Garage door safety

The garage door is the largest moving object in a home. An improperly adjusted garage door opener can exert strong and deadly forces and might not reverse the garage door in an emergency. The garage door counterbalance springs should be properly adjusted in order for the safety reverse system to function properly. Thus, proper installation and maintenance are extremely important in order for the garage door and garage door opener to operate smoothly and safely.
The header bracket, which attaches the front end of the opener track to the header wall, must be securely attached to the structural members of the garage wall. If not, the opener might not reverse the garage door in an emergency. The rail can also pull away from the wall.
All garage door openers manufactured and installed in the United States since 1982 are required to provide a quick-release mechanism on the trolley that allows for the garage door to be disconnected from the garage door opener in the event of entrapment. The quick-release handle should be mounted no higher than six feet from the ground. Homeowners should be familiar with this mechanism, because garage door springs can relax over time, and pulling the release could lead to a free-falling door.Garage door openers manufactured since 1982 are also required to reverse the garage door if it strikes a solid object.
The wall console/push button should be mounted at least five feet from the floor and the remote controls should be kept out of the hands of children. Children should never be allowed to play with or use the garage door opener remotes or wall pushbuttons. Homeowners should also keep a moving door in sight until it fully opens or closes.
Under U.S. federal law (UL 325), garage door openers manufactured for the U.S. since 1993 must include a safety reversing system, such as photoelectric eyes mounted no higher than six inches above the ground, with a light beam spanning the door opening. The garage door opener is required to reverse the door to the open position if the beam is broken. Other examples of safety reversing systems, allowed within the guideline of UL 325, include electric safety edges, which reverse with approximately 15 pounds of downward pressure, and a garage door and opener system without photo eyes, tested together, which reverses upon approximately 15 pounds of pressure.
