Walk through your home and search for potential electric hazards. Many hazards are easily identified and corrected.
Never put items into electric outlets that are not intended for them.
Make sure electric outlets aren't overloaded.
Check all electric and extension cords to make sure they aren't cracked, frayed, or covered by rugs or furniture.
Use the correct wattage light bulb for lighting fixtures.
Keep electric appliances away from damp or hot surfaces, and make sure they have appropriate air circulation.
Signs of potential hazards that should be examined by a qualified electrician include dim or flickering lights, arcs or sparks, sizzling or buzzing sounds from your electric systems, odors, switch plates hot to the touch, loose plugs, and damaged insulation.
