LOUISVILLE, Ky. (WDRB) -- Taking a free, 10-minute class could save another person's life.

The "Be Smart.Start a Heart." CPR Challenge, sponsored by Clark Memorial Hospital, was offered at six southern Indiana fire stations on Saturday.

Firefighters taught community members effective and efficient chest compressions.

It's part of the American Heart Association's hands-on CPR program.

"Everyone needs to know what to do if someone does collapse and go down," said Carolyn McKee of Clark Memorial Hospital.

"It's our foundation for cardiac arrest victims," said Brandon Skaggs, Chief of the Clarksville Fire Department. "It's the greatest intervention that firefighters, lay rescuers, police officers -- anyone -- can provide outside of pre-hospital care."

Chief Skaggs says everyone should learn the life-saving skill, because you never know when you'll need it.
