Ehlathini lensimbi lezakhiwo zesimanje nezakhiwo zezimboni, izintambo ezingenakubalwa zibophene njengesimiso sezinzwa somzimba womuntu. Lapho umlilo efulethini eliphakeme e-Dubai ngo-2022 ubangela ukusabalala kwamakhebuli avamile, onjiniyela emhlabeni wonke baphinde bagxila kubuchwepheshe obunqanda amalangabi bezintambo. Ingozi eyabangela amashumi ezigidi zamaRandi iye yembula iqiniso elinonya: lapho kubhekene nemililo, izintambo ezivamile ngokuvamile ziba amafuse abulalayo. Izintambo ezivimbela umlilo ziwubuchwepheshe obuyinhloko emkhakheni wokuphepha kagesi, futhi ukubaluleka kwawo akukhona ngaphansi komklamo womlilo wezakhiwo zokwakha. Le ntambo ekhethekile ingagcina isakhiwo esiphelele emalangabini omlilo, inqande ngempumelelo ukusabalala komlilo, futhi ilwele isikhathi esiyigugu sokukhishwa kwabasebenzi kanye nokuhlenga umlilo. “Iwumugqa wokuphila” obaluleke kakhulu ohlelweni lwesimanje lokuvikela ukuphepha. Emkhakheni wezakhiwo eziphakeme kakhulu, ukusetshenziswa kwezintambo ezinqanda ilangabi kuhlobene ngokuqondile nekhono lokuvimbela nokulawula izinhlekelele. Ohlelweni lokuphakelwa kwamandla e-Shanghai Central Building, zonke izintambo ezime mpo zisebenzisa izinga lokubuyiswa komlilo le-Class B1, futhi ikhebula lemitha ngalinye liqukethe okungaphezu kuka-300g kwesigcwalisi esingaphili somlilo esingaphili. Lo mklamo uvumela i-shaft yezintambo ezinezitezi ezingu-20 ukusabalalisa isivinini sokusabalala komlilo ku-1/5 yesakhiwo esivamile ekuhlolweni komlilo okufanisiwe. Ikhebula le-fiber retardant optical elisetshenziswa esakhiweni esihlakaniphile, impahla yalo ekhethekile ye-sheath izokhipha amagwebu futhi yandise lapho ivutha, yenze isendlalelo sokushisa esishisayo esinobubanzi obuphindwe izikhathi ezingu-3 kunosayizi wangempela, ivikela ngokuphumelelayo i-fiber optical yangaphakathi ukuthi ingalimazi. Isistimu yezokuthutha ngojantshi inezidingo eziqine kakhulu zokusebenza kwamakhebuli angavimbeli ilangabi. Ikhebula elicisha ilangabi elisetshenziswa emhubheni wesitimela esihamba ngaphansi komhlaba kufanele liqinisekiswe i-HL3 ngokwezinga le-EN 45545-2, okusho ukuthi uma ikhebula lishiswa ilangabi elingu-800 °C, ukuminyana kwentuthu akudluli ku-0.5m²/s ngomzuzu. I-Siemens, eJalimane, yakha ngokukhethekile ikhebula elikhethekile elicisha ilangabi lomzila ongaphansi komhlaba waseMunich. Yamukela isakhiwo sokugoqa sebhande le-mica elinezingqimba ezimbili. Ekuhlolweni kokuvutha, ukukhanya kwegesi ye-flue bekulokhu kuhlala ngaphezu kwama-80%, okuthuthukisa kakhulu ukubonakala endaweni yomhubhe.
