ukuhlolwa kwejakhethi yokuphila

Ijakhethi yokuphila wuhlobo lwempahla yokuzivikela yomuntu siqu (i-PPE) egcina umuntu entanta lapho ewela emanzini. Ngokuphathelene nezici zobuchwepheshe zamajakhethi okuphila, kunezindinganiso zamazwe ngamazwe kanye nemithetho kazwelonke. Amajakhethi okuphila avame ukubonakala amajakhethi empilo ayigwebu kanye namabhantshi empilo aphephethekayo. Yiziphi izindinganiso zokuhlola ama-life jackets? Ungalihlola kanjani ibhantshi lempilo eliphefumulayo?

01 indinganiso yokuhlola ibhantshi lokuphila

1. Izinga lokuhlola amajakhethi okuphila aphephethekayo

Thumela emazweni e-EU- Amajakhethi okuphila kufanele ahambisane ne-CE (noma i-ISO). Kunamazinga ama-3 esitifiketi, anqunywa ubuncane be-buoyancy obunikezwa i-lifejacket, evezwe ku-Newtons: 100N - yokuhamba emanzini avikelekile noma ukuhamba ngomkhumbi ogwini 150N - ukuhamba ngomkhumbi ogwini lolwandle 275N - ukuhamba ngomkhumbi olwandle kanye nokuphuma ngomkhumbi ngaphansi kwezimo ezimbi kakhulu e-United States. - Leli zinga likhishwe yi-United States Coast Guard (USCG). Amaleveli angu-2 esitifiketi ahlukaniswa ngokuyinhloko ngokusekelwe ku-buoyancy encane, efana namazinga aseYurophu. Ileveli I: 150N yamajakhethi empilo aphephethekayo (100N wamajakhethi empilo egwebu). Ifanele zonke izinhlobo zokuhamba ngomkhumbi, kuhlanganise nezimo ezinzima kakhulu. Izinga II: 100N wamajakhethi empilo aphephethekayo (70N wamabhantshi empilo egwebu). Ifanele ukuhamba ngomkhumbi emanzini amaphakathi nezwe.

2.Izindinganiso zikazwelonke zokuhlola amabhantshi okuphila

I-GB/T 4303-2008 Ijakhethi yempilo yasolwandle GB/T 5869-2010 Life jacket isibani GB/T 32227-2015 Marine life jacket GB/T 32232-2015 Ijazi lempilo lezingane GB/T 36508-2018 Ibhantshi lempilo le-Aviation inflatable3 GB-2012 Marine Inflatable life jacket

Kuzo zonke izimo, ama-life jackets kufanele ahlangabezane nezindinganiso zamanje zezwe okuthunyelwa kulo kanye nomsebenzi owenza kuwo.

NgoJulayi 13, 2022, kwakhululwa indinganiso eyimpoqo engu-GB 41731-2022 “Marine Inflatable Life Jackets” futhi izosetshenziswa ngokusemthethweni ngoFebhuwari 1, 2023.

02 Izidingo zokuhlola okubonakalayo zamajakhethi empilo aphefumulayo asolwandle 

1. Umbala wamajakhethi okuphila asolwandle aphefumulayo (okuzobizwa kamuva ngokuthi “amajakhethi okuphila”) kufanele ube nemibala ewolintshi-bomvu, osawolintshi-ophuzi noma imibala esobala.

2. Ijakhethi yokuphila kufanele ikwazi ukugqokwa nhlangothi zombili ngaphandle kokuhlukaniswa. Uma ingagqokwa ohlangothini olulodwa kuphela, kufanele ikhonjiswe ngokucacile ku-life jacket.

5. Uma isihloko sisesilinganisweni esimile emanzini, indawo ephelele yetheyiphu yokubuka ingemuva enamathiselwe endaweni engaphandle yebhantshi lokuphila ngaphezu kwamanzi akumele ibe ngaphansi kuka-400cm, futhi itheyiphu ebuyisela emuva izohlangabezana nezidingo. ye-IMO Resolution MSC481(102).

