A large number of ferrous sulfate is used as reducing agent, the main reduction of chromate in cement. Coloration Tannin inks and other inks iron production need to use ferrous sulfate. Mordant dyeing wood also contains ferrous sulfate. Law in China Blue, indigo dye to form insoluble matter printed on the fabric, then ferrous sulfate reduced to indigo white.

Ferrous sulphate with the turbine condenser yellow copper contacts inside the tube in its resistance to corrosion on the surface of the protective layer. Fire Fighting Measures Hazardous characteristics: a reductive. Heat released by the decomposition of toxic gases. Hazardous combustion products: sulfur oxides. Fire fighting methods: general fire firefighters must wear protective clothing, fire in the wind. When fighting moved to the extent possible, empty containers from the fire Department. Then select the appropriate reason under the fire extinguishing agent. Spill contingency Emergency Treatment: isolation leakage polluted area with restricted movement. Recommended emergency personnel wearing respirators, the general work clothes to wear. Do not direct contact with leakage. Small leak: Avoid dust, carefully scanning, data on dry, clean, covered containers. A large number of leaks: recycling or shipped to the collection of waste disposal sites. Disposal and storage operations Handling Precautions: 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. Storage Precautions: 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. Transportation Note To complete the time of shipment packing, loading should be conservative. Transportation process to ensure that the container does not leak, did not fall, not fall, no damage. Strictly prohibited and oxidizer, alkali, food chemicals, etc. mixed mixed transportation. Transportation should prevent exposure, rain, anti-high temperature.
