Did a job there a few years ago in the summer. I'd worked there before off and on for years and knew what to expect. I had a young ambitious welder with me and he darn near killed me busting azz in the heat the first day.
Got back to the hotel that evening and I explained the rules to him.
Next day we started at 5AM, worked till 9AM then quit and went back to the hotel.
Took a cool shower and headed for the pool, swam for a while and took a nap.
We went back to work at 4PM and worked till 8PM
That was my normal workday in Arizona.
I never liked keeping my tools in a bucket of water.
