M'mawa wa Seputembara 5, 2008, woyimba maula adaitanidwa ku A-1 Mushroom Substratum Ltd. ku Langley, British Columbia. Aka kanali kachiŵiri m’masiku oŵerengeka.Kumeneko, anapeza kuti chitoliro choloŵera m’munsi mwa nyumba yopoperapopopo chinali chotsekeka kotheratu, ndipo anadziwitsa woyang’anira malo opangira manyowa a bowa kuti pakufunika kampani yodziŵa bwino popopera zimbudzi.
M'malo mwake, motsogozedwa ndi woyang'anira, ogwira ntchito awiri anayesa kuchotsa kutsekeka kwa valve ya butterfly mu payipi. M'mphindi zochepa chabe atatsegula flange, wogwira ntchito adagwa pansi chafufumimba m'madzi pansi pa shediyo, omwe amakhulupirira kuti chifukwa cha kutulutsa mwadzidzidzi kwa mpweya wa hydrogen sulfide (H2S) m’malo opanda okosijeni.Adzafa.
M'mphindi zingapo zotsatira, opulumutsa awiri omwe angakhalepo kuchokera ku ntchito yobzala ndi kukonza bowa ambiri adzakhala ndi tsogolo lofanana.Antchito ena awiri-mwamwayi-adzavutika pafupi ndi imfa, kuwonongeka kwa ubongo kosasinthika.
Mu lipoti la kafukufuku lomwe linatulutsidwa kumapeto kwa mwezi wa November, WorkSafeBC idzafotokoza zolephera zingapo pakupanga, kumanga ndi kugwira ntchito kwa malo. ” “Zidzatenga miyezi kuti tiyende madera akuluakulu a malo ogwirira ntchito; zidzatenga miyezi ingapo kuti timvetsetse bwino njira zamafakitale zomwe zikukhudzidwa ndi zomwe zikuchitika mkati mwa zaka zisanu. Kutsatira nthawi ya zochitika ndi zisankho zomwe zimachitika.q
Patsiku limenelo la September, antchito aŵiri anali kuyesa kuchotsa chitoliro chotsekeka m’nyumba yopopera yotsekeka, pamene woyang’anira wawo anali kuyang’ana pamalo otalikirapo pafupifupi mamita atatu kuchokera pakhomo la nyumbayo. Masentimita pansi pa okhetsedwa, anachotsa 8 corrod bolts pa flange ya valavu, ndi momasuka anaika 4 mabawuti atsopano kuti agwire valavu m'malo.
Cha m’ma 5 koloko masana, m’modzi mwa ogwira ntchitowo anagwiritsa ntchito screwdriver kuti atulutse mbali ya pamwamba pa valavu, kenako anagwiritsa ntchito screwdriver ina kuchotsa udzu, matope ndi zinthu zina zotsekera mu valve.” Madzi pang’ono anayamba kutuluka. , "Lipoti lofufuza la WorkSafeBC ku Richmond, British Columbia linati.
Wogwira ntchitoyo atachotsa udzuwo, anadandaula kwa woyang’anira za fungolo, zomwe zinapangitsa woyang’anirayo kulola wantchitoyo kuchoka m’shediyo.
Wogwira ntchito pa valavuyo anatenga sitepe kenako n’kugwa chafufumimba m’madzi ndi m’matope.Woyang’anira anakwera pansi ndi kuthandiza wantchito wachiwiriyo kuchirikiza wantchito wosayankhayo pampando wokhala pafupi ndi khoma la shedi. .
Pamene ogwira ntchito zachipatala anafika cha m’ma 5:20 pm, anapeza kuti woyang’anira kunja kwa shediyo anali atasochera ndipo akuvutika kupuma.” Ogwira ntchito pa ambulansiyo anaona fungo losasangalatsa, ndipo anaganiza kuti kunali koopsa, ndipo anaganiza zochoka m’galimotoyo. malo okhetsedwa, "Idatero WorkSafeBC, kuletsa ogwira ntchito ena omwe adafika ndi makwerero kulowa mu shedi.
