Re: wind direction
You have raised an excellent question about wind direction. It reminded me of my first days as an electrical apprenice in a large chemical plant.
The first rule when we went on a job, was to check for the wind direction, and I can tell you from experience that it is a good rule to follow.
You do not have time to find a wind sock and determine which way that the wind is blowing. I might add, I did not walk, we ran, and I was always out in front. This situation happened two times in my long career.
