It was on all 4 of the ships I was on. And we removed and replaced a bunch of it in the engine rooms. OSHA did’t exist when I was in.
I never made it to a float. East coast, West coast, and Japan...
At one point, I had orders for Bahrain (via a 2 day layover in Rota, Spain)... but those got cancelled and I ended up in Japan instead... Go figure...
