Electrical Safety: An electrical disconnect box at the Radioactive Liquid Waste Treatment Facility was recently found to contain a length of metal conduit deliberately installed in place of an electrical fuse. The circuit did have over-current protection upstream, but laboratory management is appropriately treating this discovery as a serious event. The institutional electrical safety committee has been consulted and a plan is being developed to perform sampling inspections to characterize the extent of condition. In addition, this event appears to be spurring action to catalogue, prioritize and systematically address other legacy electrical code compliance issues and known deficiencies.I'm curious what other circuits would have lost power, and for how long, had the next upstream device tripped? Failed to trip? Also, was the next upstream device LANL's or the utility's?
Did KSL install this "fuse" (and how long was it in service)? If so, I think I know why they were kicked off site.
[The fuse in the photo is just an example, not the fuse described in this post.]

Rumor has it that his name is Sparky.
I prefer to look at the bright side. (no pun intended). A serious deficiency came to light (again no pun) and the light was shown on it (you get the point). It wasn't covered up.
How many other fuses are out there? And where might they be? Sabatoge???
To 4:05 PM: there was a PADOPS report issued about another finding at TA-46 ...
Sabotage? Doubtful
Incompetence? Likely (especially if KSL did the work.)
Sabatoge or sheer stupidity the end result is the same.. This could prove deadly to some poor soul.
"Also, was the next upstream device LANL's or the utility's?"
LANL is its own utility...KSL does hands-on operations of the whole thing down to the wall socket.
In the picture it looks like a fuse, just a different color.
I don't have a picture of the actual "fuse". This is a photo I found on the web.
If anyone has a photo please send it in.
The "fuse" likely is a piece of conduit with the ends smashed flat to fit in the spade lug fittings. Or it could even be a piece of flat stock cut to length and shoved into the fuse holder.
