Correct use of insulating shoes and precautions for use
Insulated shoes are a kind of safety shoes made of insulating materials. They are used as auxiliary safety devices for preventing electric shocks to the feet when working in the electric field. The use of insulating shoes should follow safety regulations, so as to play the maximum protective effect. So what are the correct use methods and precautions for insulating shoes?
The scope of application of electrical insulating shoes is clearly pointed out in the new standard: electrical insulating leather shoes and cloth electrical insulating shoes with a withstand test voltage below 15KV should be used in an operating environment with a power frequency (50-60F) below 1000V, and a test voltage above 15KV. The city's electrical insulating rubber shoes are suitable for working environments with a power frequency of 1000V or more. The following items should be paid attention to when using insulating shoes:
1. Check whether the insulating shoes are damp. It is strictly forbidden to use them after being damp. Once damp, they should be placed in a ventilated, ventilated and cool place to dry naturally before use;
2. Check whether the insulating shoes are damaged or leaked. When the soles are pierced by foreign objects, they cannot be used as insulating leather shoes and should be replaced;
3. Insulating shoes should not be worn in rainy days, and should not be washed with water, otherwise it is prone to disconnection, degumming, decolorization, salt frost and other phenomena;
4. Insulating shoes should not be in contact with oil, acid, alkali and sharp substances to prevent corrosion, deformation and damage;
5. Insulating shoes that are not in use for the time being should be carefully cleaned of dirt, sludge and dust, and then carefully painted with shoe polish. When storing, the shoe polish should not be applied too much. If it is applied too much, it will cause the leather surface to be brittle if stored for a long time. When storing, it is best to apply a little raw chicken oil, raw lard or glycerin to keep the leather surface soft and moist without deformation;
6. Pay attention to the maintenance of the leather surface of the leather shoes, and polish the shoe polish frequently. The wiping method is: first wipe off the dust on the surface of the leather shoes with a clean soft cloth, then squeeze the shoe polish on the cloth and apply it evenly on the shoe upper, wait for a while (the shoe polish is slightly dry) and then wipe.
