When people think of household hazards they often overlook the largest one. Garage doors, particularly older models, can be very dangerous. Your garage door should provide many years of trouble free service if it is installed, maintained, and operated properly. Here are some useful safety tips. NOTE: This is not intended to be a comprehensive list of every safety precaution, always consult your manufacturer's user guide for safety information about your specific door model. A garage door, sometimes weighing up to 600 pounds, is the largest moving object in your home and is often operated by an electric door opener. Proper installation, maintenance, and testing are necessary to keep the garage door working safely. An opener that is not installed properly could result in a serious and in some cases fatal injury. Print these tips and review them with every member of your family. Education is the best defense for preventing accidents.
