  Safety issues
  Inhaled, intake harmful. To eyes, skin, and the upper respiratory tract mucous membrane are stimulating . Copper carbonate inhaled smoke can cause metal smoke hot, cause hepatic, kidney damage and hemolysis. Long time inhaled can cause lung fibre hyperplasia.
  Storagre
  Should be stored in dry ventilation warehouse. Must be sealed firm , prevent moisture and agglomerate. Not with strong acid, strong alkali goods must be of lay aside. Containing must be vertical on pallet, at the same time with reel paper firm.
  Package: 25kg/bag, woven bag with sealed plastic package inside.
  Implementation of standard: HG3-1075-77
