Damaged socket found in kick plate cable system under a desk.
Possibly damaged by vacuum cleaner or shoes / boots.
Danger of injury from contact with live parts is obvious. Also fire risks if water or insects or small animals enter the socket and connected system.
Easily repaired relatively cheaply by a qualified person.
Damaged probably would not have been found without a regular inspection as it’s easily hidden by bags, shopping, office supplies or work samples.
