I know an old lad that lost the end of 2 fingers to a sheet that slipped down the wall as we was sorting the bottom sheet, I also dropped a tek gun on his head from 2 lifts up, (old fashioned big heavy gun) put him on his knees, I was pretty young 21 maybe, he was in his late forties then.. f**k he kicked off... I couldn't breathe for laughing.
When we first started on the steels we walked the lot, up over the rafters etc, no machines (lots on farm jobs) looking back we were mad to do it, no nets under the roofs which is compulsory now, the first job I ever had nets on was a massive unit
