1. There are many types of protective gloves, which should be selected according to the protective function. First of all, you should clearly identify the object of protection and then carefully select it. Such as acid and alkali resistant gloves, resistant to strong acid (alkali), resistant to low concentrations of acid (alkali), but resistant to low concentrations of acid (alkali) gloves can not be used to contact high concentrations of acid (alkali). Remember not to misuse it to avoid accidents. 2. Waterproof, acid and alkali gloves should be carefully inspected before use, observe whether the surface is damaged, take a simple approach is to breathe in the gloves, hand tightly cuff, observe whether the leak. Leakage can not be used. 3. Insulating gloves should be regularly tested for electrical insulation performance and cannot be used if they do not meet the requirements. 4. Rubber, plastic and other protective gloves should be washed and dried after use. Avoid high temperatures during storage and sprinkle talcum powder on the product to prevent adhesion. 5. Contact with strong oxidizing acids such as nitric acid, chromic acid, etc., due to strong oxidation can cause protective gloves brittle, discoloration, early damage. High concentrations of strong oxidizing acids may even cause burns and should be observed. 6. Latex industrial gloves are only suitable for weak acids, low concentrations of sulfuric acid, hydrochloric acid and various salts, and must not be exposed to strong oxidizing acids (nitric acid, etc.). In the power telecommunications industry, workers encounter various types of live operation. According to the actual operating voltage to select the appropriate electrical insulating gloves, and in actual operation, should use electrical external gloves and electrical insulating gloves together to better protect the puncture and tear hazards. Before and after each use of electrical insulating gloves, the necessary checks should be carried out to ensure the safety during use. 　　 Protective sleeve Protective sleeves are used to protect the hands of the arm. There are: 1. Asbestos radiation sleeve: used in high temperature furnaces and other workplaces. 2. Aluminum film insulation sleeve: used in high temperature furnaces and other operating environments with strong radiant heat. 3. Anti-acid and alkali-coated sleeves for blankets: used for contact with water, acid and alkali, dirt, etc. 4. Plastic acid and alkali resistant sleeves: used for contact with water, acid and alkali, dirt, etc. (China Labor Insurance Network)
