So you check the power cables for every device you interact with in the office?
I've known people (some got quite senior) who wouldn't notice that their monitor was on fire.
Seniority doesn't imply that they're not dumb! Educated idiots are everywhere.
All our office equipment plugs in to dado trunking and so cords etc. are visible (and very nicely cable managed by our IT team and other equipment by our sparkies).
We do this to prevent snags under desks and people accidently pulling cables out with their feet.
