Ekuseni ngoSepthemba 5, 2008, osebenza ngamapayipi wabizwa kwa-A-1 Mushroom Substratum Ltd. e-Langley, British Columbia. Lokhu kwase kungokwesibili ezinsukwini ezimbalwa. Lapho, wathola ukuthi ipayipi lokungena elingaphansi kweshede lokumpompa lalivalwe ngokuphelele, futhi wabikela umphathi wendawo yokwenza umquba wamakhowe ukuthi kudingeka inkampani enolwazi lokumpompa indle.
Kunalokho, ngaphansi kokuqondisa komphathi, izisebenzi ezimbili zazama ukususa ukuvaleka kwe-valve uvemvane epayipini. Phakathi nemizuzwana ngemva kokuvula iflenge, isisebenzi sawela ngobuso emanzini ngaphansi kweshede, okukholakala ukuthi ngenxa yokukhishwa kungazelelwe kwegesi ye-hydrogen sulfide (H2S) endaweni entula umoya-mpilo.Uzofa.
Emizuzwini embalwa ezayo, abatakuli ababili abangaba khona abavela ebhizinisini lokutshala nokucubungula amakhowe elinabaqashi abaningi bazoba nesiphetho esifanayo.Abanye abasebenzi ababili-ngenhlanhla bazobhekana nokulimala okucishe kubulale, okungenakulungiseka.
Embikweni wophenyo okhishwe ekupheleni kukaNovemba, i-WorkSafeBC izoveza uchungechunge lokwehluleka ekwakhiweni, ekwakhiweni nasekusebenzeni kwesikhungo.Ibhodi labaqondisi lithe uphenyo lungase lube “luyinkimbinkimbi kakhulu emlandweni we-WorkSafeBC. ” “Kuzothatha izinyanga ukuvakashela izindawo ezibalulekile lapho kusetshenzwa khona; kuzothatha izinyanga ezimbalwa ukuqonda ngokugcwele izinqubo zezimboni ezihilelekile kanye nezenzakalo phakathi neminyaka emihlanu. Ukulandelana kwezenzakalo nezinqumo ezitholakalayo.q
Ngalolo suku lwango-September, izisebenzi ezimbili zazizama ukukhuculula ipayipi elivaliwe eshedini lokumpompa, kuyilapho umphathi wabo ebuka endaweni ephakeme ngamamitha amathathu ukusuka emnyango wesakhiwo. cm ngaphansi kweshede, kwakhipha amabhawodi agqwalile angu-8 ku-flange yevalvu, futhi kwafakwa ngokukhululekile amabhawodi amasha angu-4 ukuze kubambe ivalve endaweni.
Ngezithuba zabo-17:00, omunye wabasebenzi wasebenzisa i-screwdriver ukuze akhiphe iflenge eliphezulu kuvalvu, wabe esesebenzisa esinye i-screwdriver ukukhipha utshani, udaka nezinye izinto ezibhajwe kuvalvu.” Kwaqala ukugeleza uketshezi oluncane. ,” kusho umbiko wophenyo we-WorkSafeBC e-Richmond, eBritish Columbia.
Ngesikhathi isisebenzi sikhipha utshani, sakhala kumphathi ngephunga, nokwaholela ekutheni umphathi avumele isisebenzi siphume eshede.
Isisebenzi sevalvu sathatha isinyathelo sabe sesiwela phansi ngobuso emanzini kanye nodaka. Umphathi wehla futhi wasiza isisebenzi sesibili ukuba sisekele isisebenzi esingasabeli ukuze sihlale eduze kodonga lweshede. Umphathi wabe esebiza umnikazi ukuze athole usizo oluphuthumayo. .
Lapho abezimo eziphuthumayo befika ngabo-5:20 ntambama, bathola ukuthi umqondisi ongaphandle kweshede wayelahlekile futhi ephethwe ukuphefumula kanzima.” Izisebenzi ze-ambulensi zabona iphunga elibi, zasola ukuthi kwakuyingozi, futhi zanquma ukuhoxa. indawo echithekile,” kubika i-WorkSafeBC, ivimbe abanye abasebenzi abafika ngeladi ukuba bangene eshede.
