How to use, store and maintain electrically insulated shoes?

1. Insulating shoes are designed to be used as auxiliary safety equipment and personal protective gear when working on electrical devices operating at AC 50Hz with a voltage of 1000V or less, and DC up to 1500V. These shoes allow workers to safely approach live parts when using basic tools, and they help protect against electric shocks caused by step voltage. Step voltage occurs when there is a potential difference between two points on the ground, typically 0.8 meters apart, due to a fault in grounded electrical equipment.

2. It is important to keep insulating shoes dry at all times. If they become damp, do not use them immediately. Instead, place them in a well-ventilated area to air dry naturally. Avoid exposing them to moisture, as this can damage the leather and reduce their insulating properties. If the soles are punctured by foreign objects, the shoes should no longer be used as insulating footwear.

3. Proper maintenance of leather shoes is essential. Use shoe polish regularly to maintain their appearance and durability. To apply the polish, first wipe the surface with a clean, soft cloth to remove dust. Then, apply a small amount of shoe polish evenly onto the cloth and gently rub it onto the shoe surface. Allow the polish to slightly dry before buffing it to a shine.

4. Avoid wearing leather shoes in rainy conditions or washing them directly with water. Doing so may lead to cracking, peeling, discoloration, or other forms of damage. Always keep them away from rain and excessive moisture.

5. Do not expose your leather shoes to oil, acids, alkalis, or sharp objects, as these substances can cause corrosion, deformation, or physical damage to the material.

6. When wearing colored leather shoes, especially white ones, be cautious about where you walk. Avoid stepping into sewage, dirt, tea stains, or cola spills, as these can leave permanent marks and affect the original color of the shoes.

7. It's normal for leather shoes to show slight folds or minor deformations after being worn. This does not affect their quality or functionality.

8. After exposure to moisture or sweat, leather shoes may develop a white powdery substance known as "pan-salt cream." If this happens, gently wipe the affected area with a damp cloth soaked in warm water, then place the shoes in a ventilated area to dry. Apply shoe polish and repeat the process several times until the appearance is restored. Keeping your shoes dry is crucial to maintaining their condition.

9. When storing leather shoes, ensure they are clean, dry, and properly polished. Store them in a cool, dry, and well-ventilated place. During the rainy season or after long periods of storage, occasionally air them out and reapply shoe polish to prevent mold growth and maintain their quality.