Pazonse, ogwira ntchito asanu ochokera m'makampani atatu omwe amapanga malo opangira zinthu - A-1 Mushroom Substratum, HV Truong Ltd. (kampani yolima bowa) ndi Farmers' Fresh Mushrooms Inc. (kampani yolongedza ndi kutsatsa) adachotsedwa mu pogona .Ut Van Tran, 35, Chi Wai Chan, 55, ndi Han Duc Pham, 47, anamwalira; Tchen Phan adakali panjinga ya olumala ndipo Michael Phan ali chikomokere.
Lipoti la WorkSafeBCos lidawonetsa zolakwika zambiri: kusowa kwa dongosolo la OH&S patsamba; kulephera kukonza zinthu za anaerobic (anaerobic) zomwe zimapangidwira mu thanki yomwe imapopera madzi kudzera mupaipi, zomwe zimapangitsa kuti H2S ikhale mu chitoliro cholowera; kusowa chitetezo ku zolimba kulowa mapaipi Engineering amazilamulira; kusowa kutsata malamulo; kusowa kwa kamangidwe, kamangidwe, ndi kagwiritsidwe ntchito ka malo kuyambira 2004.
Mtsogoleri wofufuza za WorkSafeBC Jeff Dolan adati: pTikuzindikira kuti mabanjawa amayenera kudikirira nthawi yayitali kuti adziwe zambiri zomwe zidachitikira okondedwa awo. Zifukwa zikumveka. ”, adatero potulutsa atolankhani.
Mu Ogasiti 2010, A-1 Mushroom Substratum, HV Truong, ndi anthu 4 adalandira milandu 29 yazaumoyo ndi chitetezo pantchito. chitetezo cha ogwira ntchito; kupereka chidziwitso, chitsogozo, maphunziro ndi kuyang'anira ogwira ntchito; ndikuwonetsetsa kuti kuwopsa kwa malo otsekeredwa kuthetsedwa kapena kuchepetsedwa.
Chigamulo cha Novembala chapitacho chinatha ndi chindapusa cha $200,000 pa A-1 Mushroom Substratum (yomwe tsopano yasokonekera), $120,000 ya HV Truong, ndi $15,000, 10,000, ndi $5,000 kwa atatuwo.
Raj Chouhan, wodzudzula chipani cha New Democratic Party ku British Columbia, ndi amodzi mwa oimba omwe akufuna chigamulo chokhwima. Chouhan adalongosola kuti chilango chomaliza chinali kumenya mbama padzanja.

Zofunikanso ndi mapangidwe ndi mapangidwe a njira yoyendetsera madzi, yomwe imakoka madzi kuchokera pansi pa thanki kupita ku chitoliro cholowetsa.
Lipotilo linanena kuti: pPopeza udzu ndi matope zakhazikika pansi pa thanki, zinthuzi zidzalowa m'mipope ndikuletsa kutuluka kwa madzi kapena kupanga kutsekeka.q
Kuphatikizidwa ndi kuchepa kwa kufunikira kwa madzi opangira madzi-tawuni ya Langley inatseka khola la kompositi kumapeto kwa chaka cha 2007 chifukwa cha kuphwanya malamulo - izi zikutanthauza kuti madzi omwe amalowa m'dongosolo amakhala nthawi yayitali, ndipo maulendo akuyenda kudzera mu mapaipi amachepetsedwa ndikuwonjezeka. mwayi, madzi kukula stagnates ndi kuthandiza anaerobic ntchito.
Lipotilo likufotokoza kuti: pChimene chikuwonjezera vutoli ndi kusowa kwa njira zolimbikitsira kuyenda ndi kusakaniza yunifolomu kwa madzi aliwonse okhala ndi okosijeni omwe amalowa mu thanki [yochita] ndi madzi owunjikana, matope ndi zolimba pansi pa thankiyo.”