Sekukonke, abasebenzi abahlanu abavela ezinkampanini ezintathu ezakha indawo yokucubungula i-A-1 Mushroom Substratum, i-HV Truong Ltd. (inkampani etshala amakhowe) kanye ne-Farmers' Fresh Mushrooms Inc. (inkampani yokupakisha nokumaketha) bakhishiwe indawo yokuhlala .Ut Van Tran, 35, Chi Wai Chan, 55, kanye no-Han Duc Pham, 47, bashonile; UTchen Phan usahamba ngesihlalo esinamasondo kanti uMichael Phan uqulekile.
Umbiko we-WorkSafeBCos uveze ukushiyeka okuningi: ukungabikho kwesistimu ye-OH&S esizeni; ukwehluleka ukulungisa izimo ze-anaerobic (anaerobic) ezikhiqizwa ethangini lenqubo elimpompa amanzi epayipini, okuholela ekunqwabelaneni kwe-H2S epayipini elingenisayo; ukuntula isivikelo ezintweni eziqinile ezingena kumapayipi okulawula Ubunjiniyela; ukuntula ukuthobela imithetho; ukushoda ekwakhiweni, ekwakhiweni nasekusebenzeni kwezikhungo kusukela ngo-2004.
Umqondisi Wezophenyo wakwaWorkSafeBC uJeff Dolan uthe: Siyaqaphela ukuthi le mindeni kumele ilinde isikhathi eside ukuze ifunde kabanzi ngokwenzeka kwabathandekayo bayo. Izizathu ziyaqondakala. ”, kusho isimemezelo sabezindaba.
Ngo-Agasti 2010, i-A-1 Mushroom Substratum, i-HV Truong, kanye nabantu abangu-4 bathola amacala angu-29 ezempilo nokuphepha emsebenzini. ukuphepha kwabasebenzi; ukuhlinzeka abasebenzi ngolwazi, isiqondiso, ukuqeqeshwa kanye nokuqondisa; kanye nokuqinisekisa ukuthi izingozi zezindawo ezivalekile ziyaqedwa noma ziyancishiswa Nokuziphatha okuhlobene nomsebenzi ngendlela ephephile.
Isinqumo ngoNovemba odlule saphetha ngenhlawulo engu-$200,000 ye-A-1 Mushroom Substratum (manje engasenamali), u-$120,000 we-HV Truong, kanye no-$15,000, 10,000, kanye no-$5,000 kulaba abathathu.
U-Raj Chouhan, ongumgxeki wezabasebenzi we-New Democratic Party yase-British Columbia, ungomunye wamakhorasi afuna isigwebo esinzima. U-Chouhan uchaze isijeziso sokugcina njengokushaywa kwesandla. Wabika ukuthi lemindeni inethemba ngempela lokuthola okuthile ukusiza eminye imindeni nezinye izisebenzi kuyo.q
Ukuze kuchazwe izimo eziholele kulesi sigameko esibulalayo, inqubo yokufaka umquba wamakhowe endaweni idinga ukucatshangelwa.Kumodeli wopopayi we-3-D, i-WorkSafeBC iveze ukuthi uhlelo lwamapayipi lwakhiwe ukuze luhlinzeke ngamanzi ahlanzekile futhi lugaye amanzi. kusukela ethangini elikhulu elizimele lamanzi endaweni ebiyelwe.Amanzi axubile abe esempontshwa ngochungechunge lwamapayipi; kuqala emgqonyeni womquba, bese ufafazwa enqwabeni yomquba equkethe utshani, umquba wezinkukhu kanye ne-gypsum yezolimo.
Kodwa-ke, ngenxa yezinkinga zokusebenza kanye nokuncipha kokukhiqizwa komquba, amathangi amanzi nezindawo ezivaliwe zigcwaliswa ngamanzi acutshungulwayo, utshani nodaka. Ukuze kuvinjwe amaphampu namapayipi ukuba angabandi ebusika, ishede lakhiwa ngodonga lokuvikela ngo-2007.
