Izicishamlilo eziphefumulayo ezinothando: Yini i-SCBA?

Esimweni somlilo ovuthayo noma indawo yengozi yezimboni egcwele amagesi amabi, izicishamlilo kanye nezisebenzi zezimboni zikhokhisa ngokungesabi phambili, zibeke umthwalo osindayo wokuvikela impilo nempahla. Kulezi zindawo eziyingozi kakhulu, kunohlobo lwemishini efana 'ne-Life Shield yabo', okungukuthi, izinto zokuphefumula ezinazo zokuphefumula (i-SCBA). Kuyini ngempela, futhi ube naluphi ulwazi olusebenzayo nezinsizakusebenza zesicelo? Okulandelayo, ake sihlole ngokujulile.

Yini i-SCBA: Ukuchazwa kanye Nesimiso?

I-applatus ephefumula okuqukethwe okuqukethwe (i-SCBA), eyaziwa nangokuthi i-SCBA ye-Open-Circuit Rescue noma kwesinye isikhathi ibizwa ngokuthi yi-app app abkatus ecindezelwe (Caba) noma umane nje yokuphefumula (i-BA), okuyithuluzi eligqokwa ukuhlinzeka ngomoya ophefumulayo Esimweni esingengozi maduze empilweni noma empilweni. Ngokuvamile asetshenziswa ekucimeni umlilo nasembonini.
I-SCBA iyi-applatus evulekile yokuphefumula yezimboni egcwele i-oksijini emsulwa, kepha ngomoya ocindezelwe ohlungwa kahle. Lo mklamo unenzuzo eyingqayizivele yokukwazi ukuzivumelanisa nezimo ezihlangeni eziningi eziyinkimbinkimbi neziyingozi. 'Ukuzimela' kuyinto ebalulekile, okusho ukuthi akudingi ukuthembela ekuhlinzekeni okukude kwegesi yokuphefumula, njenge-hose ende ukuthola umoya. Umsebenzisi ukhululekile ukuzungeza indawo eyingozi engafakwanga umugqa we-hose, ukuthuthukisa kakhulu ukuhamba nokuphepha.

Izakhi ezibalulekile ze-SCBA

Imaski yobuso ephelele

Imaski yobuso ephelele iyisithiyo sokuqala phakathi komsebenzisi nendawo eyingozi. Kwenziwa kusuka ku-delilient kakhulu, impahla elwa nenkunkuma efanelana nobuso, ukuvimba ngempumelelo izinhlayiya eziyingozi, amagesi kanye nomucu. Ngasikhathi sinye, insimu enkulu yokwakhiwa kombono wemaskhi ivumela umsebenzisi ukuthi abe nomkhakha ocacile wombono, ngisho nasendaweni egcwele intuthu, ukuqinisekisa ukuphepha kokunyakaza.

Umsilawu

Umlawuli 'ubuchopho obuhlakaniphile' be-SCBA, obungakwazi ukulawula kahle ukugeleza komoya nengcindezi. Kungakhathalekile ukuthi unesimo sokusebenza somsebenzisi, kungaba sokunyakaza okunzima noma okujwayelekile, umlawuli uqinisekisa isipiliyoni sokuphefumula esizinzile futhi esinethezekile, evumela umsebenzisi ukuthi asebenze ngokukhululeka ezindaweni eziyingozi.

Ama-Cylinders Air

Ama-Cylinders Air angenye yezinto eziyinhloko ze-SCBA futhi ayatholakala ngosayizi abangu-4 balitha, abangu-6 bama-6.8 balitha. Ubukhulu obuhlukahlukene bama-chirlinders omoya balungele izimo ezihlukile. Isibonelo, isilinda esingu-4-litre sincanyana futhi silula, okwenza silungele ukusebenza kwesikhashana noma sibe yi-back-litre yokuphunyuka, kanti isilinda se-litre engu-6.8-litre sinamandla amakhulu okugcina ukuze asindise noma umthamo oyinkimbinkimbi. Lawa masilinda ajwayele ukwenziwa ezintweni ezinamandla aphezulu njenge-carbon fiber, eqinisekisa ukuphepha ngenkathi ugcina isisindo esiphansi ngangokunokwenzeka.

