Etindzaweni telabhorethri, kucaphela lokungetiwe kuyadzingeka uma uphatsa i-sodium sulfide. Ngaphambi kusetjentiswa, emagogolosi ekuphepha kanye nemagilavu ​​erabha kumele kugcotjwe, futsi imisebenti yentiwa kahle ngaphakatsi kwe fume hood. Uma lelibhodlela le reagent selivulekile, kumele livalwe ngekushesha esikhwameni sepulasitiki kwentela kuvikela kumuncwa kwemswakama emoyeni, lokutawugucula libe yinhlanganisela. Uma lelibhodlela lishaywa ngengoti, ungaligezi ngemanti! Kwekucala, vala lokucitsekile ngesihlabathi lesomile noma umhlabatsi, bese uyakubutsa usebentisa lifosholo lepulasitiki esitjeni lesiniketwe imfucuza.

Kusebentisana natsi ikakhulukati akukhatsateki, kuniketa titifiketi tekuhlatiya te-COA mahhala kanye nemaphepha emininingwane yekuphepha ye-MSDS, kanye nekusekela kuhlolwa kwebantfu besitsatfu lokuneligunya. Bangani labanetidzingo bamukelekile kutsi basitsintse noma nini ngekuchafata lapha!
