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.
