Inempilo yesevisi evamile yeminyaka engu-5-7 futhi iyidivayisi esindisa ukuphila emikhunjini nasezindizeni. Ama-vests ngokuvamile enziwe ngepulasitiki ye-foam noma ukhokho. Ine-buoyancy eyanele ukugqokwa emzimbeni ukuze ikhanda lomuntu ogwilizayo likwazi ukuphuma emanzini.

1. Ijakhethi yempilo yasolwandle: Leli futhi lisetshenziswa kakhulu. Isebenzisa i-EVA foam material ngaphakathi, ecindezelwe futhi i-3D ibunjwe nge-dimensionally, futhi ukushuba kwayo kungama-4 cm (ukukhiqizwa kwasekhaya yizicucu ezingu-5-6 zezinwele ezincane, ubukhulu buba ngu-4 cm) 5-7 cm) , amajakhethi okuziphilisa akhiqizwa ngokuhambisana nemibandela evamile anezindinganiso zawo zokuvuthuza, ngokuvamile okungamahora angu-7.5 kg/24 kubantu abadala, okusho ukuthi ukuphaphama kwabantu abadala kusengafinyelela ku-7.5 kg. ngemva kokucwiliswa olwandle amahora angu-24.

2. I-self-inflating life jacket: Lolu hlobo lwejakhethi yokuphila luvame ukusetshenziselwa ukudoba izikebhe. Ingaphakathi lakhiwe ngezingqimba ezimbili zezinto zamakhemikhali ezinamandla aphezulu. Uma uwela emanzini, cindezela inkinobho yesokudla, futhi uhlangothi lwesobunxele luzohogela umoya ngokuzenzakalelayo, kuyilapho isibonisi sizosigcina size sigcwale. Ubuningi bebhantshi lokuziphilisa buoyancy ngu-10 kg/24 amahora, kodwa kufanele igcinwe kude namadwala ukuze kugwenywe umonakalo.

3. Ijakhethi enqamula izingalo yokudoba i-rock: Izimpahla zokudoba amadwala, unezinkinobho ezimbili ngaphambili okufanele azidonse aziqinise lapho ezifaka. Ukwengeza, kunemizimba emibili ekhanyayo esifubeni noma emahlombe ejakhethi yempilo, esetshenziselwa ikakhulukazi ukutakula olwandle. Lapho ukhetha, naka ukuthi kukhona yini ama-slits, bese ucabangela umbala nendwangu.

Kufanele ixutshwe ngaphakathi nangaphandle ngebhulashi ngemva kokusetshenziswa ngakunye, bese ihlanjululwa ngamanzi ahlanzekile futhi yomiswe endaweni engenawo umoya ukuze kuqinisekiswe ukuphila kwayo isikhathi eside. Ivest eyaziwayo yokudoba izinhlanzi ayenzi nje kuphela umsebenzi we-life vest evamile, kodwa futhi inemicu yokuxwayisa ecwebezelayo nekhipha ukukhanya kanye nesikhwama esifanayo nevest yokudoba, okuvumela umdobi ukuba akhulise ukuphepha kuyilapho enokwanele. isikhala sokugcina izesekeli zokudoba, ngokuphumelelayo ukubulala izinyoni ezimbili ngetshe elilodwa.
