VA Connecticut Health Care System's kwikhampasi yaseWest Haven njengoko ijongwe kwiSitrato saseWest Springs nge-20 kaJulayi, ngo-2021.
I-Westport-Uphando lwe-Federal lwafumanisa ukuba nge-13 kaNovemba ka-2020, i-flange yentsimbi elula kumgca womphunga owalupheleyo kwisakhiwo seZiko lezoNyango lweMicimbi yeVeterans ngequbuliso yaqhekeza ibe ziziqwenga ezine, ikhupha umphunga ophakamileyo kwaye yabulala amadoda amabini.
Uphando lwe-VA malunga nengozi luchaza iziganeko zasekuseni, zichaza indlela uJoseph O'Donnell, ikontrakthi eqeshwe ukulungisa ukuvuza kwipayipi, yangena phantsi kweSakhiwo 22 emva kokulungiswa, kunye no-Euel Sims Jr., i-plumbing isuphavayiza, kunye Ukusilela kwezixhobo kunye nemilinganiselo yokhuseleko eyakhokelela ekufeni kwabo.Ukusukela ngoko, uVirginia wenze okanye wacwangcisa utshintsho oluninzi, kubandakanywa iprojekthi yokuphucula umphunga.
Kodwa ingxelo ithi izinto ezibe negalelo kwesi sehlo sika-2020 ziquka imibhobho yamanzi ebindala nengasafikeleliyo kwimigangatho yempahla ekhoyo ngoku, iivalvu ezingafakwanga kakuhle kunye nemibhobho ekhokelela kumanzi amileyo, nokutyholwa ngokungalandeli iinkqubo zokugcina amadoda ekhuselekile.
Umnyango weSitrato saseWest Springs we-VA Connecticut Health Care System kwikhampasi yaseWest Haven, efotwe nge-20 kaJulayi, ngo-2021.
Ekugqibeleni, xa la madoda evula imibhobho, umphunga wavuthuza kumbhobho we-intshi ezi-6, kwaye uxinzelelo lwalulukhulu kangangokuba i-flange efakwe ezantsi ye-dropper ethe nkqo yagqabhuka yaziingceba ezine, ivuthela umphunga egumbini.
Ingxelo yophando ye-VA, ekhutshwe ngo-Ephreli 15, ifunyenwe yiNew Haven Registry ngesicelo seNkululeko yoLwazi.Amagama abasebenzi bonke ahlelwe.
Isiganeko sakhokelela ekuhlaziyweni kokungaphumeleli kwe-West Haven Virginia, okubangelwa izaziso ezisithoba ze-OSHA kunye nokubiza iCongress ukuba iphinde ivuselele iziko lezonyango.
Ngokwengxelo, uthotho lweziganeko lwaqala ngo-Okthobha okanye ngoNovemba ka-2020, xa ukhuseleko lwaseVirginia lwaxelelwa ngokuvuza kwigumbi lokugcina kwiSakhiwo sama-22, kufutshane nesiphelo sendlela enkulu ekungeneni kweCampbell Avenue. isebe lemibhobho kwafuneka ukuba ukwahlula umphunga kwisakhiwo ukuze kuncitshiswe asbestos.Umsebenzi abatement wagqitywa ngoNovemba 9, kwaye umphunga uhlala off.
Nge-13 kaNovemba, umhlali waseDanbury kunye nonokontraka waseDanbury uMulvaney Mechanical assembler umphunga u-O'Donnell ugqibezele ukulungisa indawo evuzayo ngo-7:45 amNgo 8:00, uSims, igqala leNavy Seabees kunye nomhlali waseMilford, wazisa umphathi wakhe ukuba uzimisele ukubuyisela umva umphunga. Amadoda amathathu awela isitrato esiya kweso sakhiwo, kodwa umphathi weSims wacelwa ukuba avule igumbi elahlukileyo kwiSakhiwo sama-22, ingxelo yathi. U-O'Donnell kunye noSims kuthiwa baqhubela phambili kwigumbi elingaphantsi komatshini kwiSakhiwo sama-22 ukuze bavule. ivalve yomphunga.