Okunye okubalulekile ukuklanywa nokwakhiwa kohlelo lokujikeleza kwamanzi enqubo, oludonsa amanzi enqubo ukusuka phansi ethangini ukuya epayipini lokungena.Umbiko we-WorkSafeBC uthe lokhu kubangele ukuvinjwa nezimo ze-anaerobic ohlelweni lwamapayipi.
Umbiko waphetha: pNjengoba utshani nodaka kuhlezi phansi ethangini, lezi zinto ezisetshenziswayo nakanjani zizongena epayipini futhi zivimbe ukugeleza kwamanzi noma zakhe ukuvaleka.q
Ngokuhambisana nesidingo esincishisiwe senqubo yamanzi-idolobha laseLangley lavala inqolobane yokwenza umquba ngasekupheleni kuka-2007 ngenxa yokuphulwa kwemithetho-lokhu kusho ukuthi amanzi angena ohlelweni ahlala isikhathi eside, futhi imvamisa yokugeleza ngamapayipi ayancishiswa futhi anda. ithuba, ukukhula kwamanzi kuncipha futhi kusekela umsebenzi we-anaerobic.
Lo mbiko uyachaza: pOkwenza inkinga ibe yimbi nakakhulu ukuntuleka kwendlela yokukhuthaza ukujikeleza nokuxutshwa okufanayo kwanoma yimaphi amanzi anomoya-mpilo angena ethangini [lenqubo] namanzi anqwabelene, udaka nezinto eziqinile ezansi ethangini.”.
U-Les Mackoff, ummeli wabamangalelwa, uthe abanikazi basebenza nalaba bantu nsuku zonke futhi bazizwa kabi ngalokhu okwenzekayo.q
UMackoff wabika ukuthi ngaphambi kwesigameko esibulalayo, umnikazi wayeqashe ochwepheshe futhi wafuna iseluleko sonjiniyela mayelana nendlela yokufaka ama-biofilters ukusiza ukunciphisa amathuba okuba khona kwephunga.Nokho, wabonisa ukuthi "isakhiwo sinephutha. Isikhungo sibhidlike kakhulu.”
U-Neil McManus unguchwepheshe wokuhlanzeka kwezezimboni oqinisekisiwe ovela e-NorthWest Occupational Occupational Health & Safety e-Vancouver. Uthe umbono wakhe wukuthi onjiniyela balawule ukuphepha emsebenzini ngoba “imiklamo yabo idala izimo zokusebenza ezithinta abanye.”
UMcManus uthe ngokusekelwe kokuhlangenwe nakho kwakhe, imisebenzi eminingi yokwenza umquba inamaphampu angaphansi kwamanzi kanye namaphampu akhiphekayo. Wengeza ngokuthi ngaphandle kwalokhu, abantu kuzodingeka bangene “egunjini ukuze balungise iphampu noma okuthile okuyivimbayo.”
UDavid Nguyen, uchwepheshe wezempilo nokuphepha kwezolimo eFarm and Ranch Safety and Health Association (FARSHA) eLangley, eBritish Columbia, uthe lesi sigameko “sivule wonke amehlo kulo mkhakha.” .Nguyen ubike ukuthi uvakashele emsebenzini futhi ubesebenzisana nabaqashi ngemuva kwesigameko ukuthuthukisa impilo nokuphepha okuhlobene nomsebenzi.
Uthe izinkinga zobunjiniyela ziyinkinga, kodwa wengeza ngokuthi ucabanga ukuthi ezinye izintojnjengezinyathelo zokuvimbela uhlolo lwengozi emkhathini, ukuhlonzwa kwezingozi, kanye nokulawulwa kokuchayeka kungasiza ukuvimbela izingozi.
Ukufunda lezi zimpawu kungase futhi kusize ekuvimbeleni.Cishe ezinyangeni ezimbili ngaphambi kwalolo suku olubulalayo, ngoJulayi 15, 2008, iKomidi Lokubuyekeza Imboni Yepulazi LaseBrithani Columbia lathola izikhalazo ezivela kuKhansela Wedolobha uCharlie Fox nomkakhe mayelana nephunga kanye namanzi amoshayo aphuma emsebenzini wokwenza umquba.
