Working in the shipyards.
One of my fun tasks was prepping pipe (up to 60” x 20’) for shipment overseas. I had to take a mop and coat the pipe with Cosmolene, a tick, goopy mess. I also got the clean the weld slag from the inside of boilers - that’s where I learned that I have claustrophobia.
Ugh, me too. Can you handle airplane flights? I can't.