6. Uma ibhantshi lempilo yabantu abadala lingakhelwanga abantu abanesisindo esingaphezu kuka-140kg kanye nesiyingi sesifuba esingaphezu kuka-1750mm, kufanele kuhlinzekwe izesekeli ezifanele ukuze ibhantshi lokukhulula lixhunywe kulabo bantu.

7. Ijakhethi yokuphila izoklanywa ngolayini ophonsekayo ophonsekayo noma esinye isisetshenziswa ukuze iboshelwe ejakhethini eligqokwa omunye umuntu emanzini omile;

8. Ijakhethi yokuphila izoklanywa ngedivayisi yokuphakamisa noma okunamathiselwe ukuze idonse umuntu oligqokile emanzini imyise esikebheni sokuhlenga/isihlenga noma esikebheni sokuhlenga.

9. Ijakhethi yempilo kufanele yakhelwe ngesibani sejakhethi ephilayo, okufanele ikwazi ukuhlangabezana nezidingo.

10. I-life jacket kufanele incike ekamelweni lomoya eliphefumulayo njenge-buoyancy, futhi akufanele kube namakamelo omoya azimele angabi ngaphansi kwamabili, futhi ukwehla kwamandla emali kwanoma yiliphi elinye lamakamelo omoya akufanele kuphazamise isimo samanye amakamelo omoya. Ngemuva kokucwiliswa emanzini, kufanele kube nenqwaba yamakamelo omoya amabili omile azimele afakwe ngokuzenzakalelayo, futhi idivayisi yokwehla kwamandla emali kufanele inikezwe ngesikhathi esifanayo, futhi igumbi ngalinye lomoya lingagcwaliswa ngomlomo.

11. Ijakhethi yokuzivikela kufanele ikwazi ukuhlangabezana nezidingo ezihambisanayo lapho igumbi lomoya lilahlekelwa ukunyakaza.

03 Izidingo zokuhlolwa kwamajakhethi okuphila asolwandle aphephethekayo

8.Ukusebenza kwamanzi- Ukubuyisela: Ngemva kokuthi isihloko sigqoke ibhantshi, isikhathi sokubuyisela esimaphakathi akufanele sibe sikhulu kunesilinganiso sesikhathi sokubuyisela kanye ne-1 uma ugqoke ijakhethi yempilo yereferensi yabantu abadala (RTD). Uma kunesimo “esingaphenduki”, inani elithi “non-flip” akumele lidlule inani lezikhathi lapho i-RTD igqokwa khona. I-RTD izohlangabezana nezimfuneko ku-IMO MSC.1/Circ1470 – Ibhalansi emile: Uma isihloko sikwibhalansi emile futhi ibhantshi elikhethiwe libheke phezulu, izohlangabezana nezimfuneko ezilandelayo. a) Ubude obucacile: Isilinganiso sobude obucacile bazo zonke izifundo akumele sibe ngaphansi kobude obujwayelekile obucacile uma ugqoke i-RTD susa u-10mmo b) I-engeli ye-Torso: I-engeli ye-Torso: I-engeli ye-trunk emaphakathi yazo zonke izifundo akufanele ibe ngaphansi kwe-engeli ye-trunk evamile lapho ugqoke i-RTD. khipha 10mmo Iya ku-10°-diving bese uwela emanzini: Ngemva kokuwela emanzini futhi utshuze usesimweni esilindile ugqoke ibhantshi elisindisa ukuphila, izisebenzi zokuhlola zizohlangabezana nezimfuneko ezilandelayo: a) Gcina abasebenzi abahlolayo bebheke phezulu, futhi ubude obucacile babo bonke abasebenzi bokuhlola ukusuka emanzini abukho ngaphansi kuka-5103 Isilinganiso sobude obucacile lapho ugqoke i-RTD njengoba kunqunywa ukuhlola khipha u-15mm: b) Ijakhethi lokuhlangula alisuki futhi alibangeli ukulimala kubasebenzi abahlolayo: c) akuphazamisi ukusebenza kwamanzi noma ukuphuka kweseli elishintshashintshayo: d) akubangeli ukuba kwehla noma konakaliswe ukukhanya kwejakhethi yempilo. – Ukuzinza: Ngemva kokuba isihloko sisemanzini, ibhantshi lokukhulula akufanele linyakaze libheke kolunye ukuze ubuso bomuntu oxoxwayo buphume emanzini. Okungenani inani elifanayo lezifundo ezisesimeni esifanayo nalapho ugqoke i-RTD. – Ukubhukuda nokuphuma emanzini: Ngemva kokubhukuda ama-25m, inani lezifundo ezigqoke amajakhethi okuzivikela ezingagibela isihlenga sokuphila noma ipulatifomu eqinile engu-300mm ngaphezu kwamanzi akufanele libe ngaphansi kuka-2/3 yenani lezifundo. ngaphandle kwamajakhethi okuzivikela .

