STORED PRODUCTS:
Water-polluting liquids. The (possible) explosive vapor-air mixtures (also such ones that can arise through the stored/conveyed liquids in contact with air, humidity, condensation or the materials used) must be classifiable into gas group II A to II B3 as well as in the temperature code T1 to T3 (T4 on request). Example: petrol.