Idolobha seliqalile ukuthatha izinyathelo zomthetho, selivala lesi sikhungo okwesibili. Empeleni, ukulalelwa kwenkantolo yesikhalo sesibili kulindeleke ukuba kubanjwe ezinsukwini ezintathu ngemuva kwengozi.
“Inhlekelele yenzeke lapho esazi ukuthi iphunga liphume khona, ngoba ngokuyisisekelo kwakuwumgodi ongamboziwe,” kusho uFox.” Ngokombono wami, inkinga iwukuthi udaka luphuma kamuva futhi luhlale kulenhlabathi enkulu evulekile. amathangi.”
UMcManus wabika ukuthi esikhathini esingaphansi konyaka ngemva kwesigameko saseLangley, wavakashela elinye ipulazi lamakhowe eBritish Columbia, lapho abona khona “indlela yokusebenza” efanayo futhi wathola “ukugxila okuphezulu ngokumangalisayo” esiteshini sokumpompa. "H2S.
“Kufanele sisuke lapho ngokushesha,” ekhumbula.” Ngaphambi koshintsho, iphunga lalinguziro. Ikhala lami langitshela ukuthi kune-H2S lapha, futhi ngabheka nxazonke futhi angizange ngibone izinguquko zokuchaza ukuthi kwenzekani. Kwakuyipompo leyo. Besibona igwebu phansi,” kusho uMcManner.
Ucabange ukuthi “igwebu elintanta ngaphezu koketshezi lingabamba okungenani umkhathi owodwa wokucindezela”, okunye okungase kube i-H2S.” Lolu uhlelo olubambeke kakhulu futhi aluzinzile kakhulu. Ngakho-ke uma ubamba ama-molecule e-H2S ebhamuzeni oketshezini olujiyile, bese usebenzisa amandla athile ahlanzekile kulo futhi uxegise uketshezi, khona-ke ibhamuza linekhambi Elikhishiwe,” esho.” Icala ladlula ngokushesha... Lapho abaphenyi beyothola imbangela yokufa, abatholanga lutho.”
Umbiko we-WorkSafeBCos uthe ngenkathi isikhulu sezomlilo sase-townos silinganisa umoya eshede cishe ngo-5:30 pm, okuqukethwe kwe-hydrogen sulfide kwakuyizingxenye ezingu-36 ngesigidi (ppm) futhi okuqukethwe komoyampilo kungu-15% -phezulu kakhulu futhi iphezulu kakhulu, ngokulandelana. Okuphansi.Ngemuva nje kwemizuzu engu-22, okuqukethwe kwegesi kwehle kwaya ku-6 ppm, futhi okuqukethwe kwe-oxygen evamile kwaba ngu-20.9%.
Lokhu kugxila kuhluke kakhulu ekubalweni kwe-WorkSafeBC ngomhla ka-Januwari 29, 2009 (izinyanga ezinhlanu kamuva), lapho kukhishwa ivalvu futhi kukalwa umoya epayipini lokungenisa elingaphansi kwevalvu.pOkuqukethwe kwe-H2S kudlula 500 ppm (ubuningi bokufunda ku- umqaphi), okubonisa ukuthi izimo ze-anaerobic epayipini zingabangela okuqukethwe kwe-H2S ukuthi kuphakame ngokwanele ukubangela ukuquleka nokufa ngokushesha,q kuphawulwe umbiko wophenyo.
Kungani esinye isisebenzi eshede singasabeli phakathi nemizuzwana embalwa ngemva kokukhishwa kwe-H2S futhi kamuva sashona, kuyilapho esinye sasinda?
“Uma ubheka ukuhlanzeka emsebenzini, akubona bonke abantu abathintwa yizinto ezifanayo ngendlela efanayo,” kuchaza uShirley Gray, uchwepheshe wezokuhlanzeka emsebenzini eMnyangweni Wezabasebenzi Nezemfundo Ephakeme eNova Scotia eHalifax Say.” Kunenqwaba yabantu ababhemayo. Lapho. Akuwona wonke umuntu ozoba nomdlavuza wamaphaphu,” uGrey wenze isibonelo.
