Highlights: This article describes a cost assessment of a PTO driveline shielding intervention. Considerations for effective occupational safety interventions beyond reductions in injuries or fatalities are described. The financial viability of combining various on-farm services to reduce intervention costs is discussed.

Abstract: PTO entanglements are a primary injury concern on U.S. farms, affecting adults and children. 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.

HIGHLIGHTS Rollovers are the leading cause of injury and fatality in farm all-terrain vehicle (ATV) incidents. Engineering technologies to prevent rollovers or protect the operator in ATV crashes were reviewed in this study. The advances in safety for ATVs are correlated with improvements in stability, handling, and crashworthiness. 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. The available standards, rules, and recommendations related to these technologies around the world are also discussed.

HIGHLIGHTS We identified 48 fatal and 187 non-fatal agricultural injuries in Florida from 2015-2019. Vehicles and environmental sources were the two leading injury sources. Using multiple data sources helped us understand the at-risk populations. ABSTRACT. The purpose of this study was to examine and describe fatal and non-fatal agricultural injuries documented in Florida. We used Occupational Safety and Health Administration (OSHA) data and AgInjuryNews.org (AIN) data from 2015 through 2019 to identify 48 fatal and 187 non-fatal injuries during the five-year study period, with 86% (40 fatal, 175 non-fatal) of these injuries being occupational. A total of 101 (43%) people were injured as a result of transportation incidents. Major injury sources were vehicles (46%) and environmental sources (heat, lightning, etc.) (14%). Using AIN data, we identified risks for youth under the age of 18 and for individuals age 65 and older. This study suggests the need for additional injury surveillance efforts to gather demographic information to identify at-risk populations.

HIGHLIGHTS This study uses a new tractor driving simulator to examine the impact of age on perception response time in an emergency braking situation. The results demonstrate increased risk for crash among older farm equipment operators. ABSTRACT. Transportation-related incidents are the leading cause of occupational fatalities for all industries in the U.S. In the agriculture industry, where tractor-related incidents are the leading cause of occupational fatality, fatal crashes occur more frequently among senior farm equipment operators (FEOs) than younger FEOs. 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. However, due to the small sample size and limitations of the tractor driving simulator, its use for event perception response time research is questionable. The tractor driving simulator used in this study may be better suited for distracted driving studies and studies comparing the ways in which FEOs drive passenger vehicles compared to tractors.

HIGHLIGHTS A grain handling scenario-based survey was administered to college students studying agriculture. Participants chose an action after reading each scenario and ranked factors affecting their decision-making. Most participants chose a "safe" option and claimed to value their personal safety when making decisions. Parental authority and pressure had little influence on participants' decisions to enter grain bins. ABSTRACT. The approaches that parents take in the supervision of youth who perform hazardous tasks on family farms can affect youth safety outcomes. This research examines the most significant factors affecting youths' decisions to enter agricultural grain storage facilities. Over 200 students attending a Midwestern land-grant university who had grain bin experience as youth completed a decision-making survey. Students chose from a list of actions in three realistic but hypothetical scenarios involving grain bin entry. Afterward, they ranked factors according to the level of importance in their decision. Although most participants chose options that emphasized safety when answering the scenario questions and held the "personal safety" factor in highest regard, some chose higher-risk options and valued "productivity." The findings revealed that youth held little value in their parents' authority and pressure when making decisions related to grain bin entry. The study's limitations are addressed, as are the implications of these findings for youth safety outcomes on family farms.

HIGHLIGHTS The total number of injuries to all youth on farms consistently declined during the 14-year period from 2001 to 2014. Injuries to household farm youth, after initial declines, increased in 2012 and 2014. Although progress in farm youth safety has been made, farms continue to be hazardous places for youth. ABSTRACT. The National Institute for Occupational Safety and Health (NIOSH) conducted injury surveillance for youth on U.S. farms for two decades to measure childhood injury burden, track injury trends, and monitor hazardous injury exposures. The Childhood Agricultural Injury Survey (CAIS), a regionally stratified telephone survey, collected injury and demographic data for all youth less than 20 years of age on U.S. farms. Results from the 2014 survey are provided. Trend analyses for all survey years were conducted using a Poisson regression model with generalized estimating equations. Rate ratios with corresponding 95% confidence intervals were calculated from the model. In 2014, there were an estimated 11,942 youth farm injuries. Of these, 63% occurred to household youth. Youth between the ages of 10 and 15 incurred the most injuries, and 34% of the injuries were work-related. The total number of injuries to all youth on farms consistently declined during the 14-year period from 2001 to 2014, with annual injury rates ranging from 13.5 to 5.7 per 1,000 farms. The injury rates for household youth decreased through 2009 but increased slightly in 2012 and 2014. Farms continue to be hazardous environments for youth. Although there has been a significant decrease in the overall numbers and rates of youth farm injuries over the past decades, researchers should continue to monitor areas that remain a concern. One area that is specifically troublesome is the increase in injury rates observed for household youth in 2014.

