Transport & Storage
Polyethylene plastic drum with phosphoric acid, barrel with inside and outside to cover sealing tightly. should clear signs indicate: product name, specification, net weight, “corrosive materials” sign. Secondary inorganic acid corrosion of goods, dangerous compasses Numbers: 93002. Should be stored in a cool, well-ventilated area. High in the winter cold region to phosphate, prevent freezing, attention heat leakage preventing container rupture. With alkali, toxic substances, and other corrosive materials were away. When will prevent the rain and sun exposure. When will gently with violent collisions, prevent forbidden container. Fire, usable dry sand, powder fire extinguisher to save.
