Ezimweni eziphuthumayo lapho umoya ophefumulayo usengozini, kubalulekile ukuba nokuvikela okuthembekile kokuphefumula. Izinhlobo ezimbili ezibalulekile zemishini esetshenziswa kulezi zimo I-Emergency Escape Breathing Devices (EEBDs) kanye ne-Self-Contained Breathing Apparatus (SCBA). Nakuba zombili zinikeza ukuvikeleka okubalulekile, zisebenzisa izinjongo ezihlukene futhi zenzelwe izimo ezihlukene zokusebenzisa. Lesi sihloko sihlola umehluko phakathi kwama-EEBD nama-SCBA, ngokugxila ngokukhethekile endimeni yeIsilinda esiyinhlanganisela ye-carbon fibers kule mishini.
Iyini i-EEBD?
I-Emergency Escape Breathing Device (EEBD) iyidivayisi ephathekayo edizayinelwe ukuhlinzeka ngendawo yesikhashana yomoya owuphefumulayo ezimeni eziphuthumayo. Ihloselwe ukusetshenziswa ezindaweni lapho umoya ungcolile noma amazinga komoyampilo ephansi, njengalapho kuvutha umlilo noma ukuchitheka kwamakhemikhali.
Izici ezibalulekile ze-EEBDs:
- Ukusetshenziswa Kwesikhashana:Ama-EEBD ngokuvamile anikeza isikhathi esilinganiselwe sokunikezwa komoya, kusukela kumaminithi angu-5 ukuya kwangu-15. Lesi sikhathi esifushane sihloselwe ukuvumela abantu ukuba babaleke ngokuphepha ezimeni eziyingozi baye endaweni ephephile.
- Ukusebenzisa kalula:Aklanyelwe ukuthunyelwa okusheshayo nokulula, ama-EEBD ngokuvamile alula ukusebenza, adinga ukuqeqeshwa okuncane. Ngokuvamile zigcinwa ezindaweni ezifinyeleleka kalula ukuze kuqinisekiswe ukuthi zingasetshenziswa ngokushesha esimweni esiphuthumayo.
- Ukusebenza Okukhawulelwe:Ama-EEBD awaklanyelwe ukusetshenziswa okunwetshiwe noma imisebenzi ekhandlayo. Umsebenzi wabo oyinhloko uwukunikeza umoya owanele ukuze kube lula ukuphunyuka, hhayi ukusekela ukusebenza isikhathi eside.
Iyini i-SCBA?
I-Self-Contained Breathing Apparatus (SCBA) iyidivayisi ethuthuke kakhulu esetshenziselwa imisebenzi yesikhathi eside lapho umoya ophefumulayo usengozini. Ama-SCBA avame ukusetshenziswa ngabacimi bomlilo, abasebenzi bezimboni, nabasebenzi bokuhlenga abadinga ukusebenza ezindaweni eziyingozi.
Izici ezibalulekile zama-SCBAs:
- Ukusetshenziswa Kwesikhathi Eside:Ama-SCBA ahlinzeka ngokuhlinzekwa komoya okunwetshiwe, ngokuvamile okusukela kumaminithi angu-30 kuye kwangu-60, kuye ngosayizi wesilinda kanye nezinga lokusetshenziswa komoya lomsebenzisi. Lesi sikhathi esinwetshiwe sisekela kokubili impendulo yokuqala kanye nemisebenzi eqhubekayo.
- Izici Ezithuthukile:Ama-SCBA ahlome ngezici ezengeziwe njengezilawuli zengcindezi, izinhlelo zokuxhumana, namamaski ahlanganisiwe. Lezi zici zisekela kokubili ukuphepha nokusebenza kahle kwabasebenzisi abasebenza ezimeni eziyingozi.
- Idizayini Esebenza Kakhulu:Ama-SCBA aklanyelwe ukusetshenziswa ngokuqhubekayo ezindaweni ezinokucindezeleka okukhulu, okuwenza afanelekele imisebenzi efana nokucisha umlilo, imisebenzi yokuhlenga, nomsebenzi wezimboni.
I-Carbon Fiber Composite Cylinders kuma-EEBD kanye nama-SCBA
Womabili ama-EEBD kanye nama-SCBA athembele kumasilinda ukuze agcine umoya ophefumulayo, kodwa ukwakheka nezinto zokwakha zala masilinda kungahluka kakhulu.
I-Carbon Fiber Composite Cylinders:
- Ilula futhi Ihlala isikhathi eside: Isilinda esiyinhlanganisela ye-carbon fibres zaziwa ngesilinganiso sazo esikhethekile samandla nesisindo. Alula kakhulu kunensimbi evamile noma amasilinda e-aluminium, okwenza kube lula ukuwaphatha nokuyiqondisa. Lokhu kunenzuzo ikakhulukazi kuma-SCBA asetshenziswa emisebenzini enzima kanye nama-EEBD adinga ukuthathwa ngokushesha esimweni esiphuthumayo.
