1. Ijazi lokuphila eligcwele izinto zokuthambisa, okungukuthi, indwangu yenziwe ngendwangu ye-nylon noma i-neoprene, futhi impahla ye-buoyancy igcwele phakathi.
2. Ijakhethi yempilo ephephethekayo: Lenziwe ngezinto eziqinile ezingangeni emanzini, ezifana nesimiso se-lifebuoy ephephethekayo noma iringi yokubhukuda.Ihlukaniswe yaba inflatable okuzenzakalelayo noma yekwentiwa inflatable.Kodwa into ebaluleke kakhulu yalolu hlobo lwejakhethi yokuphila ukuthi: gwema ngokuphelele izinto ezibukhali ezibhoboza noma ukugqoka ungqimba olungangeni manzi, okuzodala imiphumela engathi sína engacabangeki ngemva kokuvuza komoya.

ukulenga intamo

Ngaphambi kokufaka umoya, yigqoke njengevest.Uma uwela emanzini noma ucindezelekile emanzini, vula i-valve yezandla, futha ngokushesha ngemizuzwana emi-5, bese umzimba womuntu untanta phezulu ukuze usindise ukuphila.Kunomlomo phezu kwejakhethi yokuphila, ekwazi nokushaya umoya.Lapho ucindezelekile, i-valve yezandla iyavulwa, igesi yokucindezela okuphezulu yesilinda igcwaliswa ejazini lokuphila, futhi isifuba sangaphambili nangemuva kwe-vest zivuthelwa ngokushesha ukuze zenze isikhwama somoya, esingakhiqiza i-10 kg ye-buoyancy. emanzini ukuntanta umzimba womuntu phezulu.

ukhalo lulenga
Ngesikhathi sokuzilibazisa, i-webbing ilungiswa okhalweni, futhi ngemva kokuwela emanzini ngephutha, iphefumulelwe ukuze yenze i-lifebuoy emise okwehhashi, ezungeze ukhalo lomuntu ominzayo, ukuze ominzayo antante emanzini.Izingubo ezenziwe ngomumo zihlangabezana nezidingo zeSivumelwano se-SOLAS kanye nemininingwane yakamuva ye-IMO, futhi ziqinisekiswe yi-CCS, futhi zivunyelwe ukusetshenziswa emikhakheni yemingcele yemikhumbi, imikhumbi, ukulwa nokushushumbiswa kwasolwandle, ukwakhiwa kwamanzi, imidlalo yamanzi. , ukuhlenga, ukundiza, ukulawula izikhukhula, ukudoba olwandle kanye neminye imikhakha.

iphakethe lika-fanny
I-airbag ngaphambi kokwehla kwamandla emali ifakwa esikhwameni esincane futhi ixhunywe nebhande okhalo futhi iboshwe okhalweni.Ayivimbeli ukusebenza okuvamile kwabasebenza emanzini nasebhodini.Ngemuva kokwehla kwamandla emali, i-airbag ivele iphume esikhwameni.Ngenxa yokuxhumana kwebhande, i-airbag ishayela umzimba womuntu ukuba untante phezu kwamanzi.Ngalesi sikhathi, i-airbag ingafakwa phezu kwekhanda futhi ibekwe entanyeni nasesifubeni ngezandla zombili.Umphumela we-buoyancy ufana nowejakhethi yempilo ephefumulayo..
