On April 1, 2009, Scott Luck, a foreman at CentiMark Corp., Canonsburg, Pa., was working on a roof in Chippewa, Pa., when one of his crew members, Keith Arnold, seemed to have trouble breathing.
"He's an older man and stubborn, but the more I thought about it, it just didn't seem right," Luck says. "He was able to make it down the ladder, so I took him to the hospital. When we got there, we found out he wasn't in good condition, so he was transferred to another hospital. He lives close to me, and I've known him since I started here, so I sent my wife to his house to get his wife so she could meet us at the hospital."
Arnold had suffered a heart attack, but Luck's quick action helped lead to Arnold's recovery.
"It was a stressful day, but it all turned out OK," Luck says.
