Protection and storage of granular alkali
Among the solid alkalis, flake sodium hydroxide and granular sodium hydroxide are commonly used, and granular sodium hydroxide is easier to use than flake sodium hydroxide. However, the production process of granular sodium hydroxide is difficult and complicated, so the price of granular caustic soda is slightly higher.
Toxicity protection of granular sodium hydroxide
Granular sodium hydroxide is highly corrosive. The solution or dust will splash on the skin, mainly on the mucous membranes, causing soft skin scabs and penetrating deep tissues. Because of burn scars. Splashing in the eyes will not only damage the cornea, but also damage the deep tissues of the eyes. Rinse with water for 10 minutes; if it splashes on the skin, dispose of it in time; if it splashes on the eyes, rinse with water or saline for 15 minutes, and then add 2% Novocaine. Severe cases should be sent to hospital for treatment. The maximum allowable concentration of caustic dust in the air is 0.5 mg/m3. The operators of granular alkali need to wear work clothes, masks, protective glasses, rubber gloves, rubber aprons, rubber boots and other labor insurance products. Apply a neutral hydrophobic ointment on the skin. The workshop is well ventilated.
Fine crystal sodium hydroxide
Packaging, storage and transportation of granular sodium hydroxide:
Generally, a 25kg three-layer plastic woven bag is used as sodium hydroxide particles, the inner and outer layers are plastic woven bags, and the middle layer is a plastic inner bag. Flake caustic soda is divided into 8.2 alkaline corrosive agents according to GB13690-92 "Classification and Labeling of Common Hazardous Chemicals", which belongs to 8 kinds of dangerous goods, code 1823. Should be stored in a ventilated and dry warehouse or warehouse. The packaging container should be completely sealed. Do not store and mix flammable materials and acids. Pay attention to moisture and rain during transportation. In case of fire, water, sand and various fire extinguishers can be used to extinguish the fire. However, firefighters should be aware of the corrosiveness of water dissolved in granular alkali.
