Defibrillators can be fitted where they can be accessed by yourself and your staff, or alternatively (and more common nowadays) is to fit a public access defibrillator
With a public access defib, the unit is located within a cabinet which would be accessible to everyone. The cabinet has a 'code lock' on the front, and the ambulance service will give the access code to a caller in the event of an emergency which would require the defib.
Public access defibrillators can be installed within buildings, on the external wall, or a popular choice is to install within old telephone boxes.
Unused telephone boxes can be allocated to community projects by BT. These can easily be converted into defibrillator boxes and most (if not all) already have the power supply ready for the cabinet. Not only that, they often have a light fitted above which means that the cabinet can be accessed easily in the dark.
Of course, public access cabinets need to be registered with the Yorkshire Ambulance Service. Doing this means that the call handler can give critical information to an emergency caller should the need arise.
Yorkshire Ambulance Service can provide full details of the most appropriate model to purchase if you are looking to go down this route and we would be happy to advise on the fitting of such a cabinet free of charge.
