Ijacket yobomi, eyaziwa ngokuba yi-life vest, luhlobo lwempahla esindisa ubomi eyenzelwe njenge-vest kwaye yenziwe ngelaphu le-nylon okanye i-neoprene (NEOPRENE), i-buoyancy okanye i-inflatable material, izinto ezibonakalayo, kunye nezinye izinto. Inobomi benkonzo jikelele ye-5-7 iminyaka kwaye sisixhobo sokugcina ubomi kwiinqanawa kunye neenqwelomoya. Iivesti zihlala zenziwe ngeplastiki yogwebu okanye isikhokho. Ine-buoyancy eyaneleyo ukuba inxitywe emzimbeni ukuze intloko yomntu otshonayo ikwazi ukuphuma emanzini.

1. Ibhatyi yokuphila yaselwandle: Le ikwayeyona isetyenziswa kakhulu. Isebenzisa izinto ze-EVA foam ngaphakathi, ezixinzelelwe kunye ne-3D ezibunjiweyo ezintathu, kwaye ubukhulu bayo bu malunga ne-4 cm (imveliso yasekhaya ngamaqhekeza angama-5-6 eenwele ezincinci, ubukhulu bumalunga ne-4 cm) 5-7 cm) , Iibhatyi zobomi eziveliswe ngokuhambelana nemigangatho esemgangathweni zinemigangatho yazo ye-buoyancy, ngokuqhelekileyo i-7.5 kg / iiyure ezingama-24 kubantu abadala, oku kuthetha ukuba i-buoyancy yabantu abadala inokufikelela kwi-7.5 kg. emva kokuntywiliselwa elwandle iiyure ezingama-24.

2. Ibhatyi yokuphila eyazitshisayo: Olu hlobo lwebhatyi yokuphila luqhele ukusetyenziselwa ukuloba isikhephe. Ingaphakathi lakhiwe ngamacandelo amabini ezinto eziphezulu zekhemikhali. Ukuba uwela emanzini, cinezela iqhosha lasekunene, kwaye icala lasekhohlo liya kuphefumlela umoya ngokuzenzekelayo, ngelixa i-reflector iya kuyigcina ide igcwale. Ubuninzi bebhatyi yokuphila yi-10 kg/24 iiyure, kodwa kufuneka igcinwe kude nolwalwa kangangoko ukuthintela umonakalo.

3. Ibhatyi enqamlezileyo yokuloba etyeni: Izixhobo zokuloba ematyeni, unamaqhosha amabini ngaphambili ekufuneka atsalwe ngokuqinileyo xa enxiba. Ukongeza, kukho imizimba emibini e-elliptical ekhanyayo esifubeni okanye emagxeni ebhatyi yobomi, esetyenziselwa ikakhulu ukuhlangula elwandle. Xa ukhetha, qaphela ukuba kukho ii-slits, uze uqwalasele umbala kunye nelaphu.

Kufuneka ihlanjululwe ngaphakathi nangaphandle ngebrashi emva kokusetyenziswa ngalunye, emva koko ihlanjululwe ngamanzi acocekileyo kwaye yomiswe kwindawo yokungena umoya ukuze kuqinisekiswe ixesha elide. Ivest eyaziwayo yokuloba ayiyenzi nje umsebenzi wevest yobomi esemgangathweni, kodwa ikwanazo nemicu yesilumkiso ekhanyayo nekhanyayo kunye nesixhobo sepokotho esifanayo njengevest yokuloba, nto leyo evumela umlobi ukuba andise ukhuseleko lo gama ekwanele ngokwaneleyo. indawo yokugcina izixhobo zokuloba, ngokufanelekileyo ukubulala iintaka ezimbini ngelitye elinye.
