Indlela yokukhetha i-helmet efanelekileyo ye-bulletproof?

Isigcina-ntloko esingangenwa ziimbumbulu asisithinteli iimbumbulu, sinokuthintela ukuqhekeka kuphela, iimbumbulu zompu zinokungena lula kwiintlobo ezahlukeneyo zemigcina-ntloko yomkhosi ngaphakathi koluhlu olusebenzayo, kwaye ingamehlo amabini.Ke ngoko, kubalulekile ukukhetha isigcina-ntloko esinamandla okukhusela.

1. Uhlobo lwesigcina-ntloko

Okokuqala, kufuneka siqonde ukuba yintoni isigcina-ntloko esifuna uhlobo lwesigcina-ntloko, uhlobo lwesigcina-ntloko lubhekiselele kwindlela yolwakhiwo lwesigcina-ntloko, kunye nezakhiwo ezahlukeneyo ukuze kutshatiswe ngcono izixhobo zokulwa ezincedisayo, okanye ukuhlangabezana neemfuno ezikhethekileyo zomntu osinxibileyo ekhosini. yokulwa.Okwangoku kukho iintlobo ezintathu eziphambili ze-helmet kwimarike: i-PASGT, i-MICH kunye ne-FAST.

2. Isakhono sokukhusela

Ngokwesiko, izigcina-ntloko zazifuna kuphela ukukhuselwa kumatye abhabhayo kunye neengceba zetsimbi kwindawo yokulwa.Ke ngoko, siqhele ukusebenzisa ixabiso le-V50 ukugweba umgangatho wesakhono sokhuselo sesigcina-ntloko.Ixabiso le-V50 lithetha ukuba i-hypotenuse cylindrical projectile enobunzima be-1.1 grams isetyenziselwa ukudubula isigcina-ntloko ngesantya esahlukileyo ngaphakathi komgama ochaziweyo ukufikelela kwi-50% yokuqhekeka okunokwenzeka, kwaye isantya esiphakathi sembumbulu egxothiweyo lixabiso le-V50 Isigcina-ntloko.Okukhona iphezulu iV50, kokukhona ingcono ibulletproof yesigcina-ntloko.

3. Izinto eziphathekayo

Iimeko zokusingqongileyo ezifunekayo kwii-helmets zezinto ezahlukeneyo zikwahluke kwinkqubo yokusetyenziswa kunye nokugcinwa.Oku kukwaqwalasela okubalulekileyo xa sikhetha kwaye sithenga izigcina-ntloko.Okwangoku, izinto ezisetyenziselwa ukwenza izigcina-ntloko ze-bulletproof ziyi-PE, i-Kevlar kunye nentsimbi ye-bulletproof.

4. Umzila wesikhokelo sobuchule

Ngoku ukuze ulungelelanise neemfuno zokusetyenziswa okwahlukeneyo, i-MICH, i-FAST helmets inokuxhotyiswa ngeereyili ezinobuchule.Emva kokufaka isikhokelo sobuchule, abasebenzisi banokunxiba umbono wasebusuku, isibane esikhanyayo, ikhamera kunye nezinye izixhobo ngokulula ngakumbi ngokweemfuno zabo, nto leyo enyusa kakhulu inqanaba lolwazi, ukukwazi ukulwa kwiindawo ezahlukeneyo kunye nenqanaba elipholileyo phakathi kwamaqabane amancinci. .
