Relevant Background on a Garage Door: "A garage door is a large door on a garage that opens either manually or by an electric motor (a garage door opener). Garage doors are frequently large enough to accommodate automobiles and other vehicles. Small garage doors may be made in a single panel that tilts up and back across the garage ceiling. Larger doors are usually made in several jointed panels that roll up on tracks across the garage ceiling, or into a roll above the doorway. The operating mechanism is spring-loaded or counterbalanced to offset the weight of the door and reduce human or motor effort required to operate the door. Less commonly, some garage doors slide or swing horizontally. Doors are made of wood, metal, or fiberglass, and may be insulated to prevent heat loss. Warehouses, bus garages and locomotive sheds have larger versions..." A typical version of an overhead garage door used in the past would have been built as a one-piece panel.[1] The panel was mounted on each side with unequal parallelogram style hinge lifting mechanism. Newer versions of overhead garage doors are now generally built from several panels hinged together that roll along a system of tracks guided by rollers.[1] The weight of the door may be 400 lb (180 kg) or more, but is balanced by either a torsion spring system or a pair of extension springs.[2] A remote controlled motorized mechanism for opening garage doors adds convenience, safety, and security....In situations involving residential attached garages where the insulating value and the energy efficiency of a garage door is important to prevent overheating and freezing problems, as well as for comfort and energy savings...An extension spring counterbalance system consists of a pair of stretched springs running parallel to the horizontal tracks. The springs lift the door through a system of pulleys and counterbalance cables running from the bottom corner brackets through the pulleys. When the door is raised, the springs contract, thus lifting the door as the tension is released. Typically these springs are made of 11 gauge (3 mm) galvanized steel, and the lengths of these springs are based on the height of the garage door in question. Their lifting weight capacity can best be identified by the color that is painted on the ends of the springs...Maintenance of garage door is described in the manufacturer's instructions and consists of periodic checks for correct operation, visual inspection of parts, and lubrication...Garage doors cause injury and property damage (including expensive damage to the door itself) in several different ways. The most common causes of injury from garage door systems include falling doors, pinch points, improperly adjusted opener force settings and safety eyes, attempts at do-it-yourself repair without the proper knowledge or tools, and uncontrolled release of spring tension (on torsion spring systems)...A garage door with a broken spring, or the wrong strength spring, can fall. Because the effective mass of the door increases as the garage door sections transfer from the horizontal to vertical door tracks, a falling garage door accelerates rapidly. A free falling garage door can cause serious injury or death...The sections and rollers on garage doors represent a major pinch hazard. Children should never be allowed near a moving garage door for this reason. On manually operated garage doors, handles should be installed vertically, to promote "vertical orientation of the hand"...Mechanical garage door openers can pull or push a garage door with enough force to injure or kill people and pets if they become trapped. All modern openers are equipped with “force settings” that make the door reverse if it encounters too much resistance while closing or opening. Any garage door opener sold in the United States after 1992 requires safety eyes—sensors that prevent the door from closing if obstructed. Force settings should cause a door to stop or reverse on encountering more than approximately 20 lbs (9.07 kg) of resistance. Safety eyes should be installed a maximum of six inches above the ground. Many garage door injuries, and nearly all garage door related property damage, can be avoided by following these precautions...Certain parts, especially springs, cables, bottom brackets, and spring anchor plates, are under extreme tension. Injuries can occur if parts under tension are removed....Extension spring systems should always be restrained by a safety cable that runs through the middle of the spring, tying off to a solid point at the rear and front of the horizontal door track. The safety cable prevents hazards to bystanders when a spring, pulley, or cable breaks under tension and makes the system quite safe...Torsion spring systems can be very dangerous as they are always under tension and release energy when the spring fails. Serious injury or death can be caused by the projectile pieces of a failed torsion spring. Many people have been injured or killed trying to adjust torsion springs, and special training and procedures are required to safely adjust a torsion spring, it is a job for a professional not a homeowner or DIYer...

Most retail stores have some form of automatic doors, whether they are sliding doors, revolving doors, swinging doors, or folding doors.
