When storing solid caustic soda in a chemical laboratory, the reagent bottle should be sealed to prevent exposure to air, absorption of moisture and deliquescence, or reaction with carbon dioxide. In addition, when glass bottles are filled with caustic soda or other forms of sodium hydroxide, do not use glass stoppers, but use rubber stoppers, as caustic soda will react with silica in the glass to form sodium silicate. The bottle stopper and body are not easy to open. Caustic soda can be prepared by electrolyzing salt solutions or reacting sodium carbonate with lime milk.
Workers operating caustic soda are susceptible to the risk of caustic soda flakes. Require these employees to wear protective clothing and equipment before going to work, and request the company to provide safety shower and eye wash equipment. Caustic soda is prone to leakage during the production process. Emergency measures should be taken to cut off the disclosure of the purification area and limit revenue and expenditure in case of caustic soda leakage.
That's all for this issue. First aid personnel should wear dust masks and acid and alkali resistant clothing. It is strictly prohibited to wear appropriate protective clothing to prevent container damage and leakage. Try to intercept the source of the leak as much as possible. Cover this disclosure with plastic sheets to reduce scattering. Do not let water enter the caustic soda packaging container. Collect disclosure information with a clean shovel, place it in a clean, dry container with a loose lid, and then remove the container from the disclosure area.