Les Mackoff, loya woimira milandu, adati eni ake amagwira ntchito ndi anthuwa tsiku lililonse ndipo akumva chisoni ndi zomwe zikuchitika.q
Mackoff adanena kuti chisanachitike chochitika chakupha, mwiniwakeyo adalemba ntchito akatswiri ndipo adapempha uphungu wa uinjiniya momwe angayikitsire ma biofilters kuti achepetse kuthekera kwa fungo. Malowa awonongeka kwambiri. ”
Neil McManus ndi waukhondo wamafakitale wovomerezeka wochokera ku NorthWest Occupational Health & Safety ku Vancouver. Anati malingaliro ake ndi akuti mainjiniya amayang'anira chitetezo pantchito chifukwa "mapangidwe awo amapanga malo ogwirira ntchito omwe amakhudza ena."
McManus adanena kuti kutengera zomwe adakumana nazo, ntchito zambiri za kompositi zimakhala ndi mapampu ocheperako komanso mapampu ochotsamo. Ananenanso kuti popanda izi, anthu amayenera kulowa "mchipindamo kuti akonze mpope kapena china chake chotchinga."

Fox anatsutsa kuti: “Tsokalo linachitika kumene tinkadziŵa kuti fungolo linatuluka, chifukwa kwenikweni linali thanthwe losavundukuka.” M’lingaliro langa,” iye anatero, “vuto ndiloti zinyalalazo zimatuluka pambuyo pake n’kukhala m’matope aakulu otseguka ameneŵa. matanki.”
McManus adanena kuti pasanathe chaka chimodzi kuchokera pamene Langley adachita, adayendera famu ina ya bowa ku British Columbia, komwe adawona "njira yogwiritsira ntchito" yomweyi ndipo adapeza "kuchuluka kwakukulu modabwitsa" pamalo opopera madzi. "H2S.
“Tiyenera kuchoka kumeneko mwamsanga,” iye anakumbukira motero.” Kusinthako kusanachitike, kununkhiza kunali ziro. Mphuno yanga inandiuza kuti pali H2S pano, ndipo ndinayang'ana pozungulira ndipo sindinawone kusintha kulikonse kuti ndifotokoze zomwe zikuchitika. Imeneyo inali mpope. Titha kuwona thovu pansi, "adatero McManner.
Ananenanso kuti "chithovu choyandama pamwamba pa madziwo chimatha kugwira mpweya umodzi wokhazikika", womwe wina ukhoza kukhala H2S. Ndiye ngati mutchera mamolekyu a H2S mu thovu mumadzi okhuthala, ndikuyikapo mphamvu yoyera ndi kumasula madzimadzi, ndiye kuti kuwirako kumakhala ndi yankho Lotulutsidwa, "adatero."

Lipoti la WorkSafeBCos linanena kuti pamene mkulu wa moto wa townos ankayeza mpweya mu shedi pafupifupi 5:30 pm, hydrogen sulfide zili ndi magawo 36 pa miliyoni (ppm) ndipo mpweya unali 15% - wokwera kwambiri komanso wokwera kwambiri, motero. Pakadutsa mphindi 22 zokha, mpweya wa gasi unatsikira ku 6 ppm, ndipo mpweya wabwino unali 20.9%.
Izi zikusiyana kwambiri ndi chiwerengero cha WorkSafeBC pa January 29, 2009 (miyezi isanu pambuyo pake), pamene valavu inachotsedwa ndipo mpweya mu chitoliro cholowera pansi pa valve unayesedwa.pZomwe zili ndi H2S zimadutsa 500 ppm monitor), kusonyeza kuti mikhalidwe ya anaerobic mupaipi ingapangitse zomwe zili mu H2S kukhala zokwera mokwanira kupangitsa chikomokere ndi kufa mwachangu, q lipoti lofufuza lidazindikira.
Kodi nchifukwa ninji wogwira ntchito m’shediyo anakhala wosalabadira mkati mwa masekondi angapo pambuyo pa kutulutsidwa kwa H2S ndipo kenako anamwalira, pamene winayo anapulumuka?
“Mukayang’ana pa ukhondo wa pa ntchito, si onse amene amakhudzidwa ndi zinthu zofanana mofanana,” akufotokoza motero Shirley Gray, waukhondo wa pa ntchito ya Nova Scotia Department of Labor and Higher Education ku Halifax Say.” Pali osuta ambiri. Apo. Sikuti aliyense adzadwala khansa ya m’mapapo,” Grey anapereka chitsanzo.
