How should Caustic Soda be stored and transported?
Sodium hydroxide (NaOH), commonly known as caustic soda, is a strong alkali with strong corrosivity. It is generally in the form of flakes or pearls, and is easily soluble in water (exothermic when dissolved in water) and forms an alkaline solution.
Caustic Soda generally adopts 25kg three-layer plastic woven bags, the inner and outer layers are plastic woven bags, and the middle layer is plastic inner membrane bags.
Caustic Soda is classified as category 8.2 alkaline corrosive goods in the classification and marking of commonly used hazardous chemicals (GB 13690-92), which belongs to class 8 dangerous goods, and the hazard code is 1823. It should be stored in a ventilated and dry warehouse or shed. The packaging container should be complete and sealed. It shall not be stored and transported together with inflammables and acids. Pay attention to damp proof and rain proof during transportation.
In case of fire, water, sand and various fire extinguishers can be used to put out the fire, but firefighters should pay attention to the corrosivity of caustic soda dissolved in water.
Caustic Soda is widely used. It is used in light textile industry such as papermaking, synthetic washing and soap, viscose fiber, rayon and cotton fabrics, pesticide, dye, rubber and chemical industry, oil drilling, petroleum industry for refining petroleum grease and tar, as well as national defense industry, machinery industry, wood processing, metallurgy industry, pharmaceutical industry and urban construction. It is also used in the manufacture of chemicals, paper, soap and detergent, rayon and cellophane, the processing of alumina from bauxite, and the mercerization of textiles, water treatment, etc.
