Christmas Lights can be beautiful but can also be a danger.
Christmas Lights can easily be flammable if over done. Make sure when hanging lights that the lights are not stacked on top of each other. Also, make sure all cords are checked for any loose or torn wiring.
Not only can Christmas Light be a fire hazard but they can also be a danger to hang up. Make sure before hanging the lights you review the instructions for setting the ladder up properly and have someone there to spot you as you hang the lights.
