Umbiko wophenyo ngengozi yamakhemikhali

Iwebhusayithi esemthethweni yoMnyango Wezokuphathwa Kwezimo Eziphuthumayo we-guangxi Zhuang Autonomous Region ikhiphe uMbiko Wophenyo Ngengozi Yomlilo Omkhulu eBeihai LNG Co., LTD ngoNovemba 2, 2020. Ngokusho kombiko, abantu abayi-7 bashonile, abantu ababili balimala kabi kanti ukulahlekelwa kwezomnotho ngqo kwaba yi-yuan eyizigidi ezingama-20.293.

Imbangela yengozi esheshayo

Ngesikhathi sokuqaliswa kwesigaba sesibili salo msebenzi, i-valve yokuhlukanisa iyavulwa, bese i-LNG (igesi yemvelo encibilikisiwe) ku-manifold yokudlulisa yangaphandle enengcindezi ephansi ikhishwa emlonyeni wepayipi elisikiwe, bese ingxube yomoya nomoya we-LNG oxutshwe ne-atomized ikhiqiza ukushisa lapho amandla okushisa engenzeka.

Imbangela engaqondile yengozi

Indlela yokuhlukaniswa kwama-valve engafanele, unjiniyela wezinsimbi ongahambisani nezinhlinzeko ze-interlock yezinsimbi ukuze kuhlolwe futhi kuvunyelwe izinqubo kanye nezinqubo zokusebenza, izimo zokusebenza ezishisayo ziqinisekisile ukuthi ukungazi kahle, ukungazi kahle kanye nokulawula ingozi yokuphepha, "abanikazi bamabhizinisi amancane abanenkontileka enkulu" imodi yenhlangano yokukhiqiza abasebenzi yenza ukuqaliswa komthwalo wemfanelo wokuphathwa kokukhiqiza okuphephile akufinyeleli esikhundleni esibekiwe, ukuphathwa konkontileka akufinyeleli esikhundleni esibekiwe, njll.

Umbiko wophenyo okukhulunywe ngawo

Ekuseni ngalolo suku, unjiniyela wezinsimbi zomculo uLai Xiaolin akazange enze uchungechunge lwezinqubo ezifana nokuhlolwa kokulandelela kanye nokuqinisekiswa kwethikithi lomsebenzi elixhumene nezinsimbi, kodwa wangena esiteshini sonjiniyela wasebenza yedwa ngaphandle kokugadwa abanye onjiniyela bezinsimbi zomculo.

Ngo-11:44 imizuzu nemizuzwana engama-48, uLai Xiaolin wasebenzisa uhlelo lwe-SIS ukuvala ngenkani i-valve 0301-XV-2001. Ngokushesha, i-valve 0301-XV-2001 yavulwa futhi i-LNG yaqala ukufutha. Ngo-11:45 imizuzu nemizuzwana engama-00, i-valve yayisivuleke ngokuphelele. Cishe ngemva kwemizuzwana eyi-10 yokujova i-LNG, kwaqubuka umlilo epulatifomu phambi kwethangi lokugcina i-TK-02. Kwakunabantu abayi-8, kuhlanganise noLiang, epulatifomu phambi kwethangi lokugcina i-TK-02 nomuntu oyedwa, kuhlanganise noTian, ​​phezulu ethangini lapho i-LNG ivutha amalangabi.

Umbiko uthe

Kule ngozi, i-sinopec Zhongyuan Petroleum Bureau Natural Gas Technology Service Center, iBeihai LNG Company, iSinopec Tenth Construction, iHenan Hongyu, iSichuan Yitong, iSinopec Guangzhou Engineering, iQingdao Transocean inezimo ezingekho emthethweni nezingekho emthethweni. Phakathi kwazo, i-Natural Gas Technical Service Center yeZhongyuan Petroleum Bureau yeSinopec yephule imithetho yokuphatha yohlelo lokuvikela ukukhiya kwezinsimbi futhi ayizange isebenzise ngokuqinile inqubo yokugunyaza ukukhiya kwezinsimbi ngokwemithetho. Unjiniyela wezinsimbi uLai Xiaolin wenze umsebenzi wokukhiya okuphoqelekile ngaphambi kokuba kuqedwe ukugunyazwa kwethikithi lokusebenza lokukhiya futhi kwakungekho mqaphi.

Iqembu lochwepheshe be-HSE yamakhemikhali bomsebenzi othile baxoxe ngokukhethekile ngale ngozi. Ngemva kokubona izinkulumo zochwepheshe ngamunye, ngafunda okuningi. Nansi ukuhlaziywa kanye nesifinyezo:
1. Le ngozi yenzeke ngaphandle kokuhlukaniswa okusebenzayo kwemithombo yamandla eyingozi. Kube nezinkinga endleleni yokusebenza yokuvala okuphuthumayo kwe-ESD ohlelweni lwe-SIS, futhi ukupompa kwepuleti elingaboni kwehlulekile ukudlala indima. Okubaluleke kakhulu, ungathembi "uhlelo" kakhulu, noma yiluphi uhlelo lunethuba lokwehluleka.I-LOTOTO (Ukukhiya/ukuthega/ukuhlolwa)ngokuxhumana okungokoqobo lapho kungenzeka khona. Ukuqinisekiswa nokuvunywa kuzokwenziwa ngokwegunya kanye nomthwalo wemfanelo wabasebenzi bokuphatha kuzo zonke izigaba.

2. Akazange abe nenqubo ephumelelayo yokugunyaza ukwenza umsebenzi oyingozi, futhi akazange enze ukuhlolwa kokuphepha kwangaphambi komsebenzi (i-JSA) ngaphambi komsebenzi. Ngokwezinqubo zokuhlola eziqinile kanye nokugunyaza imisebenzi eyingozi, umfakisicelo kanye nomphathi kufanele basebenzise ngokuqinile ukuhlolwa kokuphepha ngaphambi kokusebenza, futhi imvume kufanele iye endaweni ukuze iqinisekiswe ngaphambi kokugunyazwa.

3. Umbiko wophenyo lwengozi ubonakala uqaphile kakhulu, futhi ngisho namaphuzu nemizuzu kucacile kakhulu: ngo-11:20, uhlangothi oluseduze nethangi selunqunyiwe, kanti ngo-11:40, kungani unxusa ukuphatha ithikithi lomsebenzi elixhumene nethuluzi? Okwesibili, leli valve kufanele libe yivalvu yokusika esezingeni eliphansi loketshezi. Lavalwa nini futhi kanjani? Abantu abambalwa abazange baqonde ukuthi ivalvu ivaliwe ukuze banxuse unjiniyela ukuthi aphinde avale ivalvu. Imibuzo eminingi mayelana nemininingwane, kodwa akukho ukugxila, akukho ntambo. Kunzima ukuyiqonda.
