Hence, it is important to determine which warning method is best suited to draw the attention of a remote supervisor of an autonomous machine in an emergency. To achieve this objective, participants were recruited and asked to interact with a simulation of an autonomous sprayer. Seven warning methods (presented alone or in combinations of visual, auditory, and tactile sensory cues) and four remote supervision scenarios (in-field, close-to-field, farm office, outside the farmland) were considered in this study.

While there has been ongoing surveillance of mortality and morbidity involving agricultural confined space-related incidents, such as grain storage facilities, few resources have been invested in estimating the frequency of livestock waste-related incidents, which are often reported as primarily involving confined spaces. Existing surveillance efforts have historically underreported fatal cases, injuries, and near misses and misclassified these incidents as non-farm related. For nearly 40 years, the Purdue Agricultural Confined Spaces Incident Database (PACSID) has been used to document agricultural confined space-related incidents, of which manure storage and handling activities have accounted for 22% of the cases documented. The specific goal of this study was to address the gap in the current understanding of the frequency and severity of injuries associated with livestock waste storage, handling, and transport by: (1) developing a consistent way to identify, document, and code these cases; (2) summarizing all known U.S. cases, both fatal and non-fatal, currently documented in the PACSID; (3) identifying the most significant risks contributing to livestock waste storage, handling, and transport-related incidents; and (4) providing evidence-based recommendations and mitigation strategies to enhance the effectiveness of current injury prevention measures. The PACSID and other sources were mined for relevant data, and an aggressive effort was made to document additional cases through a variety of surveillance methods. A total of 459 individual U.S. cases from the study period (1975 to 2019) were identified, coded using a uniform coding system, and summarized. Overall, cases were documented in 43 states, with 66% (302 cases) documented in heavily agricultural and, more specifically, historically strong dairy production states. Of the cases reviewed, 59% were fatal, males ages 21 to 30 and dairy farm workers were identified as high-risk populations, 20% were identified as under the age of 21, and 49 incidents involved multiple victims.

These events often lead to severe injury and permanent disability but can be prevented with proper use of PTO shielding. A promising strategy for increasing PTO shielding on farms has been the introduction of user-friendly shielding options by qualified safety specialists. This study looks at the cost-effectiveness of this approach. The cost-effectiveness of this PTO shielding strategy was calculated based on program-related costs, the PTO shield cost, the lifespan of PTO shields, and the number of PTO shields needed to prevent an entanglement. The cost per entanglement prevented was then calculated by dividing the total costs by the number of entanglements prevented in several cost-estimate scenarios. Costs were adjusted for inflation to 2019 dollars. Costs per entanglement prevented ranged from a low of $921,544 (assuming a 10-year PTO lifespan and using 12,487 as the number needed to treat, i.e., to prevent a PTO entanglement, referred to as the NNT) to a high of $18,583,492 (assuming a three-year PTO lifespan and 67,119 as the NNT). The cost per entanglement prevented at the median PTO lifespan of five years and median NNT of 39,802 was $6,612,244. Based on our estimates, the cost-efficacy of increasing PTO shielding using qualified safety specialists differs widely based on the shield lifespan and the number of shields needed to avoid one entanglement. However, if the cost of introducing PTO shields in on-farm visits is coupled with other on-farm services that defray these costs, then the cost-efficacy increases considerably.</p>","PeriodicalId":45344,"journal":{"name":"Journal of Agricultural Safety and Health","volume":" ","pages":"205-214"},"PeriodicalIF":1.0,"publicationDate":"2021-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39585914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Operator protection devices and crash notification systems can protect the operator in ATV rollover incidents. ABSTRACT. All-terrain vehicles (ATVs) are the second most common source of injury, following tractors, in U.S. agriculture. Rollovers are the leading cause of death in farm ATV incidents, constituting about 85% of ATV-related deaths. There is neither a significant practical solution for ATV rollover crashes in the U.S. nor standards and rules for implementing such a solution. Behavior-based control methods have been used for several decades but have reached their limit of success. Hence, engineering controls are needed to significantly decrease the severity of injuries in ATV rollover incidents (as in tractor incidents). In this study, engineering technologies to protect the operator in agricultural ATV crashes were reviewed. The discussion includes improving crash testing and stability ratings, evaluating static stability of ATVs, dynamic handling tests of ATVs, using automatic systems to notify first responders of a crash, and testing and applying operator protection devices.

This study examined the association between age and driving performance among FEOs using a simulated driving environment. We demonstrated that older FEOs have longer perception response times when encountering an incurring semi-truck during a simulated drive than younger FEOs. These results persisted when adjusted for selected medical diagnoses and medications, tractor generation, and tractor horsepower.
