I see this ALL THE TIME in the power plants. When they close up the entry ways into the boilers at the end of an outage, the "hurry up" attitude is at the maximum "get someone killed" volume. Fake studs are common. I've even seen them tacked to the FRONT on the access door. Of course the nut will cover it up.
This is the kind of crap work being done today in the USA. The sad fact is that nobody seems to care as long as the power plant gets back on line faster than the last outage. The bodies are piling up people. When will it stop? Did anyone see this story from Vegas? Six people died on one job, in seperate incidents, at a Casino building site. It was so bad that they went on STRIKE over it. This was a UNION job!
