I worked as a temp for a corporation in Gordonsville that made custom tee shirts by sealing the logos/pictures onto the tees in a huge warehouse.  When the temperature rose in the summer, it was unbearably hot in there.  I was an office employee, and know I wouldn’t have lasted half a day in that environment.  There had to be outside ventilation because of the toxic nature of the work: fusing plastic onto cotton at high temperature through applied pressure.  They brought in so-called A/C blowers, but they were ineffective in that heat.  Only the young and hardy could do this work.  I felt it was asking for a fatality.  Thins in this factory setting should be changed so the work can be done more safely.