Uthe izici ezingase zibe nomthelela ekuphenduleni kokuchayeka zihlanganisa ukungena komoya, ukusondela lapho udedelwa khona, kanye nezinga lokuphefumula.” [Umsebenzi] ubengenza umsebenzi omningi futhi ahlanganiswe ngokugcwele ezindaweni eziningi kunabanye abaseduze kwakhe,” esho. ngaphandle.
UGrey ubika ukuthi wonke amagesi azongena esikhundleni somoya-mpilo, kodwa ukwenza lokhu, ukugxila kufanele kube kuphezulu kakhulu. scavenger, “empeleni ibopha umoya-mpilo futhi iwususe emkhathini.”
UMcManus uthe ku-15% komoyampilo, “ngeke ube nomthelela omubi ekusebenzeni kwabantu.” “Kungakho kungenzeka ukuthi i-H2S yenze lokhu,” kuqagela.
Lokhu kufa kwenze iNew Democrats yaseVancouver kanye neBritish Columbia Federation of Labor (BCFL) ukuthi icele kaningi ukuthi kuphenywe umphenyi wecala.Umphenyi Omkhulu u-Lisa Lapointe waphendula ucingo ngoDisemba nyakenye.
“Ngemva kokubuyekeza lonke ulwazi olutholakala ecaleni, okuhlanganisa nombiko we-WorkSafeBCos, [uLapointe] uphethe ngokuthi kungaba yinzuzo ukwenza uphenyo ukuze kuhlolwe ezinye zezimo ezibanzi zesigameko ukuze kuvinjelwe ukufa esikhathini esizayo ezimeni ezifanayo. "Isitatimende seBritish Columbia Coroner Service, ekomkhulu eVancouver, sithe. Ngesikhathi sophenyo okuhlelwe ukuthi luqale ngoMeyi 7, umphenyi omkhulu uNorm Liebel kanye namajaji bazolalela ubufakazi bofakazi abaningi.
URaj Chouhan weNew Democratic Party uthe uthemba ukuthi ukusikisela okuthile “kungasisiza sigweme izinhlekelele ezinjalo esikhathini esizayo.”
USihlalo we-BCFL uJim Sinclair naye walwamukela uphenyo lwesifundazwe futhi waveza esitatimendeni ukuthi luletha ithemba lokuvikeleka okukhulu kwamapulazi aseBritish Columbia.q
Umbiko we-WorkSafeBC uthe ngaphambi kwesigameko, akekho owayebonakala ekhathazekile mayelana nokuthuthuka okungenzeka kwezimo ze-anaerobic kumapayipi ayingxenye yenqubo yokubuyisela amanzi, ngisho noma lonke uhlelo luhlala lusebenza.q
"Nakuba imboni kanye nama-ejensi alawulayo aqaphela ukuthi ukukhiqizwa kwegesi kungumkhiqizo walokhu kusebenza, izincwadi zembonini zigxile kakhulu ekuvikelweni kwemvelo nokuqedwa kwephunga, kunokuba izingozi ezingase zibe khona ngesikhathi sokukhiqizwa kwala magesi," wanezela umbiko.
U-Scott Fraser, umqondisi wohlelo lwe-FARSHA, uvumile ukuthi ngaphambi kwengozi, izinga lokuqwashisa ngezingozi zokwenziwa komquba wamakhowe lalilinganiselwe. i-sulfide engase ichitheke kulezi zinto,” kusho uFraser.
Ubike ukuthi selokhu kwenzeke lesi sigameko, imininingwane ebhaliwe isatshalaliswa ezindaweni ezifuze lezi, nohlelo lokulawula ukuchayeka komquba wamakhowe selubekiwe.
UNguyen wathi izisebenzi zasefektri yaseLangley zikhuluma isiVietnam, futhi ukhuluma isiVietnam njengolimi lwakhe lwesibili.” Abantu abasebenza [kwezolimo] bavame ukuba yizifiki zesizukulwane sokuqala, ngakho isiNgisi asilona ulimi lwabo lokuqala ngaso sonke isikhathi.”