- Amandla Okucindezela Okuphezulu: I-carbon fibre cylinders ingagcina ngokuphephile umoya ezingcindezini eziphezulu, ngokuvamile ezifika ku-4,500 psi. Lokhu kuvumela aumthamo womoya ophezulu kusilinda esincane, esilula, enenzuzo kukho kokubili ama-SCBA nama-EEBD. Kuma-SCBA, lokhu kusho isikhathi eside sokusebenza; kuma-EEBD, ivumela idivayisi ehlangene, efinyeleleka kalula.
- Ukuphepha Okuthuthukisiwe:Izinto ezihlanganisiwe ze-carbon fibre ziyamelana nokugqwala nokulimala, zizenza ziqine kakhulu futhi zithembeke. Lokhu kubalulekile ekugcineni ubuqotho bazo zombili izinhlelo ze-EEBD ne-SCBA, ikakhulukazi ezindaweni ezinokhahlo noma ezingalindelekile.
Ukuqhathanisa ama-EEBD nama-SCBA
Inhloso kanye nokusetshenziswa:
- Ama-EEBD:Idizayinelwe ukuphunyuka ngokushesha ezindaweni eziyingozi ezinomoya wesikhathi esifushane. Azihloselwe ukusetshenziswa emisebenzini eqhubekayo noma imisebenzi enwetshiwe.
- Ama-SCBA:Idizayinelwe ukusetshenziswa isikhathi eside, ihlinzeka ngomoya othembekile wemisebenzi enwetshiwe efana nemishini yokucisha umlilo noma yokuhlenga.
Ubude besikhathi sokuhlinzeka ngomoya:
- Ama-EEBD:Nikeza umoya wesikhathi esifushane, ngokuvamile imizuzu emi-5 ukuya kweyi-15, eyanele ukubaleka engozini esheshayo.
- Ama-SCBA:Nikeza umoya omude, ngokuvamile osukela emaminithini angu-30 kuye kwangu-60, osekela ukusebenza okunwetshiwe nokuqinisekisa ukutholakala komoya okuqhubekayo.
Idizayini nokusebenza:
- Ama-EEBD:Amadivayisi alula, aphathekayo agxile ekusizeni ukubaleka okuphephile. Zinezici ezimbalwa futhi zenzelwe ukusetshenziswa kalula ezimeni eziphuthumayo.
- Ama-SCBA:Amasistimu ayinkimbinkimbi afakwe izici ezithuthukile njengezilawuli zengcindezi nezinhlelo zokuxhumana. Zakhelwe izindawo ezidinga amandla kanye nokusetshenziswa isikhathi eside.
Amasilinda:
- Ama-EEBD:Ingasebenzisaencane, isilinda esilulas enokunikezwa komoya okulinganiselwe.Amasilinda ayinhlanganisela ye-Carbon fiber ku-EEBDs ihlinzeka ngezinketho ezingasindi neziqinile zemishini yokubalekela izimo eziphuthumayo.
- Ama-SCBA:Sebenzisaisilinda esikhulus enikeza ukuhlinzekwa komoya okunwetshiwe.Isilinda esiyinhlanganisela ye-carbon fibres ukuthuthukisa ukusebenza kwama-SCBA ngokunikeza umthamo ophezulu kanye nokunciphisa isisindo sisonke sesistimu.
Isiphetho
Ukuqonda umehluko phakathi kwama-EEBD nama-SCBA kubalulekile ekukhetheni okokusebenza okufanele ngezidingo ezithile. Ama-EEBD adizayinelwe ukuphunyuka kwesikhashana, ahlinzeka ngendawo yomoya elinganiselwe ukusiza abantu ngabanye ukuba baphume ngokushesha ezimweni eziyingozi. Ama-SCBA, ngakolunye uhlangothi, akhelwe ukusetshenziswa isikhathi eside, asekela imisebenzi eyandisiwe ezindaweni eziyinselele.
Ukusetshenziswa kweIsilinda esiyinhlanganisela ye-carbon fibers kuwo womabili ama-EEBD nama-SCBA athuthukisa ukusebenza nokuphepha kwalawa madivayisi. Amandla abo angasindi, aqinile, futhi anomfutho ophezulu awenza abe ingxenye ebalulekile kukho kokubili ukuphunyuka okuphuthumayo kanye nezimo zokusebenza ezinde. Ngokukhetha okokusebenza okufanele kanye nokuqinisekisa ukunakekelwa okufanele, abasebenzisi bangavikela ngempumelelo ukuphepha nokuphila kwabo ezimeni eziyingozi.
