Iron oxide pigment in the general situation without any risk. However, it is also necessary to pay attention to the production and use process. 　　Iron oxide pigment as a kind of pigment or colorant for precast concrete and building materials can be directly mixed into cement. Excellent light and low temperature resistance, but also resistant to the impact of the atmosphere, resistant to turbid gas, resistance to all alkali and other advantages. In concentrated acids, however, there is usually no risk because they are dissolved only when heated.

　　Omin pigment small make up and we talk about iron oxide pigments on the human body has no harm?
　　Long-term inhalation of iron oxide dust can stimulate the problem of pneumoconiosis, known as "iron end cooling syndrome", also known as "iron pneumoconiosis", so pay 　attention to: iron oxide resistance to the current, but in the case of water absorption and electrical conductivity. Therefore, iron oxide may become a dangerous component in the operation of electrical appliances, which will initially lead to the situation of insufficient current, and then may lead to a short circuit, which can directly threaten people's lives, so we should also pay attention to it.
