Here's why:
* Rubber is an insulator, but not a perfect one. While rubber resists the flow of electricity better than many other materials, it's not a complete barrier. If the voltage is high enough, or if the rubber is damaged or worn, electricity can still pass through it.
* Slippers are not safety footwear. They are not designed to protect you from electrical hazards. They can actually create a false sense of security, leading you to take risks you wouldn't otherwise.
* Proper footwear is essential. When working with electricity, you should always wear insulated shoes that meet safety standards. These shoes have thicker, more durable soles that offer greater protection against electrical shock.
Always prioritize safety when working with electricity. Never assume that any material, including rubber, will completely protect you. Consult professional resources and follow safety guidelines for your specific situation.
