Sweltering summer temps renew concerns about worker safety

Last week's record-breaking heat wave is highlighting concerns about the potential health risks facing workers.

At Northside Hospital Forsyth in Cumming, Georgia, Dr. Douglas Olson, the medical director for the emergency department, said he's seen a roughly 20% increase in heat-related visits since last year across the hospital's five systems. "Most of the time it's related to occupational heat exposure," he said. "So those people that are working outside for prolonged periods — it's been pretty rough."

The brutal temperatures in Atlanta led the death of one outdoor worker, Olson confirmed.
