Think carefully about whether you will be siting your defibrillator inside or outside. It is always preferable for the defibrillator to be located where it can be publicly accessed if possible. Think about where most people would be able to access the device, whether it will be accessible 24 hrs a day and if the area is well lit. A prominent and visible place but one which is not overly exposed to the elements is often best. 

Think about who might need to access the defibrillator and ensure you place it as a suitable height. Think about access routes and ensure there are no obstacles which might prevent access in an emergency.
