Ukusetshenziswa kwe-sodium sulfide ezimbonini kuhilela izimo eziyinkimbinkimbi kakhulu. Emashabhu okupenda, abasebenzi basebenza ngezingubo ezingamelani namakhemikhali ngoba i-sodium sulfide ikhipha amagesi anobuthi emazingeni okushisa aphezulu. Izitshalo zokwelapha amanzi angcolile zivame ukuyisebenzisela ukuvimba izinsimbi ezisindayo, okudinga ukulawulwa okuqinile kwesilinganiso sokudla kanye nokuhlomisa amapayipi okudla ngamadivayisi okulwa nokwakheka kwekristalu. Emafektri ephepha, lapho isetshenziselwa ukuthambisa i-pulp yokhuni, indawo yokusebenza kumele igcinwe yomile, kube nama-anti-slipping mat phansi kanye nezimpawu zokuxwayisa ezinjengokuthi “Azikho Izinkomishi Zamanzi Ezivunyelwe” ezibekwe odongeni.

Ukuthunyelwa okuqondile kusuka e-Qingdao Port, e-Tianjin Port, nase-Shanghai Port, kanye nokuthunyelwa okusebenzayo kwe-sodium sulfide okumboza amachweba amakhulu emhlabeni jikelele. Chofoza lapha ukuze uthole izinsizakalo ezisezingeni eliphezulu.
