FORT WORTH -- Just past noon on Tuesday MedStar units were rushing to three simultaneous calls for heat distress.
That's one-sixth of the calls at that time. One young man went down while hanging door fliers in a Fort Worth neighborhood.
"He's walking door-to-door. He collapsed. Had a blackout," said Lee Brown, who came by to pick up the man in a van. Brown pulled him into the air conditioning.
"He said he was dizzy. He felt like fainting," said Brown. "I stopped a couple times. He kept puking. So eventually I'm like dude, I'm calling an ambulance. I ain't having somebody die on my hands."
MedStar took the man to a hospital.
Meanwhile another MedStar unit was responding to a man who succumbed to heat while working with tractor trailer rigs in a parking lot.
"Firefighters said it was about 125 degrees, estimated," said MedStar supervisor Jimmy Aycox.
The metal and concrete turned the lot into a stove top. That man also was transported to a hospital.
As of July 23, MedStar had responded to 169 heat calls. That's nearly 40 percent more than last year. The Tarrant County Health Department reports 52 hospital ER visits for heat.
By 4 p.m. Tuesday, MedStar had rolled on 11 calls for heat exposure. And there was still plenty of heat left in the day.
