Last time I did outdoor physical work in Texas was in the Army at Fort Hood. Here are the Army guidelines on work/rest intervals and fluid intake: https://www.moore.army.mil/MCoE/MCoE-Safety/content/PDF/Heat%20CAT%20Fluid%20Consumption%20Guide%20%202015.pdf https://www.moore.army.mil/MCoE/MCoE-Safety/content/PDF/Heat... Central Texas has been straddling that red/black line for the past month, and I suspect this would be classified as "moderate work," so that would require 40 minutes of rest for every 20 minutes of work. Thankfully, Gov. Abbott cannot make it illegal for the Army to enforce this.
