The transport of orthophosphoric acid (phosphoric acid) includes the delivery of inorganic acids of moderate strength, which are naturally colorless crystals that absorb moisture from the air. Since this acid is easily soluble in liquids (water, ethanol, various solvents), the transportation of phosphoric acid is the delivery of an 85 percent mixture with water, where the mass of orthophosphoric acid exceeds 73 %. Such mixtures of concentrated acids have a strong viscosity and a high density of about 1.69 g / cm3. The salt of orthophosphoric acids is called phosphates. ADR classifies the transport of orthophosphoric acid as the transport of caustic substances of hazard class 8.


-During soldering as a flux;
-As a cleaner for rusty places on metals with subsequent corrosion protection;
-As a component in freons;
-As a food additive E338 and as an acidity regulator in highly carbonated liquids;
-In the form of a refractory component for processing materials;
-When creating phosphorous fertilizers for agricultural purposes;

Transportation of orthophosphoric acid is a transit of dangerous goods, because of its aggressiveness. Loading and unloading should be carried out in rooms with ventilation, and employees carrying out these activities, as well as drivers, should use protective clothing, shoes, respirators, glasses and acid-resistant gloves, since contact with phosphoric acid causes burns to the epithelium, mucosa and respiratory organs. During the transportation of phosphoric acid, containers and packaging are used in the form of glass, polyethylene bottles, canisters, barrels, or in the bulk method, steel tanks and tank containers with internal rubberized coating according to the rules for the delivery of dangerous goods. When transporting food grade orthophosphoric acid, it is packed in glass bottles with a volume of 20 dm3
