Storage Precautions Needed :

1. It is advisable to keep Sponge Iron under cover to avoid any direct contact with moisture before usage. Moisture promotes oxidation thus reduces metalization.
2. Sponge Iron needs special care during storage and transportation for which IS: 10852 stipulations may be followed.

Special care is taken while dispatching Sponge Iron from plant by putting proper sealing over the material loaded on vehicles to protect against environmental deterioration.
