"they" really don't want us to work.
day job is senior network engineer, we have a lab where we evaluate new equipment. There is both 110 and 220 PDUs located in equipment racks, been that way for 25 years. A couple weeks ago someone, who was escorted by a regular into the lab, plugged 110 power strip into 220 PDU, tripped lab breaker. First time this has ever occurred, 'cause regulars know the difference.
We had to have a meet with safety regarding the incident. Safety engineer first suggested we move all the PDUs to their own racks, and run power in NEW overhead cable trays. They grudgingly accepted labelling voltage on the different PDUs. I gave up trying to explain everyone working in the lab should recognize different receptacles and we should hold the person who escorted the idiot responsible The escorting individual ended up getting rewarded for writing a good lessons learned document. We don't hold anyone responsible for bad decisions any more.
