Still, techs who work in unconditioned attics and on open rooftops are in potentially dangerous situations due to the heat. John Ambrosino, of Total Temperature Control (Wakefield, MA), put it this way: “I like the people I work with. I don’t want to kill them.”
The sickest he’s seen a technician get on the job? The guy was “vomiting, hot and dry, ashen colored, had diarrhea, and was weak and wobbly” — very sick indeed. Following good heat prostration procedures would have prevented some of these effects.