9.Umthwalo wekhanda ophefumulayoNgemuva kokuthi ikhanda eliphefumulayo lingaphansi kwamandla (220±10)N kusuka kuzo zonke izinhlangothi, akufanele kube khona umonakalo. Ijakhethi yokuphila akufanele ivuze umoya futhi ihlale ingenawo umoya imizuzu engu-30.

10.Ngaphansi kwengcindeziIjakhethi yokuphila ngaphansi kwesimo esijwayelekile akufanele ibe nokuvuvukala noma ukuguqulwa kwezakhi zemishini ngemva kokuthwala umthwalo we-75kg, futhi akufanele kube khona ukuvuza komoya.

11. Ukusebenza kwengcindezi- I-Overpressure: I-lifejacket kufanele ikwazi ukumelana nengcindezi yangaphakathi eyeqile ekamelweni lokushisa. Kufanele ihlale iqinile futhi igcine le ngcindezi ye-30min.-I-valve yokukhululwa: Uma i-lifejacket ifakwe i-valve yokukhulula, kufanele ikwazi ukuqinisekisa ukuthi ukucindezela ngokweqile kukhishwa. Ijakhethi yempilo izohlala injalo futhi igcine ukucindezela kwayo imizuzu engu-30, ngeke ibonise izimpawu zokulimala njengokugqabuka, ukuvuvukala noma ukuguquka kwezakhi zemishini, futhi ngeke ilimaze ngokusobala izingxenye eziphefumulayo. - Ukugcinwa komoya: I-life jacket inflatable air room igcwele umoya, futhi ibekwe ekamelweni lokushisa amahora angu-12, ukwehla kwengcindezi akufanele kube ngaphezu kuka-10%.

12.Izingxenye zensimbi- Izingxenye zensimbi nezinto ezisemajakhethini okuphila kufanele zimelane nokugqwala kwamanzi olwandle. Ngemva kokuhlolwa kwesifutho sikasawoti ngokuhambisana no-5.151, izingxenye zensimbi ngeke zibonise ukugqwala okusobala noma umthelela kwezinye izingxenye zejakhethi yempilo futhi ngeke zehlise ukusebenza kwejakhethi yempilo. – Uma izingxenye zensimbi zejazi lokuphila zibekwe ebangeni elingama-500mm ukusuka kwikhampasi kazibuthe, ithonya lezingxenye zensimbi kwikhampasi kazibuthe akufanele lidlule u-5°.

13. Vimbela ukwehla kwamandla emaliIjakhethi yokuphila kufanele ibe nomsebenzi wokuvimbela ukwehla kwamandla emali ngengozi. Okungenhla yizindinganiso zokuhlola amabhantshi okuphila athunyelwa e-European Union, e-United States, izindinganiso zikazwelonke ezifanele zamabhantshi okuphila, kanye nempahla, ukubukeka kanye nezidingo zokuhlola endaweni yamajakhethi kazwelonke asolwandle aphephethekayo.
