At that point Bay Networks had not existed for over a decade.

The owner got mad when my employer cancelled the annual fixed-price maintenance contract. But we had no choice, because the last time we repaired it under the contract, the replacement component required was the last one. In the world.

maybe because you *have* to keep an eye on it, and it encourages maintenance staff to check that its usable (and not block the wire with any items).

The same area is shared with the 400V three phase incoming service cable (which isn't as common nowadays - instead the gas and electricity supplies are in different parts of the building)

When I worked on maintenance team for senior homes, we had this in one of the boiler rooms (I am short and the wire is exactly at neck height for me - so I always had to beware of it.

But there is good reason for it being present, there's a lead link at one end and a pulley and weight ; if a fire starts the lead would melt, and then the weight pulls down the lever and shuts off the gas supply to the building (to prevent gas feeding the blaze)

Is he still doing it?
