Britain's red phone booths have been converted into mini-community libraries or book exchanges. Now some are being turned into life-saving house defibrillators. From Cornwall to Shetland, more than one thousand such red phone boxes were repurposed by the Community Heartbeat Trust and BT. Phone booths are ideal for the job as they provide a heated cabinet to protect against cold weather. “As telephone kiosks are in the center of communities, and are easily recognizable and generally feature on OS maps and satnavs, these make great locations for defibrillators," said Martin Fagan, National Secretary of Community Heartbeat Trust.
