On August 15, 2002, a 14-year-old male farm worker (the victim) died after falling into an operating cattle feed grinder/mixer. The victim was using a handheld hay hook to drop hay bales into the operating grinder from the top of a stack of hay bales. He apparently lost his footing, slipped, and fell into the grinder. Approximately 20 minutes later, a coworker entered the area and noticed that the grinder was running unattended. He then called out to the victim and received no response. After looking into the mixing/grinding area of the machine he realized that the victim had fallen into the operating grinder and immediately stopped the machine. Emergency Medical Service (EMS) was summoned via 911 and responded within minutes. The coroner pronounced the victim dead on site. NIOSH investigators concluded that, to help prevent similar occurrences, employers should: 1) ensure that machinery such as top-loading feed grinders are positioned away from upper level work areas where employees could slip and fall into or onto it, and that the machinery is not operating during manual loading; 2) ensure that any keys which are required to operate equipment (tractor/power take off) are kept under the supervision and control of workers permitted to operate such machinery; 3) ensure compliance with child labor laws which restrict the type of work which youth less than 16 years of age are allowed to perform in agricultural settings; 4) ensure that constant supervision is provided when youth are present in a potentially hazardous working environment; 5) consider the use of a conveyor or other mechanical-type apparatus to elevate the feed (hay, corn silage, and alfalfa pellets) up to the loading point of the feed grinder; 6) develop, implement, and enforce a comprehensive safety program for all employees that includes, but is not limited to, training in hazard identification, avoidance, and abatement Additionally; 7) employers and equipment manufacturers should consider placing a warning sign or label on restricted agricultural equipment that indicates it is not to be operated by workers less than 16 years of age.
