Ukuqonda Umahluko phakathi kwe-EEBD kunye ne-SCBA: Ukugxila kwi-Carbon Fiber Composite Cylinders

Kwiimeko zongxamiseko apho umoya ophefumlayo usengozini, ukuba nokhuseleko oluthembekileyo lokuphefumla kubalulekile. Iindidi ezimbini eziphambili zezixhobo ezisetyenzisiweyo kwezi ziganeko zi-Emergency Escape Breathing Devices (EEBDs) kunye ne-Self-Contained Breathing Apparatus (SCBA). Ngelixa zombini zibonelela ngokhuseleko oluyimfuneko, zisebenza ngeenjongo ezahlukeneyo kwaye ziyilelwe iimeko zokusetyenziswa ezahlukeneyo. Eli nqaku liphonononga umahluko phakathi kwe-EEBDs kunye ne-SCBAs, ngokugxila ngokukodwa kwindima yecarbon fiber composite cylinders kwezi zixhobo.

Yintoni i-EEBD?

Isixhobo sokuphefumula esiphuthumayo (EEBD) sisixhobo esiphathwayo esenzelwe ukubonelela ngexesha elifutshane lomoya ophefumulayo kwiimeko ezingxamisekileyo. Yenzelwe ukusetyenziswa kwiindawo apho umoya ungcolisekile okanye amanqanaba eoksijini aphantsi, njengaxa kutsha okanye kuchitheke iikhemikhali.

Iimpawu eziphambili zeeEEBDs:

• Ukusetyenziswa kwexesha elifutshane:I-EEBDs inika ixesha elilinganiselweyo lonikezelo lomoya, ukusuka kwi-5 ukuya kwi-15 imizuzu. Eli xesha lifutshane lenzelwe ukuvumela abantu ukuba babaleke ngokukhuselekileyo kwiimeko eziyingozi baye kwindawo ekhuselekileyo.
• Ukusebenziseka ngokulula:Idizayinelwe ukuthunyelwa ngokukhawuleza nangokulula, ii-EEBD zihlala zilula ukusebenza, zifuna uqeqesho oluncinci. Ngokuqhelekileyo zigcinwa kwiindawo ezifikelelekayo ukuqinisekisa ukuba zingasetyenziswa ngokukhawuleza kwimeko engxamisekileyo.
• Ukusebenza okulinganiselweyo:Ii-EEBD azenzelwanga ukusetyenziswa ixesha elide okanye imisebenzi enzima. Umsebenzi wabo oyintloko kukubonelela ngomoya owaneleyo ukuququzelela ukuphunyuka okukhuselekileyo, kungekhona ukuxhasa imisebenzi emide.

Yintoni iSCBA?

I-Self-Contained Breathing Apparatus (SCBA) sisixhobo esiphezulu ngakumbi esisetyenziselwa imisebenzi yexesha elide apho umoya ophefumulayo uphazamiseka. I-SCBAs isetyenziswa ngokuqhelekileyo ngabacimi bomlilo, abasebenzi bamashishini, kunye nabasebenzi bokuhlangula abafuna ukusebenza kwiindawo ezinobungozi.

Iimpawu eziphambili zeeSCBAs:

• Ukusetyenziswa kwexesha Elide:I-SCBAs zibonelela ngobonelelo lomoya olwandisiweyo, ngokuqhelekileyo ukusuka kwi-30 ukuya kwimizuzu engama-60, ngokuxhomekeke kubukhulu be-cylinder kunye nesantya sokusetyenziswa komoya somsebenzisi. Eli xesha landisiweyo lixhasa zombini impendulo yokuqala kunye nemisebenzi eqhubekayo.
• Iimpawu eziphambili:I-SCBAs zixhotyiswe ngeempawu ezongezelelweyo ezifana nabalawuli boxinzelelo, iinkqubo zonxibelelwano, kunye neemaski ezidibeneyo. Ezi mpawu zixhasa zombini ukhuseleko kunye nokusebenza kakuhle kwabasebenzisi abasebenza kwiimeko ezinobungozi.
• Uyilo oluSebenza ngokuPhezulu:Ii-SCBA zenzelwe ukusetyenziswa ngokuqhubekayo kwiindawo ezinoxinzelelo oluphezulu, zizenza zilungele imisebenzi efana nokucima umlilo, imisebenzi yokuhlangula, kunye nomsebenzi wezoshishino.

I-Carbon Fiber Composite Cylinders kwii-EEBDs kunye ne-SCBAs

Zombini ii-EEBD kunye ne-SCBA zixhomekeke kwiisilinda ukugcina umoya ophefumlayo, kodwa uyilo kunye nezixhobo zala masilinda zinokuhluka kakhulu.

I-Carbon Fiber Composite Cylinders:

• Ikhaphukhaphu kwaye ihlala ixesha elide: Ikhabhon fiber composite cylinders zaziwa ngomlinganiselo wazo okhethekileyo wamandla kubunzima. Zikhaphukhaphu kakhulu kunentsimbi yesintu okanye iisilinda ze-aluminiyam, ezenza kube lula ukuzithwala nokuzilawula. Oku kunenzuzo ngokukodwa kwii-SCBA ezisetyenziselwa imisebenzi enzima kunye nee-EEBDs ezifuna ukuqhutyelwa ngokukhawuleza kwimeko kaxakeka.
• Ubunakho boxinzelelo oluphezulu: Ikhabhoni fiber cylinders inokugcina ngokukhuselekileyo umoya kuxinzelelo oluphezulu, rhoqo ukuya kuthi ga kwi-4,500 psi. Oku kuvumela ukuba aumthamo womoya ophezulu kwi-cylinder encinci, elula, enenzuzo kuzo zombini ii-SCBA kunye nee-EEBDs. Kwii-SCBAs, oku kuthetha ixesha elide lokusebenza; ii-EEBDs, ivumela isixhobo esihlangeneyo, esifikeleleka lula.
• Ukhuseleko olomeleziweyo:Izixhobo zekhabhoni ezidityanisiweyo zefiber ziyamelana nokubola kunye nomonakalo, zizenza ziqine kwaye zithembeke. Oku kubalulekile ekugcineni imfezeko yazo zombini iinkqubo ze-EEBD kunye ne-SCBA, ngakumbi kwiimeko ezirhabaxa okanye ezingalindelekanga.

Ukuthelekisa ii-EEBDs kunye ne-SCBAs

Injongo kunye nokusetyenziswa:

• Ii-EEBDs:Yenzelwe ukubaleka ngokukhawuleza kwiindawo ezinobungozi kunye nonikezelo lomoya lwexesha elifutshane. Azenzelwanga ukusetyenziswa kwimisebenzi eqhubekayo okanye imisebenzi eyandisiweyo.
• I-SCBAs:Yenzelwe ukusetyenziswa kwexesha elide, ukubonelela ngomoya othembekileyo kwimisebenzi eyandisiweyo efana nokucima umlilo okanye ukuhlangula.

Ubude bexesha lokubonelelwa ngoMoya:

• Ii-EEBDs:Ukubonelela ngomoya wexesha elifutshane, ngokuqhelekileyo imizuzu emi-5 ukuya kwi-15, eyanele ukubaleka kwingozi ekhawulezileyo.
