Why should not you run a cord under a rug?

Running a cord under a rug can pose several safety hazards, including the risk of electrical shock or fire if the cord becomes damaged or overheats. Additionally, the rug can create a tripping hazard, increasing the likelihood of accidents. It can also lead to wear and tear on the cord, reducing its lifespan and potentially causing malfunctions. Therefore, it's safer to use cord covers or keep cords in designated areas to prevent these issues.