HIGHLIGHTS The actuating force, torque, and application rate needed to operate the control levers of a walk-behind type paddy transplanter were determined. The results will be beneficial for the development of a remote-control or autonomous system for the transplanter. Such a system will reduce operator fatigue, resulting in increased work efficiency and safety. ABSTRACT. An enormous amount of human fatigue is involved in operating the walk-behind type paddy transplanters widely used in South Asian countries, especially India. To operate a transplanter remotely, accurate estimation of the actuating force needed to operate the control levers (push/pull type), the stroke length of the levers, and the frequency of use of the levers is required so that the mechanical levers can be replaced with appropriate electronic sensors, control units, and actuators. In this study, the actuating forces and required torques of the control levers of a walk-behind type paddy transplanter (Kubota NSP-4W, model MZ175-B-1) were measured using three load-measuring instruments. The results revealed that about 24.1 N of force was required to control the accelerator lever, while the left and right steering levers required an actuating force of 24.0 N each. To start the transplanting mechanism, a much higher actuating force (78.1 N) and torque (15.47 N-m) were required 54 times per hour for the planting clutch lever; however, to stop the mechanism, a comparatively smaller force (28.3 N) and torque (5.71 N-m) were required 54 times per hour. Movement of the transplanter was controlled with the shift clutch lever, which required 14.30 N of force and 2.72 N-m torque for forward movement of the transplanter in field conditions, while 12.7 N of force and 2.88 N-m torque were required for forward movement of the transplanter on paved roads. These findings will be beneficial for selecting the force and stroke length of actuators for the development of a remote-control or autonomous system for walk-behind type paddy transplanters and similar machines, which is expected to substantially reduce the operator workload and enhance both workability and safety.

HIGHLIGHTS The farming population is at risk of injury due to sleep deprivation. Loss of sleep during previous night affects balance performance in farmers. Objective measures of sleep are more reliable than subjective measures for predicting balance performance. ABSTRACT. This study aimed to investigate the ability of both subjective and objective sleep measures to predict balance difficulty in agricultural workers. Seven male farmers from rural Nebraska were analyzed for static balance performance following a bout of sleep. Actiwatches were used to measure objective sleep hours and subjective questionnaires, including the Epworth Sleepiness Scale and the Pittsburgh Sleep Quality Index, were used to measure subjective hours of sleep and sleep quality. The participants were observed for 12 sessions, with six in planting season and six in harvest season. Static balance testing consisted of measuring the area, total displacement, and maximum range in the anteroposterior and mediolateral directions of the individual's center of pressure with Tekscan pressure mats. Overall, it was found that objective measures had a higher correlation with the magnitude of balance deviations than subjective measures.

HIGHLIGHTS A total of 133 cases were documented in a seven-state region, with Iowa reporting 43% of the cases and asphyxiations accounting for 42% of all cases. Most victims were male (>79%) with an average age of 38 years. The overall fatality rate was 57%, and 16% of the victims were under the age of 21. Thirteen incidents involved secondary victims, including eleven incidents involving two, one incident involving three, and one incident involving four. ABSTRACT. Research was conducted to document, classify, analyze, and summarize available injury and fatality data involving facilities and equipment for livestock manure storage, handling, and transport in the seven-state region (Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, and South Dakota) served by the Central States Center for Agricultural Safety and Health (CS-CASH). Data were initially drawn from the Purdue Agricultural Confined Space Incident Database (PACSID), which contained over 2,400 individual U.S. cases of agricultural confined space related entrapment, engulfment, entanglement, asphyxiation, and falls that were documented between 1975 and 2019. Data from these cases have been partially summarized and published, but the findings did not include in-depth analysis of manure-related incidents. Approximately one in five (460) of the 2,400+ cases that were documented over 44 years involved storage, handling, or transport of livestock wastes, including exposure to toxic gases. Of these, 133 cases were documented as having occurred in the targeted seven-state region. Each case was identified and coded according to a protocol developed previously to classify incidents related to livestock manure handling, storage, and transport. Iowa and Minnesota accounted for 79% of the total, with swine operations accounting for 33% of cases when livestock type was known. Of the victims, 79% were male. Ages ranged from 1 to 85, with an average age of 38, and 15% of the victims were age 21 and under. There were 13 incidents for which two or more victims were identified, including one incident involving four victims. It is believed that historical under-reporting of incidents, especially non-fatal incidents, continues to be a barrier to achieving a more comprehensive understanding of the scope and magnitude of the problem. However, the findings are sufficient to be used in cooperation with stakeholders to enhance the content and delivery of evidence-based agricultural safety and health programs, promote safer work practices, and contribute to the development of engineering design standards. The desired outcomes of this research include more effective strategies to protect farmers and farm workers who are at high risk of manure-related injuries. The findings also provide a sufficient baseline to gauge the effectiveness of future injury prevention measures.

HIGHLIGHTS Demonstrations and one-on-one training were the most preferred learning methods. The most-used learning methods were electronic methods. Printed materials were preferred and perceived as effective by Baby Boomers. ABSTRACT. The purpose of this study was to investigate differences among generational cohorts in the agricultural workforce in learning methods, including frequency of use, perceived effectiveness, and preference. A total of 211 participants representing the agricultural workforce completed either a paper-based or online questionnaire. Generational cohorts were determined using participants' birth years. The results show that regardless of the generational cohort, demonstrations and one-on-one training were the most preferred learning methods and were also perceived as the most effective methods. Participants indicated that they mostly use electronic methods to learn about agricultural safety and health. Generational differences were found for some learning methods. Printed materials were found to be preferred and perceived as effective by Baby Boomers more so than the other cohorts. Electronic methods were mostly used by Gen X and Millennial participants. For learning about agricultural safety, demonstrations are the most preferred and most effective methods but are not used as frequently as the other learning methods. Agricultural safety education should continue delivering safety demonstrations.