Ingcindezi Gaugis

Ingcindezi yama-Gauges ifaka ama-cylinder Pressure ama-gauges nama-gauges akude. Ama-cylinderrinder Pressure Gauges anika umsebenzisi isibonakaliso sangempela sokuthi ungashiywa umoya ongakanani kwisilinda ukuze kuhlelwe ngokufanele. Ama-Gaesses Remoc ama-Gareses aqhele, ikakhulukazi amamodeli ane-PASD ahlanganisiwe (amadivaysi ahlanzekile wokuqwashisa), agxeka ngokwengeziwe. Uma umsebenzisi asamile endaweni eyingozi, idivaysi yokudlula izokhala nge-alamu, ixwayise abalingani beqembu ukuthi baqale ukutakulwa, bengeza ngokuvikela okunamandla empilweni yomsebenzisi.

Ephethe intambo

I-Backpack yenzelwe imichilo ehlombe eguqukayo kanye nebhande lesinqe, elingashintshwa kalula ngokuya ngesimo somzimba womsebenzisi. Ngale ndlela, i-SCBA ingathwalwa ngokuqinile emzimbeni womsebenzisi, futhi ngeke ikhathele kakhulu lapho igqoka isikhathi eside, iqinisekise ukuthi umsebenzisi angagcina isimo esihle lapho enza imisebenzi.

Izinhlobo Zama-Respirators kanye nokuhlukaniswa kwe-SCBAS

Ukuhlanza umoya wokuhlanza izindiza (APRS)

Ama-respirators ahlanza umoya (APRS) aklanyelwe ukususa okungcola kwendiza ngokuhlunga. Kuqukethe ama-respirators ahlanganisiwe, ahlunga ngempumelelo izinhlayiya ezinomoya onjengothuli, impova, njll., Kanye nokuhlanza umoya okuhlanza umoya ngama-cartridges Lezi zimophi zivame ukusetshenziswa ezindaweni ezingcoliswe kancane futhi zivame kakhulu empilweni yansuku zonke kanye nezimo zomsebenzi ezinobungozi obuphansi.

Ama-Air Supply Respirators (ASRS)

Ama-respirators ahlinzekwa umoya (ASRS) ahlinzeke umoya ohlanzekile emthonjeni ohlukile. Bahlinzeka ngohlu oluphelele lokuvikelwa ekwanzweni okuhlukahlukene, kufaka phakathi ama-concleates, amagesi kanye namakhaza, futhi babambe iqhaza elibalulekile ezindaweni ezimpofu ze-oxygen. I-SCBAS uhlobo olulodwa lwe-ASRS futhi idlala indima ebalulekile ekusongelweni ngokushesha kwezempilo nasempilweni (IDLH) izindawo kanye nokuphendula okuphuthumayo.

Ukwephulwa kwe-SCBA

• Escape SCBAS: Ukuphunyuka kwe-SCBAS ekhona ngokuyinhloko njengemishini yokusekela emuva. Kwezinye izindawo zokusebenza, ukuvikelwa kwe-SCBA kungenzeka kungadingeki ekungeneni kokuqala, kepha kungaba wusizo emcimbini wesimo esiphuthumayo. Lawa ma-SCBAs ajwayele ukwakhelwa i-airflow eqhubekayo futhi afakwe nge-hood elula engadonswa ngokushesha ngesikhathi esifushane. I-SCBAS futhi ibalulekile njengesipele esiphuthumayo lapho usebenzisa i-Class A noma B Amakhemikhali Amakhemikhali futhi ancike ekucindezelekeni okuhle kokuphefumula.
• Ku- Out SCBA: I- Out SCBA ukukhetha okungcono kakhulu uma kucacile ukuthi isisebenzi sidinga ukuvikelwa kwe-SCBA usuku lonke. Ingasetshenziswa kwimodi yokujikeleza evulekile noma evaliwe, futhi imvamisa inokuhlinzekelwa komoya okukhulu kwezikhathi ezinde, zomsebenzi ezinamandla.