Anatinso zinthu zomwe zingakhudze momwe angayankhire kukhudzidwa ndi monga mpweya wabwino, kuyandikira mpaka pomwe amamasulidwa, komanso kupuma. ”[Wogwira ntchito] akanatha kugwira ntchito yochulukirapo ndikuphatikizana ndi malo ambiri kuposa ena omwe ali pafupi naye, ”adatero. kunja.
Gray akuti mipweya yonse ilowa m'malo mwa oxygen, koma kuti izi zitheke, kuchuluka kwake kuyenera kukhala kokwera kwambiri. mkangaziwisi, “zimamangadi mpweya ndi kuuchotsa mumlengalenga.”
McManus adanena kuti mu 15% oxygen, "simudzakhala ndi vuto lalikulu pa moyo wa anthu." "Ichi ndichifukwa chake zikutheka kuti H2S idachita izi," adatero.
Imfa zimenezi zinachititsa a New Democrats ku Vancouver ndi British Columbia Federation of Labor (BCFL) kuti aitanitse mobwerezabwereza kufufuza kwa coroner.Chief Coroner Lisa Lapointe adayankha kuitanako mu December chaka chatha.
"Pambuyo powunika zonse zomwe zilipo pamlanduwo, kuphatikiza lipoti la WorkSafeBCos, [Lapointe] adatsimikiza kuti zingakhale zopindulitsa kuchita kafukufuku kuti mufufuze zina mwazochitika zomwe zidachitika kuti apewe kufa kwamtsogolo m'mikhalidwe yofananayo. "Mawu ochokera ku British Columbia Coroner Service, likulu lawo ku Vancouver, adati. Pakafukufuku omwe akuyenera kuyamba pa May 7, mkulu wa coroner Norm Liebel ndi oweruza adzamvetsera umboni kuchokera kwa mboni zambiri.
Raj Chouhan wa New Democratic Party ananena kuti akuyembekeza kuti malingaliro ena “angatithandize kupeŵa masoka otero m’tsogolo.”
Wapampando wa BCFL a Jim Sinclair adalandilanso kafukufuku wachigawochi ndipo adanenanso kuti izi zidabweretsa chiyembekezo chachitetezo chokulirapo m'mafamu aku Britain Columbia.q
Lipoti la WorkSafeBC linanena kuti izi zisanachitike, palibe amene akuwoneka kuti akuda nkhawa ndi zomwe zingachitike pamayendedwe a anaerobic m'mapaipi omwe amapanga gawo la njira yobwezeretsa madzi, ngakhale dongosolo lonselo likadali aerobic.q
"Ngakhale kuti makampani ndi mabungwe olamulira amazindikira kuti kupanga gasi ndizomwe zimachitika chifukwa cha ntchitozi, mabuku amakampaniwa amayang'ana kwambiri chitetezo cha chilengedwe ndi kuthetsa fungo, osati zoopsa zomwe zingapangidwe panthawi yopanga mpweya umenewu," linawonjezera lipotilo.
Scott Fraser, woyang'anira polojekiti ya FARSHA, adavomereza kuti ngoziyi isanachitike, chidziwitso cha kuopsa kwa ntchito yopangira manyowa a bowa chinali chochepa. sulfide yomwe ingachotsedwe kuzinthu izi, "Fraser adatero.
Adanenanso kuti kuyambira pomwe zidachitikazi, zidziwitso zolembedwa zidagawidwa kuzinthu zofananira, ndipo dongosolo loyang'anira mawonekedwe a kompositi ya bowa lakhazikitsidwa.
Nguyen ananena kuti ogwira ntchito pafakitale ya Langley amalankhula Chivietnamu, ndipo amalankhula Chivietnamu monga chinenero chake chachiŵiri.” Anthu amene amagwira ntchito [zaulimi] kaŵirikaŵiri amakhala ochokera m’mibadwo yoyamba, motero Chingelezi si chinenero chawo choyamba.”
