• Unplug unused appliances and store cords safely out of reach of pets, young children or hazardous situations.
• Appliances that generate heat, such as clocks, televisions and computer monitors, should be given several inches of clearance all around for good air circulation and cooling. 
• Keep all electrical appliances away from water such as sinks, bathtubs, pools or overhead vents that may drip.  Be sure all outlets around these areas are protected by GFCI's.
• Do not operate any electrical appliance with wet hands or while standing in water.
• Cords should be firmly plugged into outlets - if the cord is loose and can pull out easily, choose a different, more snug outlet.
• Cords should not be placed beneath rugs where they can become a trip hazard or where frays will not be noticeable. Furthermore, covering a cord will prevent it from keeping as cool as possible.
• Every cord has to plug into an appropriate electrical outlet, but these tempting niches are inviting to unwelcome objects that can cause shorts and fires.
• Do not overload outlets with multiple adaptors or power stips; relocate cords instead.
• Install ground fault circuit interrupter (GFCI) outlets in potentially hazardous areas such as near pools, crawlspaces, kitchens and bathrooms.
• Keep trees pruned and away from power lines overhead as well as where the power lines approach the house.
