Kunywa maanzi ajisi sulfide nyiingi kwachiindi chilamfu kulakonzya kupa kuti muntu atamvwisyi kabotu, akubula luyandisisyo lwakulya, aleke mubili, masusu aatakomeni kabotu, mpawo muzyiimo zipati, kukatala akufwa.

Sodium sulfide Ntenda Zitondeezyo: Eechi chintu chilakonzya kupwasuka aawo nochajatikizyigwa naakuti chakapya chakufwambaana. Ilabola kakuli asidi, mpawo igwisya muya uukola loko.
Sodium sulfide Kupya (Kubola) Zipangwa: Hydrogen sulfide (H₂S), sulfur oxides (SOₓ).

Sodium sulfide ilagwisya ingi kabotu mumakwebo aamapepa, amyaka iili 20 yaluzibo lwakusambala kunze aacisi. Dina kuti ujane lugwasyo lwachiinga chabasyaazibwene.
