In the upper right is a smaller cross-section of a<unk>  storage bin with a figure trapped beneath the<unk> . At the bottom is text saying "Illustration of<unk>  engulfment hazard."<unk> , or<unk>  engulfment, occurs when a person becomes submerged in<unk>  and cannot get out without assistance. It most frequently occurs in<unk>  bins and other storage facilities such as silos or<unk>  elevators, or in<unk>  transportation vehicles, but has also been known to occur around any large quantity of<unk> , even freestanding piles outdoors. Usually, unstable<unk>  collapses suddenly, wholly or partially burying workers who may be within it.<unk>  occurs when victims are partially submerged but cannot remove themselves; engulfment occurs when they are completely buried within the<unk> . Engulfment has a very high fatality rate. While the death rate from workplace accidents on American farms has declined in the first decades of the 21st century,<unk>  deaths have not, reaching an all-time annual high of 31 deaths in 2010. Many of those victims have been minors. Agricultural organizations have worked to protect them and improve rescue techniques, as well as spread awareness among farmers of prevention methods. Primary among these is a federal regulation that forbids opening an auger or other opening at the bottom of a<unk>  storage facility while someone is known to be "walking down the<unk> " within. Smaller family farms, however, are exempt from most federal labor regulation specific to agriculture, and no safety regulations govern children working for their parents. In 2011, the U.S. Department of Labor proposed sweeping new regulations that would have changed this, prohibiting underage workers from entering silos, among other provisions. They were withdrawn after protests from farmers and politicians of both U.S. parties.
