoang'ono omwe ali ndi mgwirizano waukulu" njira yogwirira ntchito yopangira antchito imapangitsa kuti udindo woyendetsa bwino ntchito usafike pamalo osankhidwa, oyang'anira makontrakitala safika pamalo osankhidwa, ndi zina zotero.

Lipoti la kafukufuku linatchula

M'mawa wa tsiku limenelo, injiniya wa zida Lai Xiaolin sanachite njira zingapo monga kufufuza kotsatira ndi kutsimikizira tikiti yogwirira ntchito yolumikizana ndi zida, koma analowa m'malo opangira zida ndikugwira ntchito yekha popanda kuyang'aniridwa ndi mainjiniya ena a zida.

Pa mphindi 11:44 ndi masekondi 48, Lai Xiaolin anagwiritsa ntchito makina a SIS kuti atseke mwamphamvu valavu 0301-XV-2001. Nthawi yomweyo, valavu 0301-XV-2001 inatsegulidwa ndipo LNG inayamba kupopera. Pa mphindi 11:45 ndi masekondi 00, valavuyo inatsegulidwa kwathunthu. Patatha masekondi pafupifupi 10 kuchokera pamene LNG inalowetsedwa, moto unabuka pa nsanja patsogolo pa thanki yosungiramo zinthu ya TK-02. Panali anthu 8, kuphatikizapo Liang, pa nsanja patsogolo pa thanki yosungiramo zinthu ya TK-02 ndi munthu m'modzi, kuphatikizapo Tian, ​​pamwamba pa thankiyo pamene LNG inayaka moto.

Lipotilo linati

Pa ngoziyi, sinopec Zhongyuan Petroleum Bureau natural Gas Technology service Center, Beihai LNG Company, Sinopec Tenth Construction, Henan Hongyu, Sichuan Yitong, Sinopec Guangzhou Engineering, Qingdao Transocean ali ndi zochitika zosaloledwa komanso zosaloledwa. Pakati pawo, Natural Gas Technical Service Center ya Zhongyuan Petroleum Bureau ya Sinopec inaphwanya malamulo oyang'anira chitetezo cha zida zolumikizirana ndipo sinatsatire njira yovomerezeka yolumikizirana zida motsatira malamulo. Mainjiniya wa zida Lai Xiaolin adachita ntchito yolumikizirana mokakamiza asanafike nthawi yovomerezeka ya tikiti yolumikizirana ndipo panalibe womusamalira.

Gulu la akatswiri a HSE a mankhwala a ntchito inayake linakambirana mwapadera za ngoziyi. Nditawona mawu a katswiri aliyense, ndinaphunzira zambiri. Nazi kusanthula ndi chidule chake:
1. Ngozi iyi idachitika popanda kusiyanitsa bwino magwero amphamvu oopsa. Panali mavuto mu njira yozimitsa mwadzidzidzi ya ESD mu SIS system, ndipo kupompa kwa blind plate sikunathandize. Chofunika kwambiri, musadalire "dongosolo" kwambiri, dongosolo lililonse likhoza kulephera.LOTOTO (Lockout/tagout/ mayeso)ndi mgwirizano weniweni ngati n'kotheka. Chitsimikizo ndi kuvomereza zidzachitika malinga ndi ulamuliro ndi udindo wa ogwira ntchito oyang'anira pamlingo uliwonse.

2. Sanakhale ndi njira yothandiza yovomerezera ntchito yoopsa, ndipo sanachite kafukufuku wa chitetezo asanayambe ntchito (JSA) asanapite kuntchito. Malinga ndi kafukufuku wokhwima komanso njira zovomerezera ntchito zoopsa, wopemphayo ndi woyang'anira ayenera kutsatira mosamala kafukufuku wa chitetezo asanayambe ntchitoyo, ndipo chilolezocho chiyenera kupita kumaloko kuti akatsimikizire ntchitoyo asanavomerezedwe.

3. Lipoti la kafukufuku wa ngozi likuoneka kuti ndi losamala kwambiri, ndipo ngakhale mfundo ndi mphindi zake zili bwino kwambiri: nthawi ya 11:20, mbali yomwe ili pafupi ndi thanki yadulidwa, ndipo nthawi ya 11:40, n’chifukwa chiyani mukupempha kuti mugwire tikiti yogwirira ntchito yolumikizira zida? Chachiwiri, valavu iyi iyenera kukhala valavu yodula yamadzimadzi yochepa. Inatsekedwa liti ndipo inatsekedwa bwanji? Anthu ochepa sanamvetse valavu yotsekedwa kuti alimbikitse mainjiniya kuti atseke valavu kachiwiri. Mafunso ambiri okhudza tsatanetsatane, koma palibe cholinga, palibe ulusi. N’zovuta kumvetsa.