Malunga nentsimbi yesi-8:10, ingxelo yathi, “Umphathi wenkqubo yezinto eziluncedo weva isithonga esikhulu waza wabona umsinga womoya uphuma kwizinyuko ezikhokelela kwigumbi loomatshini. Ilahleko yoxinzelelo lomphunga … yarekhodwa kwindawo yokubiyela. … ubushushu obuphezulu I-alam ibangele i-alam yomlilo, kwaye ingcali yokhuseleko yemka ngoko nangoko ukuya kuphanda ngesivusi esixeliweyo kwiSakhiwo sama-22. Ukongeza, ngeli xesha, umphathi weenkqubo eziluncedo kunye nomnye umsebenzi weziko lonzakele ngelixa bezama ukungena kwigumbi lomatshini elingaphantsi. ”
Isityalo sebhoyili saseVirginia savalwa, kwaye iSebe lezoMlilo laseWest Haven, iPolisa yaseVirginia State kunye nabaphenduli bokuqala baphendule.
“Emva kokwehla koxinzelelo lomphunga nobushushu kwelo gumbi, abasebenzi bongxamiseko bakwazi ukungena kwelo gumbi, kodwa ngeli xesha umphathi wevenkile yemibhobho yamanzi kunye nonokontraka oomatshini babesele befile,” yatsho le ngxelo. De kwayintsimbi yokuqala emva kwemini; malunga ne-2:15, ixhoba lathatyathwa.
Uphando lwe-VA nge-Applied Technical Services e-Marietta, eGeorgia, lwafumanisa ukuba ukukhutshwa komphunga ogqithisiweyo kwakunamandla kangangokuba amadoda amabini azama ukutyhala umnyango kwigumbi le-8-by-12-foot ayikwazanga. zalutshisa unyawo lwakhe kumanzi ashushu, itsho ingxelo.
Umfanekiso ovela kwiSebe leMicimbi yamagqala e-US "West Haven Steam Rapture, Board of Inquiry Investigation" ingxelo yememo, yomhla we-15 ka-Epreli, 2021, ebonisa "Ubumbeko lwePipe-Ixesha loPhando."
"Xa i-cast iron flange ingaphumeleli, i-6" umgca we-steam oyintloko wakwazi ukukhupha egumbini," yatsho ingxelo. "Igumbi laxinzelelwa ngumphunga xa umphunga waqala ukugeleza kwigumbi usuka kumgca womphunga ongathintelwanga. Olu xinzelelo ludala amawaka eekhilogram zamandla ngaphakathi komnyango, ukunyanzela ukuba kuvalwe. Kweli nqanaba, akunakwenzeka ukuvula. umnyango ongenazo izixhobo ezinzima.”
Ithuba leeveki ezimbini phakathi kwengxelo yokuqala yokuvuza komphunga kwiSakhiwo sama-22 kunye nomhla wengozi, kudityaniswe nemibhobho yedriphu engafanelekanga, yayingunobangela wokufa, yatsho ingxelo. Umphunga uvaliwe, " okubangele ukwakhiwa okukhulu kwe-condensate kunye nokupholisa imibhobho, enokuthi ibe yimbangela yengozi, "yatsho. Ngokumalunga neekota ezintathu zeelitha zamanzi kwi-dropper, akukho mvula okanye i-valve yokukhupha i-drain efunekayo. .
Abaphandi bathi i-flange eqhekekileyo ifakwe kwi-flange engenanto ekupheleni kwe-dropper kwaye kufuneka ifakwe kwi-welded, ingaxutywanga, kumbhobho.
