An electric fence can be a great way of keeping unwanted animals out of a garden. Since it utilizes electricity, there are a few things that will help ensure the safety of those who enter the garden. The fence itself should be well marked and the use of a warning sign at the entrance will help to alert people who may not know that it is electric. Secondly, proper instruction should be given to those who will enter into the garden. Finally, the wiring and power supply for the fence should be properly grounded and installed.
