I was controlling the work that some steeplejacks were doing on our flarestack which is about 300ft high. they had been working at a height of about 70ft when their boss came down and said there was a problem with the steel floor at that level and I should take a look, I climbed up there with him, and he showed me some corrosion on the floor, it didn't look to bad ,he then said"it's only over there here is fine" at that he dropped the hammer he was holding at our feet, it went straight through the floor!!!!!
we both grabbed the handrail and screamed "foook get the fook down"!!!!
got back to my office looking white as a sheet!
