A voluntary group has raised the money to purchase 12 defibrillators, three of which have already been installed.
The Kerry town has a population of around 12,000 which can treble with the influx of visitors during the peak tourist season.
The defibrillators will be placed at different locations, including shops and hotels. Siobhan Linehan set up the Michael Linehan Heartsafe Committee to provide the equipment after her father Michael died from a heart attack.
She joined forces with Killarney Lions Club, which was also in the process of providing defibrillators, and a committee has beenworking for the past yearon providing essential training and buying the equipment.
“One of the main things we wanted to ensure was that the equipment would be easily accessible to the public,” Ms Linehan said.
The Michael Linehan Heartsafe Killarney Committee organised three day’s training in conjunction with the Irish Heart Foundation.
Over 150 people in the town are now qualified to use the equipment when emergencies occur.
The defibrillators are being placed at the following locations: Killarney Court Hotel, St Mary’s Cathedral, Market Cross, Taxi Rank, Cineplex, Daly’s Supervalu, Ilona Louise, White Gates Hotel and Hegarty’s, Muckross Road.
The organising committee plans to continue fundraising for additional machines and to pay the ongoing costs.
