Final answer:
It is false that an automatic garage door does not require a safety feature to prevent it from closing on an object. Garage doors must include sensors for safety due to regulations.
Step-by-step explanation:
The statement that it is not required to have a safety feature that automatically raises and keeps a garage door up if it hits something on the way down is false. The Consumer Product Safety Commission (CPSC) requires that all automatic garage door openers manufactured or imported after January 1, 1993, for sale in the United States must have an external entrapment protection system.
This system usually includes sensors that detect when an object is in the path of the closing door and automatically reverse its direction to prevent injury or damage to property.
It's important to note that safety features, including mechanisms that prevent a garage door from closing on an obstruction and automatically raise it if an obstacle is detected, are designed to enhance safety. While it may not be a legal requirement in all areas, having such safety features is generally considered a best practice.
The automatic reversal feature, often implemented using photoelectric sensors or pressure-sensitive edges, helps prevent accidents and injuries. Without this feature, a closing garage door could pose a risk to people, pets, or objects in its path. Accidents involving garage doors can result in serious injuries or property damage.
Many garage door openers come with built-in safety features to comply with industry standards and regulations. Even if it's not a legal requirement in your specific location, it's advisable to prioritize safety and consider having such features installed to protect yourself, your family, and your property. Always follow the manufacturer's recommendations for maintaining and testing these safety features regularly to ensure they are functioning correctly.
