Izinhlelo ze-Self-Contained Breathing Apparatus (SCBA) sekuyisikhathi eside zifana nokucisha umlilo, okuhlinzeka ngokuvikelwa kokuphefumula okubalulekile ezindaweni ezigcwele intuthu. Kodwa-ke, ukusetshenziswa kobuchwepheshe be-SCBA kudlulela ngalé kwendawo yokucisha umlilo. Lezi zinhlelo eziyinkimbinkimbi zidlala indima ebalulekile ezimbonini nasezimeni ezihlukahlukene, ziqinisekisa ukuphepha lapho umoya ophefumulayo usengozini. Lesi sihloko sihlola ukusetshenziswa okuhlukahlukene kobuchwepheshe be-SCBA, igcizelela ukubaluleka kwayo emikhakheni ehlukene.
Izicelo zezimboni
Ezimeni zezimboni, ikakhulukazi ezimbonini ezikhiqiza amakhemikhali, izindawo ezihluzwayo, nezimboni zemithi, abasebenzi bavame ukuchayeka ezintweni eziyingozi. Izinhlelo ze-SCBA zibalulekile kulezi zindawo, zinikeza isivikelo kumagesi anobuthi, umusi, nezinhlayiya. Baqinisekisa ukuthi abasebenzi bangenza imisebenzi yabo ngokuphepha, ngisho nalapho bekhishwa ngephutha noma ngesikhathi semisebenzi yokunakekela evamile engase iphazamise izinto eziyingozi.
Impendulo Yezinto Eziyingozi
Amaqembu okuphendula izimo eziphuthumayo anikezwe umsebenzi wokuphatha izehlakalo zezinto eziyingozi (HazMat) athembele ezinhlelweni ze-SCBA ukuze avikeleke ezinsongweni eziningi zamakhemikhali, zebhayoloji, ngemisebe, kanye nezenuzi. Ukuthi kusabela ezingozini zezimboni, izigameko zezokuthutha ezibandakanya izimpahla eziyingozi, noma izenzo zobuphekula, ubuchwepheshe be-SCBA bubalulekile ekuqinisekiseni ukuphepha kwabaphenduli bokuqala njengoba bequkethe ubungozi futhi banciphise umthelela wabo emphakathini nasemvelweni.
Ukuhlenga Kwesikhala Esivaliwe
Ubuchwepheshe be-SCBA bubalulekile emisebenzini yokuhlenga esikhaleni esivalekile. Izikhala ezivalekile, njengamathangi, izisele, imisele yendle, namahubhe, zinganqwabelana amagesi anobuthi noma zibe nomoya-mpilo ongenawo umoya-mpilo. Amaqembu abatakuli ahlome ngezinhlelo ze-SCBA angangena ngokuphephile kulezi zindawo ukuze enze imisebenzi yokuhlenga nokuhlenga, avikele abatakuli kanye nalabo abahlengwayo.
Imisebenzi Yezimayini
Imboni yezimayini ibeka izinselelo eziyingqayizivele zokuphefumula ngenxa yokuba khona kothuli, amagesi, kanye namazinga omoya-mpilo ancishisiwe ngaphansi komhlaba. Izinhlelo ze-SCBA zinikeza abavukuzi umthombo onokwethenjelwa womoya ophefumulayo, ikakhulukazi ngesikhathi sezimo eziphuthumayo njengokuwa kwemayini noma umlilo, ukuqinisekisa ukuthi banokuvikeleka okudingekayo ukuze babaleke noma batakulwe.
Izicelo Zasolwandle Nezase-Offshore
Emikhakheni kawoyela negesi yasolwandle neyasogwini, amasistimu e-SCBA abalulekile ekulweni nemililo yangaphakathi kanye nokubhekana nokuvuza kwegesi. Uma kubhekwa imvelo engayodwa yemikhumbi nezinkundla, ukufinyelela ngokushesha kubuchwepheshe be-SCBA kubalulekile ukuze uphile kuze kufike usizo lwangaphandle.
Iqhaza likaI-Carbon Fiber Cylinders
Ingxenye ebalulekile yezinhlelo ze-SCBA isilinda somoya, esigcina umoya ocindezelwe ophefumulelwe umsebenzisi. Intuthuko yakamuva ibone ukwamukelwa kweisilinda esiyinhlanganisela ye-carbon fibres, alula kakhulu kunensimbi yendabuko noma amasilinda e-aluminium. Lokhu kwehliswa kwesisindo, okuvame ukuba ngaphezu kuka-50%, kuyisibusiso kubasebenzisi abadinga ukuhlala beshesha futhi beselula ngenkathi begqoke imishini ye-SCBA. Ukuqina nokuphepha kwalezii-carbon fibre cylinders, kuhambisana nempilo yabo yesevisi enwetshiwe efinyelela eminyakeni eyi-15, ibenza babe ukukhetha okuhle kwezicelo ze-SCBA kuzo zonke izimboni ezihlukahlukene.
Ukuqeqeshwa Nokulingiswa
Ukusetshenziswa okusebenzayo kwe-SCBA kudinga ukuqeqeshwa okuqinile ukuze kuqinisekiswe ukuthi abasebenzisi banganikela futhi basebenzise okokusebenza ngokuzethemba nangempumelelo. Izinhlangano eziningi zitshala imali ezinhlelweni zokuqeqesha kanye nokuzivocavoca ukuze zilungiselele abasebenzi bazo izimo zempilo yangempela. Lokhu akugcini nje ngokuthuthukisa ukuphepha kodwa futhi kuqinisekisa ukuthi abantu bangasebenzisa ngokugcwele amakhono okuvikela ahlinzekwa ubuchwepheshe be-SCBA.
Intuthuko Yekusasa
Njengoba izimboni zithuthuka futhi kuvela izinselelo ezintsha, ubuchwepheshe be-SCBA buyaqhubeka nokuthuthuka. Abakhiqizi bagxile ekuthuthukiseni i-ergonomics, umthamo, kanye namakhono okuqapha wezinhlelo ze-SCBA. Izinto ezintsha ezifana nemishini yokuxhumana edidiyelwe, izibonisi ezihamba phambili, kanye nokuqapha komoya ngesikhathi sangempela kuthuthukisa ukusebenza nokuphepha kwamayunithi e-SCBA, kunweba izinhlelo zabo zokusebenza nakakhulu.
Isiphetho
Ubuchwepheshe be-SCBA buyindlela yokuphila ezindaweni lapho ikhwalithi yomoya ingenakuqinisekiswa khona. Ngaphandle kokucisha umlilo, ukusetshenziswa kwayo kuhlanganisa ukukhiqizwa kwezimboni, ukuphendula kwempahla eyingozi, ukusebenza kwendawo evalekile, izimayini, imisebenzi yasolwandle neyasogwini, nokunye. Ukufakwa kweisilinda esiyinhlanganisela ye-carbon fibreukungena kumasistimu e-SCBA kuphawula intuthuko enkulu, enikeza abasebenzisi ukuphepha okuthuthukisiwe, ukunethezeka, nokusebenza. Njengoba sibheke esikhathini esizayo, ukuqamba okusha okuqhubekayo kubuchwepheshe be-SCBA kuthembisa ukwandisa indima yayo ekuvikeleni izimpilo emikhakheni ehlukahlukene nakakhulu.
