Due to its weight, hay can cause a number of injuries to humans, particularly those related to lifting and moving bales, as well as risks related to stacking and storing. Hazards include the danger of having a poorly constructed stack collapse, causing either falls to people on the stack or injuries to people on the ground who are struck by falling bales. Large round hay bales present a particular danger to those who handle them, because they can weigh over {{convert|1000|lb}} and cannot be moved without special equipment. Nonetheless, because they are cylindrical in shape, and thus can roll easily, it is not uncommon for them to fall from stacks or roll off the equipment used to handle them.  From 1992 to 1998, 74 farm workers in the [[United States]] were killed in large round hay bale accidents, usually when bales were being moved from one location to another, such as when feeding animals.<ref name="danger">{{cite journal|journal=The National Institute for Occupational Safety and Health|url=https://www.cdc.gov/niosh/docs/2001-146/|title=Hazards Associated with Using Farm Tractors to Move Large Bales|year=2001|doi=10.26616/NIOSHPUB2001146|access-date=September 10, 2004}}</ref><ref name="Minnesota">{{cite journal|url=http://jama.ama-assn.org/cgi/content/full/279/9/647|title= Fatalities Associated With Large Round Hay Bales—Minnesota, 1994-1996|journal=JAMA|date=4 March 1998|volume=279|issue=9|pages=647–649|doi=10.1001/jama.279.9.647-JWR0304-2-1|access-date=September 10, 2004}}</ref>
