Cable management is treated as tidiness and several parts of it are genuinely about safety.
Nothing Across a Walkway
The rule that matters most. A cable running across a floor where people walk is a trip hazard, and trips over trailing leads are a recognised cause of injury at home and at work.
It matters more in a room crossed in the dark, and considerably more for older people or anyone with mobility difficulty.
Route along a wall, or overhead, rather than across.
Furniture With Power Built In
Sofas and nightstands with integrated charging remove one trailing lead and add a mains lead of their own.
That lead should go into a wall socket rather than a shared extension, should not be pinched under a leg or by a mechanism, and should not run under anything. Where ranges list charging as a feature, of the kind at stellamia.org, checking where the lead exits is worth doing before the piece is against a wall.
Never Under a Rug
- Foot traffic damages the insulation where you cannot see it
- The covering traps heat that would otherwise dissipate
- Both together are a genuine fire risk rather than a theoretical one
- A cable under a rug also creates a ridge, which is its own trip hazard
- There is no version of this that is acceptable
Extension Leads
Never daisy-chained, meaning one plugged into another. Each has a rated capacity, and chaining them is how the rating is exceeded without anybody noticing.
A fully coiled extension lead under load can overheat, so unwind it rather than leaving it wound on its reel.
Anything with damaged insulation, a cracked casing or that becomes warm in use comes out of service rather than being taped.
Sit-Stand Desks Need Slack
The specific case. A desk that moves needs cables that travel with it and enough slack at the highest position.
Cables pulled taut by a rising desk is a common way monitors get dragged off and connectors are damaged. Routing everything through a tray that moves with the top solves it.
Under-Desk Trays and Knee Room
A tray or a power strip mounted under a desk frequently takes the clearance you need to sit properly.
Mounting it toward the back rather than the front keeps the knee space, and keeps the chair able to get in.
Charge in Open Air
Not in a closed drawer, not under a cushion, and never under bedding.
Label Both Ends
The practical tip. Small tags on each cable saves crawling under a desk to find out what unplugs what.
Leave It Accessible
Cable management so thorough that nothing can be unplugged is its own problem.
