Umthelela we-Sodium Sulfide emvelweni:

I. Iingozi zezamaphilo
Iindlela zokuvezwa: Ukuphefumula, ukungena.
Imiphumela yezamaphilo: Into le ingabola emgudwini wesisu, ikhuphe i-hydrogen sulfide (H₂S). Ukungena kungadosela ekutheni kube nobuthi be-hydrogen sulfide. Iyabola isikhumba namehlo.

II. Idatha ye-Sodium Sulfide ye-Toxicological kanye nokuziphatha kwebhoduluko
Ubuthi obubukhali: LD₅₀ (igundane, ngomlomo): 820 mg/kg; LD₅₀ (igundane, ngemithanjeni): 950 mg/kg.

Ukubunjwa kwamakhemikhali angeze kwakghonakala ngaphandle kwe-sodium sulfide, okuyinto eqakathekileko yokukhiqiza amadayi ane-sulfure, irabha ene-vulcanized neminye imikhiqizo. Tlika lapha ukuthola amanani wehlisiweko.
