1. Chovala chokhala ndi moyo chodzaza ndi zinthu za buoyancy, ndiko kuti, nsaluyo imapangidwa ndi nsalu ya nayiloni kapena neoprene, ndipo zinthu za buoyancy zimadzazidwa pakati.
2. Jekete lamoyo la inflatable: Linapangidwa ndi zinthu zolimba kwambiri zomwe sizingalowe m'madzi, zofanana ndi mfundo ya inflatable lifebuoy kapena mphete yosambira. Agawika mu inflatable wodziwikiratu kapena kungokhala inflatable. Koma chofunika kwambiri pa mtundu uwu wa jekete ya moyo ndi: kupewa mwamtheradi zinthu zakuthwa kuboola kapena kuvala wosanjikiza madzi, zomwe zingabweretse zotsatira zosayembekezereka pambuyo kutayikira mpweya.

khosi likulendewera

Musanafufuze, valani ngati vest. Mukagwera m'madzi kapena mukuvutika m'madzi, tsegulani valavu yamanja, ikani mofulumira mumasekondi a 5, ndipo thupi la munthu limayandama pamwamba kuti mupulumutse moyo. Pali cholumikizira pakamwa pa jekete yopulumutsa moyo, yomwe imathanso kuwomba mpweya. Pamene mukuvutika, valavu yamanja imatsegulidwa, mpweya wothamanga kwambiri wa silinda umadzazidwa mu jekete lamoyo, ndipo chifuwa chakutsogolo ndi kumbuyo kwa vest zimakwera mofulumira kuti apange thumba la mpweya, lomwe lingapangitse 10 kg ya buoyancy. m'madzi kuti ayandame thupi la munthu pamwamba.

chiuno chikulendewera
Panthawi yopuma, ulusi umakhazikika m'chiuno, ndipo ukagwera m'madzi mwangozi, umakwezedwa kuti upange lifebuoy yofanana ndi kavalo, yomwe imazungulira m'chiuno mwa munthu womirayo, kotero kuti womirayo amayandama pamadzi. Zovala zokonzeka zimakwaniritsa zofunikira za Msonkhano wa SOLAS ndi ndondomeko zaposachedwa za IMO, ndipo zatsimikiziridwa ndi CCS, ndipo zimaloledwa kugwiritsidwa ntchito m'madera a malire a zombo, zombo, zotsutsana ndi kuzembetsa panyanja, kumanga madzi, masewera a madzi. , salvage, oyendetsa ndege, kulamulira madzi osefukira, nsomba za m'nyanja ndi madera ena.

fanny paketi
The airbag pamaso inflation anaika mu thumba laling'ono ndi kugwirizana ndi lamba m'chiuno ndi womangidwa m'chiuno. Sizilepheretsa kugwira ntchito kwabwino kwa ogwira ntchito pamadzi komanso pabwalo. Pambuyo pa kukwera kwa mitengo, airbag imangotuluka m'thumba. Chifukwa cha kugwirizana kwa chitsulocho, airbag imayendetsa thupi la munthu kuti liyandama pamadzi. Panthawiyi, airbag ikhoza kuikidwa pamutu ndikuyika pakhosi ndi pachifuwa ndi manja onse. Mphamvu ya buoyancy ndi yofanana ndi jekete lamoyo la inflatable. .
