I'm sure you are right about that. My field was industrial electronics. Safety protocols were strictly adhered to - for that. Now and again we encountered a few rather ...um 'surprising' instances. One such was a variable speed drive lashing in the rain. That is outside with no external covering. Madness. Fortunately, the customer and lads survived. The drive was not so lucky.I suspect we will find eventually that no safety protocols that were followed at all. They just went in because they done it a hundred times before and nobody had ever died before so obviously it was safe. This is the kind of thinking that gets people killed on a regular basis.
