Strange Socket In Hospital

[Harry Bloomfield]

Not forgetting of course, the quite deadly plugs they once used, which used a screw in cartridge fuse, as the plug pins.

Shouldn’t the sign say “left hand socket” not “left hand plug”

I did some work for a geezer who called every accessory a plug, light switch, cooker point, also pronounced conduit "condwee"

Dorman Smith? why were they deadly

The fuse/plug pins, used to unscrew, leaving a live fuse end, poking out of the socket.

How could it 'unscrew' whilst in was engaged with a socket?

The place I served my apprenticeship used D&S sockets and plugs, never saw that happen in 10 years

They did, I can assure you... Plug in, with the fuse almost on it's last thread, remove the plug, and the last thread was ripped off, leaving the fuse in the live socket.

Fair enough, but I think that counts as 'improper use' in my book!

The design was flawed, it was just far to easy to end up in an unsafe condition, if the thread became weak, or the fuse cracked - leaving live parts poking out of the socket, after unplugging.

When you return see if there's others located, that's a newish logic plus and as you say the sign looks old and possibly older than the original logic range.
I would also expect it to have outboard rocker switches in a hospital environment
Maybe if recent even a grey microbial socket

Interesting comment. Why do you say that ?

A lot of the medical sites we do have them, apparently it aids the staff who often wear some form of gloves
It allows them easier switch operation as well as preventing operating both switches inadvertently,.
Moreso for the corridor sockets that cleaners use

Interesting. Maybe it's always been like that and I haven't really 'noticed'!

I'm a radiographer. Our portable xray machines all run off internal batteries, which can be charged from any 13a socket. The high kV mA is all provided by the batteries, doesn't need to be plugged in to expose.

Thanks for confirming. Although my direct knowledge dates from times gone by, my understanding of the presentday situation is as I described at the start of this discussion, when I wrote:

..... However, I think modern kit actually runs off internal batteries, and therefore doesn't necessarily need a power supply at all when in use.

However, what about modern portable image intensifiers, which is what most of my (now very dusty!) personal experience related to? Since they can be required to generate X-rays continuously for quite long periods of time, rather than for just a very brief exposure, I would imagine that they would be hard-pressed to work for long off internal batteries?