Izindlela zokuqapha ukusetshenziswa kwe-SCBA

Izidingo zokuhlushwa kwe-oksijini

Kubalulekile ukuqaphela ukuthi ngokungafani nemidlalo yokuphefumula yokuphefumula ye-oksijini yokuphefumula ebonakalayo, i-SCBA ingasetshenziswa kuphela endaweni lapho okuhlushwa umoya-mpilo emoyeni kungaphansi kuka-17%. Lapho ukubonwa komoya-mpilo kuwele ngaphansi kwaleli Zinga, umsebenzisi angabhekana nengozi ye-asphyxiation. Ngakho-ke, ngaphambi kokungena endaweni enobungozi, kubalulekile ukubheka ngokucophelela okuqukethwe komoya-mpilo kwesiza.

Izici Zodwa Ezisetshenzisiwe

Izinsimbi zokuphefumula ezihlungiwe zokuzikhulula ziwumkhiqizo olahlwayo futhi ukusetshenziswa kabusha akuvunyelwe ngokuphelele. Ukusetshenziswa okuphindaphindiwe kungahle kuholele ekunciphiseni okukhulu emthethweni we-Filtration kanye nokuvinjwa okungaphumeleli kwamagesi ayingozi, ngakho-ke kusongela kakhulu impilo yomsebenzisi.
Imininingwane yokuvikelwa komuntu siqu
Abasebenzisi abanezinwele ezinde kufanele bagqoke njalo i-SCBA ngayo yonke izinwele zabo eziboshwe ngaphakathi kwe-hood. Lokhu kungenxa yokuthi amagesi anobuthi angangena kwi-hood ngezinwele futhi alimaze umsebenzisi, ngakho-ke kubalulekile ukuthatha le mininingwane.

Okubalulekile kokugqoka imaskhi

Lapho ugqoke imaski yesigamu, kubalulekile ukuthi uqiniseke ukuthi imaskhi ifanela ngokungenantambo phezu komlomo nekhala, nokuthi ifanelana nobuso obungenamsoco. Kuphela ngokuqinisekisa ukuthi umoya omuhle ungakuvimba ngempumelelo ukungenelela kwamagesi ayingozi futhi unikeze ukuvikela okuthembekile komsebenzisi.
Kulula ukugqoka izibuko
Ngokwezikhakha zombukiso, i-SCBA ingasetshenziswa ngaphandle kwesidingo sokususa izibukeli zayo, futhi i-SCBA yenzelwe lokhu engqondweni, ngaphandle kokuyekethisa isivikelo esiphelele noma esibangela noma yikuphi ukuphazamiseka okwengeziwe kumsebenzisi.

Kungani ukhetha uJiu Pai SCBA?

I-Jiupai inikezelwe ekukhiqizeni okuphezulu - amayunithi we-notch SCBA. Sisebenzisa izinto eziphakeme kakhulu - Ikhwalithi yekhwalithi ukuqinisekisa ukuqina kanye nokwethenjwa kwayo yonke ingxenye. Ama-Cylinders Air enziwe ngezinto ezithuthukisiwe, enikeza umthamo wokugcina umoya onamandla ngenkathi engasindi. Obalawuli bethu ngokunemba - bezokwenziwa ukuletha ukuhamba komoya okungaguquki nokuphephile.
I-SCBAS yethu ihambisana nawo wonke amazinga afanele okuphepha, ikunikeza ukuthula kwengqondo okusebenzisayo umkhiqizo ohlangabezana nezidingo ezisezingeni eliphakeme kakhulu. Noma ngabe ungumnyango wokucisha izicishamlilo ufuna ukuvikela abaphenduli bakho abanesibindi noma indawo yezimboni okuhlose ukugcina abasebenzi bakho bephephile, imikhiqizo yethu ye-SCBA ingukhetho oluhle.
Musa ukuyekethisa ukuphepha. Tshala imali ku-SCBA yethu namhlanje futhi uqinisekise indawo ephephile yokusebenza yawo wonke umuntu.
