Christmas decorations are not cheap and it is best to invest a little bit of money into buying decorations, and get a better quality decoration when it involves it to be outside enduring the weather.
When purchasing lights or animated decorations be sure that they are ULC (Underwriters Laboratories) approved for that added safety.
Most outside outlets should be GFCI double check to make sure the ones you are going to use are.
Extension cords are a must when hanging decorations outdoors.
Be sure that they are also rated ULC and that you do not overload a single cord.
Inspect them to make sure they have no signs of major wear, no wires are exposed.
Make sure they can handle the amp load of the decorations you will be hanging.
Make sure the decorations are out door use.
Most will say on the box and have a list of specifications for hanging outside.
If it does not say check the manufacturers website or ask a employee for some help.
Ladders.
You will probably need at least a 6 foot step ladder, and maybe a extension ladder, depending on your house.
Before you start inspect your ladder to make sure that it is in proper working order and not falling apart.
Make sure you always have the ladder properly planted before beginning to climb up.
A great tip is to have someone else help you when hanging your decorations as they can spot you while you are on the ladders.
Just be sure to use your head while hanging your decorations.
Make sure you are safe and keep everyone that will be enjoying your decorations safe as well.
Christmas is a time to enjoy with your family, and taking a trip to the ER is not a way you would want to spend your holidays.
