I wonder what'd happen to puke if it falls from up there.
I have some experience of that. It sort of fragments and rapidly disappears into fresh air. Some of it goes up and away in the updraught.
When I was younger I worked a shutdown once as a mech-fitter on an ICI tower that overlooked Blackpool tower (it's just outside Blackpool). It was billed as the tallest Chemical plant tower in Europe at the time. Me and my mate Moose were given the job because we were the fittest in our firm: I was running 6 miles per day after work and doing 200 push-ups, pull-ups and leg presses, before we went out for a beer.
Our main dread was either forgetting to take up a spanner (wrench) of the right size or else dropping a tool onto anyone working below on any of the many levels, in the plant, below the reactor mast. The wind up there made the mast sway and motion sickness was a definite problem. So was having to use both hands at once to hold tools, say a hammer and a spanner. We worked out a system whereby one of us used one of the tools and the other the other tool. It helped that I'm left-handed and Moose was right-handed. Any unlashed tools slid from side to side across the small platform we perched on.
We wore a full set of waterproofs, safety helmet and gloves, and lashed our toolbags to our backs. We sweltered all the way up and , in those days, had no clip-on safety harness, just a rope to wind your leg around when you wanted a breather, run down the inside of the ladder guide.
Like the guy in the pix, we never thought it anything unusual and looked forward to the stunning views from the top.
