Umthelela we-Sodium Sulfide Emvelweni:

I. Izingozi Zempilo
Izindlela Zokuchayeka: Ukuphefumula, ukugwinya.
Imiphumela Yempilo: Lesi sidakamizwa singabola emgodini wokugaya ukudla, sikhiphe i-hydrogen sulfide (H₂S). Ukusidla kungaholela ebuthi be-hydrogen sulfide. Kuyalimaza isikhumba namehlo.

II. Idatha Yobuthi be-Sodium Sulfide kanye Nokuziphatha Kwemvelo
Ubuthi Obubukhali: LD₅₀ (igundane, ngomlomo): 820 mg/kg; LD₅₀ (igundane, ngemithambo): 950 mg/kg.

Ukwenziwa kwamakhemikhali akukwazi ukwenzeka ngaphandle kwe-sodium sulfide, okuyizinto eziyinhloko zokukhiqiza amadayi e-sulfurized, irabha e-vulcanized kanye neminye imikhiqizo. Chofoza lapha ukuze uthole amanani ancishisiwe.
