There are no
PAD» defibrillators available anywhere in Hayes or surrounds, least of all at any train stations. Not even at Heathrow.
https://www.bhf.org.uk/how-you-can-help/how-to-save-a-life/defibrillators"There are many defibrillators available in public places such as train stations, shopping centres, airport and leisure centres. These defibrillators are often known as public access defibrillators (PAD) as anyone can use them in an emergency. You shouldn’t be afraid of using a defibrillator if someone has had a cardiac arrest."
Huh - not in our area.
