That brings back memories.
That's the sort of stuff I used to do in what now seems like a past life. I worked at BHP, power stations, coal washeries, fertilizer plants, food processing plants and quite a few other production plants.
I was an industrial slut, I went wherever the money was and put my body on the line. I had more brushes with death than I care to remember.
That sort of work is almost non existent around here these days.
