1. Indawo yokutshiza yesalfure kulula ukuyisebenzisa, kwaye ingqokelela ye-asidi yesulfure izinzile, ethi inciphise ivumba le-so2 kwaye inciphise ungcoliseko lwendalo.
2. Inqaba yesitshiza yohlobo lokutshiza kulula ukuyilungisa nokuyigcina. Ukuba isiphumo sihle, akukho sondlo phantse unyaka. Akukho fayibha yeglasi eyomeleziweyo fan yeplastiki okanye fan yeceramic.
3. Inqaba yesalfera yohlobo lokutshiza inokubakho kakuhle kwe-SO2. Izinga lokufakwa kwe-SO2 ngokubanzi lingaphezulu kwama-95%. Izinga lokufunxa kwezinye iitawuli zesalfure lihlala lijikeleze ama-75%, eligcina iindleko ezininzi zesulfure ngonyaka omnye.