Iiflange zagqabhuka emva “komzuzwana oqhelekileyo wesando samanzi esinempembelelo enkulu.” Ihamile yamanzi yi-hydraulic shock wave ebangelwa ngamanzi okanye umphunga unyanzeleke ukuba ume ngequbuliso okanye ujike icala uze ubethe ivalve okanye omnye umqobo. Ngokuqhelekileyo kubangelwa ukuqokelela kwamanzi kwimibhobho yomphunga.
Xa ivalve ivuleka kwaye umphunga ungena kumbhobho kwigumbi lomatshini, ubetha amanzi apholileyo kwidropha ngeziphumo ezibi.” Oku kuhamba ngokutsha komphunga kunokubangela ukufudumeza ngequbuliso kunye nokudanyaza kwecondensate emileyo okanye engasuswanga kuyo nayiphi na indawo engathotywanga yomphunga oyintloko. imibhobho,” yatsho ingxelo. ” kwaye “ngoyena nobangela wokusilela ngequbuliso kweentsimbi ezingwevu”.
Ingxelo ithi: "I-flange ekujoliswe kuyo ifumene ukusilela komthwalo ngenxa yomthwalo ongaphaya koko ibinokuwuthwala."
Umfanekiso ovela kwi-15 ka-Epreli, i-2021 yeSebe leMicimbi yamagqala e-US "I-West Haven Steam Rapture, iBhodi yoPhando" ingxelo yememo ebonisa "umonakalo we-flange" kwiSakhiwo sama-22.
“Ixesha eligqithileyo phakathi kokungena esithubeni kunye nokuvula iivalve kwindawo abayifumeneyo libonisa ukuba le nkqubo ayizange iphinde isebenze ngokufanelekileyo. Olu hlobo lwenkqubo lufuna ubushushu obucothayo kunye nokucothayo kunye nokulingana koxinzelelo, ”iphawulile.
“Abasebenzi bavule i-75% yevalve yomphunga #1. Baphinde bavula ivalve yebhola ekwindawo yokucoca umgca womphunga wecondensate,” yatsho ingxelo. Ezinye iivalve ezimbini nazo bezivuliwe, enye i-5% ukuya kwi-6%, enye ivule i-11%.
Umfanekiso ovela kwiSebe leMicimbi yamagqala e-US "I-West Haven Steam Rupture, iBhodi yoPhando" yengxelo yememo, yomhla we-15 ka-Epreli, ngo-2021, ebonisa "UQhakamshelwano lwemibhobho enemisonto, iDrip Ezantsi."
"Ukuvulwa kwevalve yebhola kufuneka kunikeze ingxelo ngokukhawuleza kubasebenzi ngendlela yokuhamba komphunga kunye nokuhamba kwe-condensate ukubonisa ukuba kuyasebenza," abaphandi bathi. "Ulandelelwano oluchanekileyo apho ivalve nganye ivula khona ayicacanga, kodwa kungcono ukuvula umgca we-condensate kuqala." Ivalve yebhola encinci. "
Nangona kunjalo, ngelixa ingxelo ichaza ukuba ukuvula ivalve yebhola kuya kukhupha i-condensate ukusuka kumgca okanye ngaphezulu, ayizukuwakhupha onke amanzi kumgca wokuthontsiza "kwaye le ndawo yomgca ophambili womphunga isaqulathe i-3/4 galoni ye-condensate. .”
Ingxelo yathi i-plumbing kwi-Building 22 iphule iikhowudi ezininzi. Iiflange zensimbi eziphosiweyo azivumelekanga kwiinkqubo zemibhobho ye-steam phantsi kwezi khowudi, kodwa azinqatshelwe yi-VA okanye i-ASME codes, ingxelo yathi. "Akukho bungqina bokuba uVirginia uyalele. nabani na ngaphambili ukuba asuse okanye atshintshe iflange,” yatsho.
Ukongezelela, i-steam trap ifakwe kufuphi kakhulu ngaphantsi kombhobho we-drip, "i-valve yokuhlukanisa i-valve ye-butterfly, engavumelekanga phantsi kwekhowudi ye-VA," yatsho ingxelo.
