This weakening of the springs or points of attachment would often lead to an inadvertent explosive failure flinging the broken spring components across the garage embedding the spring or steel components into the garage walls cars or other items in the path of travel. Unfortunately sometimes people were in the path of travel of these explosive occurrences. As these springs failed as an attempted safeguard some manufacturers devised a "caging" system for the springs. These cages were retrofitted onto the stretched springs in an attempt to capture the parts that would release if a failure occurred. While these caging devices were helpful they were not completely effective. Some of these spring devices are still in use today. Whenever this condition exists or the quality of garage components are questionable a qualified professional service technician should be consulted.
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.
In most installations a warning tag is left attached adjacent to the torsion spring when the garage door is installed. This tag warns of the danger associated with the stored energy of this spring and alerts untrained individuals to not attempt any repair adjustment or to even touch the spring and associated hardware. When the label that should be attached to this spring becomes damaged is removed or tampered with it is important that a new warning label be reattached immediately to show the dangers of this spring tension
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.
