5. Handling and Storage:
Closed operation, local exhaust. Prevention of dust released into the shop air. Operators must receive special training, strict compliance with operating rules. Proposed operators to wear self-absorption filter respirators, wear chemical safety glasses, wear rubber acid suit, wear rubber gloves acid. To avoid dust. Avoid oxidizing agents, alkali exposure. Equipped with emergency spill equipment. Empty containers may be harmful residues.Store in a cool, ventilated warehouse. Away from fire and heat. To prevent direct sunlight. Packaging must be sealed and not exposed to moisture. Should be the oxidant, alkali and other stored separately and avoid mixing reservoir. Storage areas should be equipped with suitable host material spill. Easily oxidized in air, experiments must now use the existing service

6. Apllication:
Ferrous sulphate flocculation used for water purification, as well as for urban and industrial sewage to remove phosphate. In order to prevent eutrophication of water bodies, a large number of ferrous sulphate is used as reducing agent, the main reduction of chromate in cement.