Enye ingxaki, le ngxelo ithi, "kukungakwazi ukwahlula nayiphi na imigca emithathu engundoqo yomphunga, okwenza kube nzima ukuba iplanti yebhoyila iqinisekise ukhuseleko lwaso sonke isikhululo sebhoyila".

Abaphandi baphinde batyhola i-VA yokunqongophala kweenkqubo ezenzelwe ukukhusela abasebenzi kwiimeko zezinto ezinobungozi.Inkqubo yokuvala i-tagout / i-tagout ithintela ukuba umphunga ungaphindi ujike nabani na ngaphandle komntu owucimileyo.
Ngokwengxelo: “Isitshixo se-VA kunye netyathanga zifunyenwe kwindawo ekufutshane nevalve yegumbi, ebonisa ukuba inkqubo inokuba itshixiwe. Nangona kunjalo, akukho zilogi ze-Lockout tagout (LOTO), iimvume okanye iinkqubo zeLOTO zesistim. Akukho kukhangelwa kweeofisi kufumene iilog zeLOTO okanye iinkqubo zezi valve okanye izakhiwo.
Unxibelelwano phakathi kokhuseleko, imibhobho yamanzi kunye nobunjineli nalo aluphumelelanga: “Iziko lokubilisa amanzi alizange liziswe ngolu kuvalwa, yaye alizange liziswe nangokuvalwa okuqhubekayo. Akukacaci ukuba ubunkokeli bobunjineli okanye ukhuseleko belulwazi olu suku. umsebenzi oqhubekayo,” itshilo ingxelo.” Iqela alikwazanga ukumisela ukuba kutheni unokontraka ekweli gumbi. Iqela alifumananga bungqina bokutshixa okongezelelekileyo okubekwe ngunokontraka.”
NgoMeyi 12, i-OSHA ikhuphe izaziso ezisithoba malunga neemeko zokusebenza ezingakhuselekanga okanye ezingafanelekanga e-Connecticut, kuquka ukwazisa abaqhubi bezityalo zebhoyila ukuba baphume / bakhuphe kwimigca yemveliso; ukusilela ukwazisa iMulvaney Mechanical ngeenkqubo zayo zeLOTO; okanye ukuvalwa ngocwangco kwezixhobo” ukwenzela ukuba i-condensate ikhutshwe kwisistim.Yathi "iinkqubo azizange ziphuhliswe, zibhalwe kwaye zisetyenziswe ukulawula amandla anokuba yingozi" okanye iteknoloji esetyenziselwa ukusebenzisa ivalve.
Ukongeza, i-OSHA yafumanisa ukuba i-VA ayizange iqinisekise ukuba indawo yokusebenzela yayingenazo iingozi ezinokubangela ukufa okanye ukulimala, kwaye abaphathi abazange baqeqeshwe ngendlela yokuqonda nokunciphisa iingozi ngaphakathi kwendawo yabo yoxanduva.
Umfanekiso ovela kwiSebe leMicimbi yamagqala e-US "I-West Haven Steam Rapture, iBhodi yoPhando" yengxelo yememo, yomhla we-15 ka-Epreli, ngo-2021, ebonisa "iSteam Line Schematic, iBasement 22."
I-OSHA ngaphambili ikhankanya ukuphulwa okuthathu kwi-2015: Ukujonga iinkqubo zokulawula amandla ubuncinane ngonyaka; ukungaphumeleli ukubonelela ngoqeqesho emva kokufaka ivalve entsha yomphunga kwiSakhiwo sama-22; kunye nokusilela ukuncamathisela izixhobo zeLOTO zobuqu kwiqela lezixhobo zeLOTO ngabasebenzi.
"Ezi zibulalayo zazinokuthi ziphetshwe ukuba abaqeshi balandela imigangatho yokhuseleko eyenzelwe ukuthintela ukukhutshwa okungalawulwayo kwe-steam," kusho umlawuli wengingqi ye-OSHA uSteven Biassi ngelo xesha. ngokungeyomfuneko.”
