Sodium hypochlorite is a common disinfectant, and the following points should be noted when using it. Firstly, carefully read the product manual before use and follow the instructions for concentration and usage. Secondly, attention should be paid to protecting the eyes and skin during use, avoiding direct contact. Again, sodium hypochlorite is oxidizing and should not be mixed with other chemicals to avoid dangerous reactions. In addition, sodium hypochlorite has a certain degree of corrosiveness, so it is important to avoid contact with metal surfaces during use to prevent damage. Finally, after use, residual sodium hypochlorite should be properly stored away from children and avoid exposure to sunlight to prevent failure. In general, the correct use of sodium hypochlorite can effectively disinfect, but it is necessary to pay attention to safe use and follow relevant regulations.
