What hazard is associated with flexible cords in excess of 50V being attached with plastic rigid ties to metal structures?

Flexible cords that exceed 50 volts being secured with plastic rigid ties to metal structures pose a significant risk due to the potential for mechanical damage. The primary concern here is that the plastic tie can apply pressure on the flexible cord, especially if there is any movement or vibration in the metal structure. Over time, this pressure can cause the sheathing of the cord to wear down, leading to exposure of conductive materials inside the cord.

Once the sheathing is compromised, the electrical conductor may come into contact with the metal structure, which could energize the structure and create a shock hazard for individuals nearby. This scenario underscores the importance of proper securing methods that do not risk damaging the protective insulation on electrical cords. Proper awareness and adherence to safety standards are crucial to prevent electrical hazards in maintenance and operational contexts.
