In the past the biggest concern with operating an overhead garage door was the potential risks associated with the springs used for balancing the door weight. Pre mid 1960s garage door installations typically relied upon a pair of stretched (tensioned) springs to assist the operation of the garage door pivoting hinges. These springs became loaded (tensioned) as the door was moved into the closed position. Unloading (releasing) of the stored spring energy occurred as the door was opened to the horizontal overhead position. One of the most dangerous aspects of these spring systems was that after a period of time often without any maintenance or inspection the points of attachment of these springs would rust or become weak.

The date is January 27 2011 and the time is early in the middle of the night. In Dallas TX a family lies quietly sleeping- a husband a wife and their little daughter. In the early hours of the morning the wife awakens and stumbles out of the bedroom to check on their daughter. Perhaps subconsciously she heard a noise. As she walks through the house she notices that the lights in the house were left on. How strange she thinks to herself. In her half awake half asleep stupor however she doesnt think too much of it. Then she notices that the door from the house to the garage was also open and as she walks closer she can see that the garage door is open as well.
With a torsion type of spring the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation the complete loading of the torsion spring is controlled by the garage installer and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained unqualified individuals have attempted to install or service this type of spring.
