Igiya lokuphefumula elicisha umlilo lidlala indima ebalulekile ekuvikeleni abaphenduli bokuqala ezindaweni ezigcwele intuthu, amagesi anobuthi, nomoya ongenawo umoya-mpilo. I-Self-Contained Breathing Apparatus (SCBA) iyigiya elijwayelekile lezimo ezinjalo. Ukuqinisekisa ukwethembeka kwesikhathi eside kwemishini ye-SCBA akuyona nje imfuneko yokuphepha kodwa futhi kuyisidingo esingokoqobo semisebenzi yansuku zonke yokucisha umlilo. Lesi sihloko sichaza indlela yokulondoloza kahle igiya lokuphefumula lezicishamlilo, ikakhulukazi ngokugxila ekunakekelweni nasekunakekeleniisilinda esiyinhlanganisela ye-carbon fibers, osekuvame kakhulu kumayunithi esimanje e-SCBA.
1. Ukuqonda Izingxenye
Ngaphambi kokuxoxa ngesondlo, kubalulekile ukuqonda izingxenye ezibalulekile zegiya le-SCBA:
- I-facepiece (imaski): Ihlinzeka ngendawo evaliwe ezungeze ubuso bosicishamlilo.
- Isilawuli kanye ne-valve yokufuna: Ilawula ukugeleza komoya ophefumulayo.
- Ukubopha kanye ne-backplate: Ibamba ngokuphephile okokusebenza emzimbeni wesicishamlilo.
- Isilinda somoya esiyinhlanganisela ye-carbon fibre: Igcina umoya ophefumulayo ocindezelweyo, ngokuvamile kubha engu-300 (cishe i-4,350 psi).
- Isilinganiso somfutho kanye nama-alamu: Siza ukuqapha umoya osele.
Ngayinye yalezi zingxenye kufanele isebenze ngendlela efanele, kodwa isilinda sidinga ukunakwa okukhethekile ngenxa yokucindezela okukhulu okuhilelekile kanye nendima yayo ebalulekile ekuqinisekiseni umoya ongaphazamiseki.hlinzeka.
2. KunganiI-Carbon Fiber Cylinders?
Isilinda esiyinhlanganisela ye-carbon fibres asetshenziswa kabanzi kumayunithi e-SCBA namuhla ngezizathu ezimbalwa:
- Engasindi: Alula kakhulu kunamasilinda ensimbi endabuko, anciphisa ukukhathala.
- Isilinganiso esiphezulu samandla nesisindo: Aqukethe ngokuphephile umoya onomfutho ophezulu ngaphandle kokwengeza inqwaba engadingekile.
- Ukumelana nokugqwala: Izinto eziyinhlanganisela ezisetshenzisiwe azijwayele ukugqwala uma ziqhathaniswa nensimbi, okuzenza zilungele izindawo ezinomswakama noma ezimanzi.
Nakuba lezi zinzuzo zicacile,i-carbon fibre cylinders futhi zidinga ukunakekelwa okuqondile ukuze kugcinwe ukusebenza nokuphepha ngokuhamba kwesikhathi.
3. Ukusetshenziswa Kwansuku zonke Nokuhlola Okubonwayo
Njalo uma isicishamlilo siqeda ukusebenzisa i-SCBA, ukuhlola okuyisisekelo kufanele kulandele:
- Bheka umonakalo: Bheka imihuzuko ejulile, ama-dent, noma ama-gouges endaweni yesilinda. I-surface scuffs encane ingase yamukeleke, kodwa noma yini ejulile ingase iphazamise ubuqotho besakhiwo.
- Hlola ukuhlangana kwe-valve: Qinisekisa ukuthi i-valve ijika kahle futhi ayinayo imfucumfucu.
- Hlola ingcindezi: Amasilinda kufanele agcwaliswe kabusha uma ingcindezi yehla ngaphansi kwamazinga okusebenza aphephile, ngokuvamile angu-90% womthamo ogcwele.
Ukunaka kwansuku zonke kuvimbela izinkinga ezincane ekubeni yingozi enkulu.
4. Ukugcinwa Okuhleliwe Nokuhlolwa
Ngaphezu kokuhlolwa kwansuku zonke, ukunakekelwa ngezikhathi ezithile kuyadingeka. Ishejuli evamile ihlanganisa:
- Ukuhlolwa kwe-Hydrostatic: Kudingeka njalo eminyakeni emi-5 (noma ngokwemithetho yendawo ngayinye). Lokhu kuhlolwa kwengcindezi kuqinisekisa ukuthi isilinda sisakwazi ukubamba ngokuphephile ukucindezela kwayo okulinganiselwe.
