Hariho ubwoko butandukanye bwibigo cyangwa ababikora mu ruganda rukora urugi:
Icya mbere nukwigana ibishushanyo byandi masosiyete cyangwa ababikora.Ibicuruzwa nkibi bigo cyangwa ababikora ntibifite ibishushanyo mbonera nubushobozi bwo guteza imbere ibicuruzwa bishya.
Iya kabiri ni ibigo cyangwa ababikora batanga cyane cyane inzugi za aluminiyumu, inzugi zicyuma cyangwa ibyuma byumuryango.Ubu bwoko bwibicuruzwa bifatwa nkibintu byinshi, byita ku biciro, kandi ntibisaba iterambere ryibicuruzwa no guhanga udushya.
IISDOO, uruganda rukora inzugi zinc alloy yumuryango hamwe nibisubizo byibyuma byumuryango, ntabwo bifite ubushobozi bwo guteza imbere ibicuruzwa kubwoko butandukanye bwabakiriya hamwe nibisabwa kumuryango, ariko kandi hamwe nubushobozi bwo kwamamaza no kuzamura mumasoko atandukanye.
Iya gatatu ni ikirango cyambere mubutaliyani.Ibicuruzwa byabo bikozwe cyane cyane mu muringa.Ikirango cyabo gifite izina ryiza cyane kwisi yose.Nyamara, ibicuruzwa byabo birashobora kuboneka kubakiriya bake --- abakiriya beza cyane.
