Mu malo oyeretsera, pamafunika kusamala kwambiri mukamagwiritsa ntchito sodium sulfide. Musanagwiritse ntchito, magalasi oteteza ndi magolovesi a rabara ayenera kuvala, ndipo ntchito ziyenera kuchitika bwino mkati mwa chivundikiro cha utsi. Botolo lothandizira likatsegulidwa, liyenera kutsekedwa nthawi yomweyo mu thumba la pulasitiki kuti chinyezi chisalowe mumlengalenga, zomwe zingasinthe kukhala phala. Ngati botololo lagubuduzidwa mwangozi, musatsuke ndi madzi! Choyamba, phimbani malo otayikirawo ndi mchenga wouma kapena dothi, kenako muwasonkhanitse pogwiritsa ntchito fosholo ya pulasitiki mu chidebe chotayira zinyalala.

Kugwira ntchito limodzi ndi ife sikuli ndi nkhawa, kupereka satifiketi yaulere yowunikira COA ndi mapepala a data yachitetezo cha MSDS, komanso kuthandizira mayeso ovomerezeka a chipani chachitatu. Anzanu omwe ali ndi zosowa ndi olandiridwa kuti alankhule nafe nthawi iliyonse podina apa!
