Mu mavuriro, hakenewe kwitonda cyane mu gihe ukoresha sodium sulfide. Mbere yo gukoresha, ugomba kwambara amadarubindi y'isuku n'uturindantoki twa rubber, kandi ibikorwa ni byiza gukorwa mu gipfundikizo cy'umuriro. Iyo icupa rifunguye, rigomba guhita rifungwa mu ishashi ya pulasitiki kugira ngo ridakurura ubushuhe buva mu kirere, bugahinduka umusenyi. Niba icupa riguye ku bw'impanuka, ntukaryoge n'amazi! Banza upfuke umucanga wumye cyangwa ubutaka, hanyuma ubikusanye ukoresheje isuka ya pulasitiki ubishyire mu gikoresho cy'imyanda cyabugenewe.

Gukorana natwe nta mpungenge bitanga, bitanga impapuro z’isesengura rya COA ku buntu n’amakuru y’umutekano ya MSDS, ndetse no gushyigikira ibizamini byemewe n’abandi. Inshuti zifite ibyo zikeneye zirahawe ikaze kuduhamagara igihe icyo ari cyo cyose ukoresheje kanda hano!
