Kwiindawo zelebhu, kufuneka ulumke ngakumbi xa usebenzisa i-sodium sulfide. Ngaphambi kokusetyenziswa, kufuneka unxibe iiglasi zokhuseleko kunye neeglavu zerabha, kwaye imisebenzi yenziwa ngcono ngaphakathi kwesiciko somlilo. Nje ukuba ibhotile ye-reagent ivuliwe, kufuneka ivalwe ngoko nangoko kwingxowa yeplastiki ukuthintela ukufunxwa komswakama emoyeni, okuya kuyiguqula ibe yintlama. Ukuba ibhotile iwile ngengozi, musa ukuyihlamba ngamanzi! Okokuqala, gquma indawo echithekileyo ngesanti okanye umhlaba owomileyo, uze uyiqokelele usebenzisa ifosholo yeplastiki uyibeke kwisitya senkunkuma esikhethekileyo.

Ukusebenzisana nathi akunaxhala ngokukodwa, kubonelela ngeesatifikethi zohlalutyo lwe-COA zasimahla kunye namaphepha edatha yokhuseleko lwe-MSDS, kunye nokuxhasa uvavanyo olugunyazisiweyo lomntu wesithathu. Abahlobo abaneemfuno bamkelekile ukuba banxibelelane nathi nangaliphi na ixesha ngokucofa apha!
