Ingxelo yophando ngengozi yekhemikhali

Iwebhusayithi esemthethweni yeSebe loLawulo lweeMeko eziNgxamisekileyo leSithili saseGuangxi Zhuang Autonomous likhuphe iNgxelo yoPhando ngengozi yoMlilo Omkhulu eBeihai LNG Co., LTD ngoNovemba 2, 2020. Ngokwengxelo, abantu abasi-7 basweleke, abantu aba-2 benzakele kakhulu kwaye ilahleko ethe ngqo kwezoqoqosho yayiyi-20.293 yezigidi zeerandi.

Unobangela wengozi okhawulezileyo

Ngexesha lokuphunyezwa kwesigaba sesibini sale projekthi, ivalvu yokwahlukanisa iyavulwa, kwaye i-LNG (igesi yendalo enyibilikisiweyo) kwi-manifold yangaphandle yoxinzelelo oluphantsi ikhutshwa emlonyeni wombhobho osikiweyo, kwaye umxube womoya we-atomized LNG kunye nomoya uvelisa ukutsha xa amandla okutsha enokwenzeka.

Unobangela ongangqalanga wengozi

Indlela yokwahlulwa kwevalvu engafanelekanga, injineli yezixhobo engahambelani nemigaqo yokungena kwezixhobo ukuze kuhlolwe kwaye kuvunywe iinkqubo kunye neenkqubo zokusebenza, iimeko zokusebenza ezishushu ziqinisekisile ukuba akwanelanga, akwanelanga ukuqonda umngcipheko wokhuseleko kunye nolawulo, "abanini bamashishini amancinci abanezivumelwano ezinkulu" indlela yombutho wemveliso yabasebenzi yenza ukuphunyezwa koxanduva lolawulo lwemveliso olukhuselekileyo alufikeleli kwindawo emiselweyo, ulawulo lwekontrakta alufikeleli kwindawo emiselweyo, njl.

Ingxelo yophando ikhankanyiwe

Ngentsasa yaloo mini, injineli yezixhobo uLai Xiaolin akazange enze uthotho lweenkqubo ezifana novavanyo lokulandelela kunye nokuqinisekiswa kwetikiti lomsebenzi odibanisa izixhobo, kodwa wangena kwisikhululo seenjineli waza wasebenza yedwa ngaphandle kweliso labanye iinjineli zezixhobo.

Ngemizuzu eyi-11:44 nemizuzwana engama-48, uLai Xiaolin wasebenzisa inkqubo ye-SIS ukuvala ngenkani ivalvu engu-0301-XV-2001. Kwangoko, ivalvu engu-0301-XV-2001 yavulwa kwaye i-LNG yaqala ukutshiza. Ngemizuzu eyi-11:45 nemizuzwana engama-00, ivalvu ivuleke ngokupheleleyo. Malunga nemizuzwana eli-10 emva kokufakwa kwe-LNG, kwaqhambuka umlilo eqongeni phambi kwetanki yokugcina i-TK-02. Kwakukho abantu abasi-8, kuquka uLiang, eqongeni phambi kwetanki yokugcina i-TK-02 kunye nomntu omnye, kuquka uTian, ​​phezu kwetanki xa i-LNG yatsha.

Ingxelo ithe

Kule ngozi, iZiko leenkonzo zeTekhnoloji yeGesi yendalo leSinopec Zhongyuan Petroleum Bureau, iBeihai LNG Company, iSinopec Tenth Construction, iHenan Hongyu, iSichuan Yitong, iSinopec Guangzhou Engineering, iQingdao Transocean zineemeko ezingekho mthethweni nezingekho mthethweni. Phakathi kwazo, iZiko leNkonzo yoBugcisa beGesi yendalo leZhongyuan Petroleum Bureau yaseSinopec laphule imigaqo yolawulo lwenkqubo yokukhusela ukuvalelwa kwezixhobo kwaye alizange liyiphumeze ngokungqongqo inkqubo yokuvunywa kokuvalelwa kwezixhobo ngokwemigaqo. Injineli yezixhobo uLai Xiaolin wenze umsebenzi wokuvalelwa ngokunyanzelekileyo ngaphambi kokuba kugqitywe imvume yetikiti lokusebenza lokuvalelwa kwaye bekungekho mlindi.

Iqela leengcali ze-HSE zamakhemikhali zomsebenzi othile lixoxe ngokukodwa ngale ngozi. Emva kokubona iintetho zengcali nganye, ndifunde lukhulu. Nazi uhlalutyo kunye nesishwankathelo:
1. Le ngozi yenzeke ngaphandle kokwahlulwa ngokufanelekileyo kwemithombo yamandla eyingozi. Bekukho iingxaki kwingqiqo yenkqubo yokuvala ungxamiseko ye-ESD kwinkqubo ye-SIS, kwaye ukumpompa ipleyiti engaboniyo akuphumelelanga. Okubaluleke ngakumbi, musa ukuyithemba kakhulu "inkqubo", nayiphi na inkqubo inokungaphumeleli.ILOTOTO (ukutshixa/ukuthega/ uvavanyo)ngonxibelelwano olubonakalayo apho kunokwenzeka. Uqinisekiso kunye nokuvunywa kuya kwenziwa ngokwegunya noxanduva lwabasebenzi bolawulo kuwo onke amanqanaba.

2. Akazange abe nenkqubo esebenzayo yokuvuma ukwenza umsebenzi onobungozi, kwaye akazange enze uvavanyo lokhuseleko lwangaphambi komsebenzi (JSA) ngaphambi komsebenzi. Ngokweenkqubo zovavanyo olungqongqo kunye nokuvuma imisebenzi eyingozi, umfaki-sicelo kunye nomphathi kufuneka basebenzise ngokungqongqo uvavanyo lokhuseleko ngaphambi komsebenzi, kwaye imvume kufuneka iye kwindawo ukuze iqinisekiswe ngaphambi kokuba ivunywe.

3. Ingxelo yophando lwengozi ibonakala ilumkile kakhulu, kwaye kwanamanqaku kunye nemizuzu icacile: ngo-11:20, icala elikufutshane netanki linqunyulwe, kwaye ngo-11:40, kutheni ucela ukuba uphathe itikiti lomsebenzi elidibanisa izixhobo? Okwesibini, le valve kufuneka ibe yivalvu yokusika esezantsi. Yavalwa nini kwaye njani? Abantu abaninzi abazange bayiqonde ivalvu evaliweyo ukuze bakhuthaze injineli ukuba ivale ivalvu kwakhona. Imibuzo emininzi malunga neenkcukacha, kodwa akukho ngqwalasela, akukho ntambo. Kunzima ukuyiqonda.