Umnyango weCampbell Avenue we-VA Connecticut Health Care System kwikhampasi yaseWest Haven, efotwe nge-20 kaJulayi, 2021.
U-Pamela Redmond, isithethi se-West Haven Medical Centre eVirginia, wathi kwi-imeyile ukuba inkqubo yaseVirginia e-Connecticut "ibe ikwimo eguquguqukayo ukususela kwiziganeko ezibuhlungu ze-13 kaNovemba 2020. Umsebenzi onzima wenziwa ukuphucula ukhuseleko kunye uhlaziyo olukhulu lwenziwe kwiinkqubo zokhuseleko. ”
I-VA Connecticut Healthcare System kwikhampasi yaseWest Haven njengoko ijongwe kwiSitrato sase-Spring nge-20 kaJulayi, ngo-2021.
Iinkonzo zoLawulo lweZibonelelo “zikwinkqubo yohlengahlengiso okanye yokudiliza inkqubo yomphunga kwiSakhiwo 22. Nje ukuba inkqubo entsha ifakwe, inkqubo entsha yeLO/TO iya kuphuhliswa,” wabhala.
Ukwathe: “Ngomhla wama-20 kuDisemba, 2020, kwafakelwa isitshixo sevalve evala kabini kunye neyokopha kumzi-mveliso wokubilisa umphunga kwiSakhiwo sama-22 apho yenzeke khona ingozi. Inkqubo entsha yevalvu ivumela ukukhutshwa kwamandla agciniweyo okanye angaphezulu, umzekelo kwisixokelelwano samanzi ajingisiweyo akhutshiweyo kumbane.
U-Redmond uthe izakhiwo ezibini ezikhulu ziphantsi kweeprojekthi zokuphucula umphunga, kwaye inkqubo inikwe ikhontrakthi yokutshintsha imigibe yomphunga kwiSakhiwo sayo sama-22.
"I-Virginia Connecticut State iyaqhubeka nokusebenza ngokusondeleyo neofisi yethu yengingqi, i-Veterans Health Administration kunye ne-OSHA ukuqinisekisa ukhuseleko lomntu wonke kwiindawo zethu zokhathalelo," wabhala uRedmond.
USen. Richard Blumenthal, D-Conn., Ilungu leKomiti yeMicimbi yeSenate yase-US, uthe ukhuthaza ingxowa-mali yeziseko ezingundoqo "ukuvuselela nokuvuselela indawo yaseWest Haven Virginia" kunye nezinye izibhedlele ezininzi zaseVirginia kulo lonke ilizwe.
Isicwangciso semisebenzi kaMongameli uJoe Biden sikaMongameli uJoe Biden sika-2.65 setriliyoni semisebenzi yaseMelika siquka i-18 yeebhiliyoni zeerandi ukwenza izibhedlele ze-VA kunye neekliniki zibe zezanamhlanje.
"Intlekele ye-Nov. 13 yayiyeyona nto imbi kakhulu yokusilela kweziseko zophuhliso," utshilo uBlumenthal. "Le ngxelo ikholisa kakhulu; ayiqinisekisi kuphela [iqaqambisa] iintsilelo kwizakhiwo ezikhoyo, kodwa kwakhona ukungxamiseka kokulungiswa kwezakhiwo nokuzisa izakhiwo kwinkulungwane yama-21, kunokusebenzisa nje iindlela ezingcono. I-Lan kunye nezinye izilungiso zexesha elifutshane ukuze udibanise iziphene. UVirginia kufuneka atyale imali kwisakhiwo esitsha. ”
UBlumenthal uthe iZiko lezoNyango laseWest Haven eVirginia kufuneka lakhiwe ngokutsha, kodwa khange akwazi ukuqikelela esidlangalaleni ukuba iza kuba yimalini. amanyathelo angxamisekileyo,” utshilo.
