五 .Ukugcina
I-1. Ukuthatha amanyathelo okuphatha okukhuselekileyo
Kulumkele ukunxibelelana nolusu kunye namehlo. Kunqande ukuphefumla komphunga okanye inkungu.
Hlala kude nemithombo ye-pings-Akukho milinganiso yokutshaya.Takek yokuthintela ukwakhiwa kwe-elektrostatic
intlawulo.
2. Iimeko zokugcina ngokukhuselekileyo, kubandakanya naziphi na iingxaki
Gcina kwindawo epholileyo. Gcina iflethi ivaliwe ngokuqinileyo kwindawo eyomileyo nenefreyimu. Izikhongozeli ezivuliweyo kufuneka zivalwe ngononophelo kwaye zigcinwe zilungile ukuthintela ukuvuza.
Intsalela eyomileyo iyaqhuma. Gcina phantsi kwegesi ye-inert. Vavanya ukwenziwa kwe-peroxide amaxesha ngamaxesha naphambi kokukhululeka.
