Sounds like somebody needs to be packing more water with him.
When the heat ends up getting to one of the guys on the crew, they are put in the shade, or truck with a/c and some water. Pretty much they are in Time-out an not allowed to leave the shade/AC until one of the Boss's says to, then he's on light duty for the rest of the day.
However since were all working together, its pretty obvious when somebody is having an issue with the heat or anything else. And can ussually be caught before things get to serious.
