Mangwanani emusi waGunyana 5, 2008, mumwe mupombi akadanwa kuA-1 Mushroom Substratum Ltd. muLangley, British Columbia. Aka kaive kechipiri mukati memazuva mashoma.Ikoko, akaona kuti pombi inopinzwa nechepazasi pepombi yakanga yavharika zvachose, uye akaudza mukuru wepanzvimbo inogadzirwa manyowa ehowa kuti paidiwa kambani ine hunyanzvi hwekupomba tsvina.
Pane kudaro, vachitungamirirwa nemukuru, vashandi vaviri vakaedza kubvisa kuvharika kwevharuvhu yeshavishavi mupombi. Mumasekonzi mashoma ekuvhura flange, mushandi akawira pasi nechiso mumvura pasi peshedhi, anofungidzirwa kuti ndiye. nekuda kwekukurumidza kubuda kwehydrogen sulfide (H2S) gasi munzvimbo isina oxygen.Achafa.
Mumaminitsi mashomanana anotevera, vaviri vanogona kuponesa kubva kune vakawanda-vashandisi mushroom kudyara uye kugadzirisa bhizinesi vachave nemamiriro akafanana.Vamwe vashandi vaviri-nerombo rakanaka-vachatambura pedyo-inouraya, isingagadziriswi kukuvara kwehuropi.
Mumushumo wekuferefeta wakabudiswa pakupera kwaMbudzi, WorkSafeBC icharatidza kukanganisa kwakatevedzana mukugadzira, kuvaka uye kushanda kwenzvimbo.
