Ukuqonda Umehluko Phakathi kwe-EEBD ne-SCBA: Izinsiza Ezibalulekile Zokusindisa Ukuphila

Uma kukhulunywa ngemishini yokuphepha yomuntu siqu ezindaweni eziyingozi, amadivayisi amabili abaluleke kakhulu i-Emergency Escape Breathing Device (EEBD) kanye ne-Self-Contained Breathing Apparatus (SCBA). Nakuba zombili zibalulekile ekunikezeni umoya ophefumulayo ezimeni eziyingozi, zinezinjongo ezihlukile, imiklamo, nezinhlelo zokusebenza, ikakhulukazi ngokwesikhathi, ukuhamba, kanye nesakhiwo. Ingxenye ebalulekile kuma-EEBDs esimanje kanye nama-SCBA yiisilinda esiyinhlanganisela ye-carbon fiber, okunikeza izinzuzo ngokuqina, isisindo, namandla. Lesi sihloko singena phakathi komehluko phakathi kwezinhlelo ze-EEBD ne-SCBA, ngokugcizelela ngokukhethekile indimai-carbon fibre cylinders ekulungiseleleni lawa madivaysi ezimo eziphuthumayo nezokuhlenga.

Iyini i-EEBD?

An I-Emergency Escape Breathing Device (EEBD)iyithuluzi lokuphefumula lesikhashana, eliphathekayo eliklanyelwe ngokukhethekile ukusiza abantu ukuba babaleke ezimeni ezisongela ukuphila njengamagumbi agcwele intuthu, ukuvuza kwegesi eyingozi, noma ezinye izikhala ezivalekile lapho umoya ophefumulayo usengozini. Ama-EEBD avame ukusetshenziswa emikhunjini, ezikhungweni zezimboni, nasezindaweni ezivalekile lapho kungase kudingeke khona ukuphuma ngokushesha.

Izimpawu ezisemqoka zama-EEBDs:

1. Inhloso: Ama-EEBD enzelwe ukubaleka kuphela hhayi imisebenzi yokuhlenga noma yokucisha umlilo. Umsebenzi wabo oyinhloko ukuhlinzeka ngenani elilinganiselwe lomoya ophefumulayo ukuvumela umuntu ukuba aphume endaweni eyingozi.
2. Ubude besikhathi: Ngokuvamile, ama-EEBD ahlinzeka ngomoya ophefumulayo imizuzu engu-10-15, owanele ukukhishwa kwebanga elifushane. Azihloselwe ukusetshenziswa isikhathi eside noma ukuhlenga okuyinkimbinkimbi.
3. Idizayini: Ama-EEBD alula, ahlangene, futhi ngokuvamile asebenziseka kalula. Zivame ukuza nesifihla-buso esilula noma ihood kanye nesilinda esincane esinikeza umoya ocindezelwe.
4. Ukunikezwa Komoya: Ii-carbon fiber composite cylinder esetshenziswa kwamanye ama-EEBD ngokuvamile iklanyelwe ukuletha umoya ophansi wokucindezela ukuze kugcinwe usayizi ohlangene nesisindo. Kugxilwe ekuphathekeni esikhundleni sobude besikhathi esinwetshiwe.

Iyini i-SCBA?

A I-Self-Contained Breathing Apparatus (SCBA)iyithuluzi lokuphefumula eliyinkimbinkimbi futhi elihlala isikhathi eside elisetshenziswa ikakhulukazi izicishamlilo, amaqembu abatakuli, nabasebenzi bezimboni abasebenza ezindaweni eziyingozi isikhathi eside. Ama-SCBA aklanyelwe ukunikeza ukuvikeleka kokuphefumula ngesikhathi semishini yokuhlenga, izicishamlilo, nezimo ezidinga ukuthi abantu ngabanye bahlale endaweni eyingozi isikhathi eside kunamaminithi ambalwa.

Izimpawu ezisemqoka zama-SCBAs:

1. Inhloso: Ama-SCBA akhelwe ukuhlenga okusebenzayo kanye nokucisha umlilo, okuvumela abasebenzisi ukuthi bangene futhi basebenze ngaphakathi kwendawo eyingozi isikhathi esibalulekile.
2. Ubude besikhathi: Ama-SCBA ngokuvamile ahlinzeka ngobude besikhathi eside somoya owuphefumulayo, kusukela kumaminithi angu-30 kuya ngaphezu kwehora, kuye ngosayizi wesilinda namandla omoya.
3. Idizayini: I-SCBA iqine kakhulu futhi ifaka imaski yobuso evikelekile, ai-carbon fibre air cylinder, isilawuli sokucindezela, futhi ngezinye izikhathi idivayisi yokuqapha ukulandelela amazinga omoya.
4. Ukunikezwa Komoya: Iisilinda esiyinhlanganisela ye-carbon fiberku-SCBA ingakwazi ukusekela izingcindezi eziphakeme, ngokuvamile ezingaba ngu-3000 kuya ku-4500 psi, okuvumela izikhathi ezinde zokusebenza kuyilapho kusalokhu kungasindi.

I-Carbon Fiber Composite Cylinders ku-EEBD kanye ne-SCBA Systems

Womabili ama-EEBD kanye nama-SCBA azuza kakhulu ekusetshenzisweni kweisilinda esiyinhlanganisela ye-carbon fibers, ikakhulukazi ngenxa yesidingo sezingxenye ezingasindi neziqinile.

