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 voltages up to 1000V and DC voltages up to 1500V, with a frequency of 50Hz. These shoes are essential when handling live parts with basic electrical tools, as 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 crucial to keep insulating shoes dry at all times. After use, avoid exposing them to moisture. If they become wet, allow them to air dry in a well-ventilated area. Never attempt to dry them using heat sources or direct sunlight, as this can damage the leather. If the sole is punctured by foreign objects, the shoes should no longer be used for insulation purposes.

3. Proper maintenance of leather shoes is important for both appearance and functionality. Use shoe polish regularly to keep the leather in good condition. To apply it, first wipe off any dust with a clean, soft cloth. Then, apply a small amount of shoe polish evenly onto the cloth and spread it over the surface of the shoes. Let it sit for a few minutes until slightly dry, then buff with a clean cloth for a smooth finish.

4. Avoid wearing leather shoes in rainy conditions or washing them directly with water. Doing so may cause cracking, peeling, fading, or other forms of damage. Always ensure that the shoes remain dry and protected from excessive moisture.

5. Keep insulating shoes away from oil, acids, alkalis, and sharp objects. Exposure to these substances can lead to corrosion, deformation, or physical damage, which may compromise their protective qualities.

6. Be especially careful when wearing colored leather shoes, including white ones. Avoid contact with sewage, dirt, tea, cola, or other staining substances, as they can leave permanent marks and dull the original color of the leather.

7. It is normal for leather shoes to show slight creases or minor deformations after extended use. This does not necessarily indicate damage or reduced effectiveness.

8. When shoes get wet or sweaty, they may develop a white residue known as "pan-salt cream." If this happens, gently wipe the affected area with a damp cloth or gauze soaked in warm water. Dry the shoes in a ventilated space, then apply shoe polish and repeat the process several times to restore the original look. Keeping the shoes dry is key to maintaining their quality.

9. Store leather shoes in a clean, dry place with proper ventilation. Apply shoe polish regularly to maintain their appearance and prevent mold, especially during humid seasons. Periodically check the shoes and reapply polish to ensure long-lasting protection and comfort.
