A 15-year-old male farm worker (the victim) died after the tractor he was operating overturned into a manure pit. The tractor was equipped with a manure scraper fashioned from half a tractor tire mounted on the draw bar at the rear of the tractor. The victim and another 15-year-old-male, who was sitting on the tractor's left fender, were scraping cattle manure across a concrete-surfaced barnyard toward the mouth of the manure pit. As the tractor approached the open mouth of the manure pit, the victim applied the brakes, and the tractor skidded on the concrete surface wet from the manure. The left front wheel slid over the concrete edge of the manure pit, causing the tractor to overturn into the manure pit. The tractor came to rest upside down, pinning the victim underneath. The victim and the tractor were completely submerged in the manure pit. The passenger was able to reach the dirt side wall of the pit, climb out, and run for help. Other farm workers immediately called 911 and went to assist the victim. The local Fire Department and rescue personnel arrived within minutes and started to search for the victim. Approximately 35 minutes after the incident, the victim was extracted from the manure pit. Rescue personnel initiated CPR immediately and transported the victim to a local hospital where he was pronounced dead on arrival. NIOSH investigators concluded that to help prevent similar occurrences, employers in agricultural operations should: 1) ensure that manure pits are marked as hazardous areas and are substantially barricaded, as determined by the design of the pit, to prevent inadvertent entrance; 2) consider seeking the assistance of their local county extension agent, an agricultural engineer, or equipment dealers or manufacturers to ensure that attachments for machinery fabricated on the farm do not compromise safe operation of the machine; 3) ensure compliance with all Department of Labor Child Labor Laws, rules and regulations regarding employment of youths in agriculture; 4) assess the tasks assigned to youths and ensure that youths are properly trained to perform these tasks; 5) ensure that passengers are prohibited from riding on tractors, additionally; 6) parents should discuss the types of work their children are performing and become familiar with the occupations and conditions of work that are prohibited for minors.
