Extension cords are not meant to be permanent installations. However some people overuse them to a potentially dangerous level. When grounded electrical cords are used with a cheater and plugged into an ungrounded device the danger is increased. We were called to a Mount Airy home recently that was using this exact set up. What prevented a potential fire was the cheap plugs melting off of its metal connections. To avoid this dangerous situations you can avoid using extension cords and have a qualified electrician install grounded outlets in places you need them.
