Anti-tip brackets are devices designed to prevent freestanding cooking ranges from tipping. They are normally attached to a rear feet of the range, but can also be screwed into the wall behind the range. Furthermore, they are included in all range installation kits. A freestanding range that is not equipped with these devices, may tip over if enough weight is applied to its open door. A falling range can injure, scald, or burn anyone caught beneath.
According to the U.S. Consumer Product Safety Commission (CPSC), there were 143 incidents caused by range tip-overs from 1980 to 2006 and 33 of those incidents resulted in death. Imagine a small child standing on an open range door in order to see what is cooking on the stovetop and accidentally cause the entire unit to fall on top of them, along with whatever hot items may have been cooking on the stovetop. This is not just a hazard for children, but adults too have been injured by ranges tipping over.
In response to this danger, the American National Standards Institute (ANSI) and Underwriters Laboratories (UL) created standards in 1991 that require all ranges manufactured after that year to be capable of remaining stable while supporting 250 pounds of weight on their open doors. Manufacturers' instructions, too, require that anti-tip brackets provided be installed. Despite these warnings, retailer Sears estimated in 1999 that a mere 5% of the gas and electric units they sold were ever equipped with anti-tip brackets. As a result of Sears’ failure to comply with safety regulations, they were sued and subsequently required to secure ranges in nearly 4 million homes, a measure that has been speculated to have cost Sears as much as $500 million.