- Ukuhlola okugcwele okubonakalayo: Ngokuvamile kwenziwa minyaka yonke nguchwepheshe oqeqeshiwe. Lokhu kuhlanganisa ukuhlola i-delamination, imicu eveziwe, kanye nezimpawu zokucindezelwa ngokweqile.
- Ukuseviswa kwe-valve: Imicu nama-seal kufanele kuhlolwe futhi kugcotshwe njengoba kudingeka ukuze kuvinjelwe ukuvuza.
Konke ukuhlolwa nokunakekelwa kufanele kurekhodwe ukuze kulandeleke futhi kuthotshelwe.
5. Izimo Zokugcina
Ukuthi igiya ligcinwa kanjani futhi kuphi kuthinta kakhulu impilo yalo:
- Gwema ukukhanya kwelanga okuqondile: Imisebe ye-UV ingehlisa ungqimba lwangaphandle lwamasilinda ayinhlanganisela ngokuhamba kwesikhathi.
- Ukulawula izinga lokushisa: Amazinga okushisa aphakeme, ikakhulukazi ukushisa, angenza buthaka inhlaka ebamba imicu yekhabhoni endaweni yayo.
- Gcina yomile futhi ihlanzekile: Umswakama nokungcola kungabangela ukugqwala ezingxenyeni zevalvu futhi kulimaze izendlalelo eziyinhlanganisela uma zingahlanzwa njalo.
Sebenzisa okokukhweza odongeni noma amakhompathimenti anikezelwe ukuze ugcine amagiya e-SCBA aqondile naphansi.
6. Imikhuba Ephephile Yokugcwalisa Kabusha
I-carbon fibre cylinders kufanele njalo igcwaliswe ngabasebenzi abaqeqeshiwe besebenzisa imishini eqinisekisiwe:
- Sebenzisa umoya wokuphefumula ohlanzekile, owomile: Ukungcola kungalimaza kokubili ingaphakathi lesilinda futhi kulimaze umsebenzisi.
- Gwema ukugcwala ngokweqile: Gcwalisa njalo ingcindezi eshiwo ngumkhiqizi, ngokuvamile amabha angu-300. Ukucindezela ngokweqile kungaholela ekuhlulekeni okuyingozi.
- Vumela ukupholisa: Umoya uyafudumala ngesikhathi sokucindezelwa. Lindela ukuthi liphole ngaphambi kokuhlola ukucindezela kokugcina.
7. I-Cylinder Lifespan kanye Nomhlalaphansi
Iningii-carbon fibre cylinders abe nempilo yesevisi yeminyaka eyi-15, kuye ngokusetshenziswa nesimo. Ngemuva kwalesi sikhathi, kufanele zikhishwe emsebenzini futhi zilahlwe kahle noma zigaywe kabusha. Ngisho noma ingaphandle libonakala lilihle, ingcindezi yangaphakathi ngokuhamba kwesikhathi ingase ibeke ukuphepha engozini.
8. Ukuqeqeshwa Nokuqwashisa
Bonke abasebenzi bokucima umlilo kufanele baqeqeshwe ekunakekeleni okuyisisekelo kwegiya le-SCBA, ikakhulukazi ukuthi zitholwa kanjani izimpawu eziyisixwayiso zokuguga kwamasilinda noma umonakalo. Ukuqeqeshwa okuvamile kuqinisekisa ukuthi wonke umuntu angaba neqhaza ekutholakaleni kusenesikhathi kwezinkinga nasekuphathweni okuphephile kwezingxenye ezinomfutho ophezulu.
Isiphetho
Ukugcina izinto zokuphefumula ezicisha umlilo kuwumthwalo ohlanganyelwe. Yize zonke izingxenye zamayunithi e-SCBA zidinga ukunakwa,isilinda esiyinhlanganisela ye-carbon fibers zidinga ukuphathwa okukhethekile ngenxa yezinto zazo, umsebenzi, namazinga okucindezela. Ngokuhlolwa kwansuku zonke, isitoreji esifanele, isevisi evamile, nokuqonda imingcele yabo yokusebenza, lawa ma-cylinders anganikeza ukwesekwa okuthembekile, okukhanyayo kubacimi bomlilo iminyaka eminingi. Ukubeka kuqala lezi zinqubo zokunakekela akuqinisekisi impilo ende yemishini kuphela kodwa okubaluleke kakhulu, ukuphepha kwalabo abathembele kuzo ezindaweni ezinobungozi obukhulu.
