3.Packaging and storage
250kg/drum
The warehouse is ventilated and dry at low temperature; store separately from food additives and alkalis. As fluosilicic acid is strongly corrosive, special measures need to be taken when storing it. Firstly, materials with good acid resistance should be used to store fluosilicic acid, such as polyethylene plastic containers or glass containers. The storage container should be well sealed and placed in a dry, well-ventilated area. The storage area should be kept away from sources of ignition and flammable materials. For large-scale storage of fluorosilicic acid, specially designed storage tanks or tanks with corresponding safety facilities and leakage alarm systems can be used.
4.Safety protection