Iqhaza likaI-Carbon Fiber Cylinders:

1. Engasindi: I-carbon fibre cylinders alula kakhulu kunamasilinda ensimbi endabuko, okubalulekile kuzo zombili izinhlelo zokusebenza ze-EEBD ne-SCBA. Kuma-EEBD, lokhu kusho ukuthi idivayisi ihlala iphatheka kakhulu, kuyilapho kuma-SCBA, yehlisa ubunzima bomzimba kubasebenzisi ngesikhathi sokusetshenziswa isikhathi eside.
2. Amandla Aphakeme: I-Carbon fiber idume ngokuhlala isikhathi eside kanye nokumelana nezimo ezimbi kakhulu, okuyenza ifanelekele izindawo ezimazombezombe lapho kusetshenziswa khona ama-SCBA.
3. Amandla Anwetshiwe: I-carbon fibre cylinderama-SCBA angabamba umoya onomfutho ophezulu, okuvumela lawa madivayisi ukuthi agcine ukunikezwa komoya okunwetshiwe kumamishini amade. Lesi sici asibalulekile kangako kuma-EEBD, lapho ukunikezwa komoya wesikhashana kuwumgomo oyinhloko, kodwa sinika amandla idizayini encane, elula yokuphuma ngokushesha.

Ukuqhathaniswa kwe-EEBD ne-SCBA Ezimeni Ezihlukene Zokusebenzisa

Umehluko Wokuphepha Nokusebenza

Ama-EEBD abaluleke kakhulu ezimeni eziphuthumayo lapho ukubaleka kuwukuphela kwento ehamba phambili. Idizayini yabo elula ivumela abantu abanokuqeqeshwa okuncane ukuthi banikeze idivayisi futhi baye endaweni ephephile ngokushesha. Kodwa-ke, njengoba bengenakho ukuphathwa komoya okuthuthukisiwe nezici zokuqapha, azifanelekele imisebenzi eyinkimbinkimbi ngaphakathi kwezindawo eziyingozi. Ama-SCBA, ngakolunye uhlangothi, aklanyelwe labo abadinga ukuzibandakanya emisebenzini ngaphakathi kwalezi zindawo eziyingozi. Ingcindezi ephezului-carbon fibre cylinders kuma-SCBAs aqinisekisa ukuthi abasebenzisi bangenza ngokuphephile nangempumelelo ukuhlenga, ukucisha umlilo, kanye neminye imisebenzi ebalulekile ngaphandle kokudinga ukuphuma ngokushesha.

Ukukhetha Idivayisi Elungile: Isetshenziswa nini i-EEBD noma i-SCBA

Isinqumo phakathi kwe-EEBD ne-SCBA sincike emsebenzini, imvelo, kanye nesikhathi esidingekayo sokuhlinzekwa komoya.

• Ama-EEBDzilungele izindawo zokusebenza lapho ukukhishwa ngokushesha kuyadingeka ngesikhathi sezimo eziphuthumayo, njengasezindaweni ezivalekile, emikhunjini, noma ezindaweni ezinokuvuza kwegesi okungaba khona.
• Ama-SCBAzibalulekile emaqenjini abatakuli angochwepheshe, izicishamlilo, nabasebenzi bezimboni abadinga ukusebenza ezindaweni eziyingozi isikhathi eside.

Ikusasa Le-Carbon Fiber Kumklamo Wezinsiza Zokuphefumula

Njengoba ubuchwepheshe buqhubeka, ukusetshenziswa kweisilinda esiyinhlanganisela ye-carbon fibers kungenzeka inwebeke, ithuthukise zombili izinhlelo ze-EEBD ne-SCBA. Izinto ezingasindi, ezinamandla aphezulu ze-carbon fiber zisho ukuthi amadivayisi okuphefumula esikhathi esizayo angasebenza kahle nakakhulu, okungenzeka anikeze umoya omude ngamayunithi amancane, aphathekayo. Lokhu kuziphendukela kwemvelo kuzozuzisa kakhulu abezimo eziphuthumayo, abasebenzi bokuhlenga, kanye nezimboni lapho imishini yokuphepha emoyeni ephefumulayo ibalulekile.

Isiphetho

Kafushane, ngenkathi womabili ama-EEBD nama-SCBA esebenza njengamathuluzi abalulekile okusindisa ukuphila ezimeni eziyingozi, aklanywe ngokucabangela imisebenzi ehlukene, ubude besikhathi, nezidingo zabasebenzisi engqondweni. Ukuhlanganiswa kweisilinda esiyinhlanganisela ye-carbon fibers izithuthuke kakhulu zombili izisetshenziswa, okuvumela isisindo esilula nokuqina okukhulu. Ngokuphuma kwezimo eziphuthumayo, ukuphatheka kwe-EEBD ngei-carbon fibre cylinderibaluleke kakhulu, kuyilapho ama-SCBA anengcindezi ephezului-carbon fibre cylinders inikeza ukwesekwa okubalulekile kwemisebenzi yokutakula emide, eyinkimbinkimbi. Ukuqonda umehluko phakathi kwalezi zisetshenziswa kuqinisekisa ukuthi zisetshenziswa ngendlela efanele, kukhulisa ukuphepha nokusebenza kahle ezindaweni eziyingozi.
