The purpose of this study was to examine patients treated in an emergency department (ED) for injuries related to the use of log splitters. Data were obtained from the National Electronic Injury Surveillance System for the years 2011-2014. National estimates of ED visits for injuries associated with the use of log splitters were obtained, and descriptive epidemiological characteristics are presented. An estimated 37,000 ED visits for injuries related to the use of log splitters occurred during the study period. The majority of injuries occurred to the hand, with lacerations, fractures/avulsions, and amputations being the most common. The findings indicate that injuries from log splitters constitute a serious public health problem. Efforts to reduce injuries are discussed in accordance with the inherent challenges of detailing the circumstances surrounding these injuries.

Agriculture is recognized internationally as a hazardous industry. This article describes the trends and patterns of unintentional farm fatalities in Australia. Data from the National Coronial Information System were analyzed to assess all unintentional farm fatalities for the 2001-2015 period. A secondary comparison with earlier coronial system data from 1989-1992 was also completed to ascertain historical changes. There was no statistically significant change in the rate of work-related fatalities per 100,000 workers in the 2001-2015 period. However, there was a significant curvilinear reduction in all cases of fatality (work and non-work related) per 10,000 agricultural establishments, which decreased from 2001 to 2009-2011 and then increased to 2015. The longer-term data from 1989-2015 revealed a reduction of 30% in work-related cases per 100,000 workers and a reduction of 35% in all cases (work and non-work) per 10,000 agricultural establishments. For both work-related and all cases, there was a statistically significant reduction from 1989 to 2005 and then no change thereafter. The longer-term reduction in farm fatalities ceased in the mid-2000s, and the rate has remained stable since. Fatal injuries continue to impose a significant burden on Australian farming communities, with the rate remaining relatively static for the past ten years. New evidence-based interventions targeting priority areas are required to reduce the incidence of fatalities in Australia agriculture.

The pressure applied to the chest and back of a simulated grain entrapment victim was measured. Pressure sensors were attached to the chest and back of a manikin that was buried in grain in the vertical position. Measurements were made in four grain types at four grain depths ranging from the top of the manikin's shoulders to 0.61 m (24 in.) over the head. The pressure ranged from 1.6 to 4.0 kPa (0.23 to 0.57 psi). Based on available physiological information, this amount of pressure is unlikely to limit the respiration of an otherwise healthy adult male victim. However, other factors, such as the victim's age, gender, and body position in the grain, may influence respiration. The aspiration of grain appears to be the most likely asphyxiation risk during grain bin entrapment. Entering a grain storage bin is inherently dangerous, and Occupational Safety and Health Administration (OSHA) guidelines for permit-required confined spaces and grain handling facilities must be followed. Due to the risk of grain aspiration during engulfment, the development of safety equipment that could help protect the airway of a victim should be investigated.

This analysis featured a uniquely broad look at challenges and potentials for engaging agricultural and other industrial media more effectively in covering safety. It involved a content analysis of selected industry periodicals serving agriculture, mining, and transportation, which are three of the nation's most hazardous industries, in terms of human safety. Use of the social amplification of risk framework (SARF) provided insight on safety coverage. In particular, it tested previous research indicating that media coverage tends to amplify (increase) more than attenuate (decrease) a sense of risk. Analysis involved 18 periodicals (9 agriculture, 7 transportation, and 2 mining) spanning a five-year period from 2008 to 2012. Full-text digital analysis identified terms found in safety articles across all three industries. A manual review of articles revealed the quantity and nature of safety coverage within and among these industries. Results identified 528 safety-related articles published during the period. Transportation and mining periodicals averaged more than twice as many safety articles as the agricultural periodicals. The amount of coverage within the three industries also varied greatly. Findings on the nature of coverage supported previous media research within the SARF. Coverage across all three industries was clearly oriented more to amplifying than to attenuating risk. This study adds to the understanding of variations, commonalities, challenges, and potentials for enhancing safety coverage by media serving these three industries. It also provides direction for engaging industry media more effectively in the public safety mission. The authors recommend seven areas of opportunity for further research.

The burden of injury and death due to quad bike [all-terrain vehicle, or ATV] use cannot be allowed to continue unchecked, and ongoing delay in action may permit to further avoidable tragedies." -Royal Australasian College of Surgeons (2016, p. 13).

Dairy manure storages containing gypsum-based bedding have been linked anecdotally with injury and death due to presumed dangerous levels of gases released. Recycled gypsum products are used as a cost-effective bedding alternative to improve animal welfare and provide agronomic benefits to manure recycled back to the land. Sulfur contained in gypsum (calcium sulfate) can contribute to hydrogen sulfide (H2S) gas formation under the anaerobic storage conditions typical of dairy manure slurry. Disturbance of stored manure during agitation releases a burst of volatile gases. On-farm monitoring was conducted to document conditions during manure storage agitation relative to gas concentration and operator safety. One objective was to document operator exposure to H2S levels; therefore, each operator wore a personal gas monitor while performing tasks associated with manure storage agitation. Data from three dairy bedding management categories on ten farms were compared: (1) traditional organic bedding, (2) gypsum bedding, and (3) gypsum bedding plus a manure additive thought to reduce H2S formation and/or release. Portable meters placed around the perimeter of dairy manure storages recorded H2S concentrations prior to and during 19 agitation events. Results show that farms using gypsum bedding produced higher H2S concentrations during manure storage agitation than farms using traditional bedding. In most cases, gypsum-containing manure storages produced H2S levels above recognized safe thresholds for both livestock and humans. Farm operators were most at risk during activities in close proximity to the manure storage during agitation, and conditions 10 m away from the storage were above the 20 ppm H2S threshold on some farms using gypsum bedding. Although H2S concentrations rose to dangerous levels, only two of 18 operators were exposed to >50 ppm H2S during the first 60 min of manure storage agitation. Operators who are aware of the risk of high H2S concentrations near gypsum-laden manure storages can reduce their exposure risk by working upwind and away from the H2S plume within a closed tractor cab.

Recent interest in rearward visibility for private, construction, and commercial vehicles and documentation of rearward runovers involving bystanders outside the field of vision of the vehicle operator led to an investigation into the need for enhanced methods of rearward visibility for large, off-highway, agricultural equipment. A review of the literature found limited relevant research and minimal data on incidents involving rearward runovers of bystanders and co-workers. This article reviews the findings regarding the methods identified and tested to collect and analyze rearward visibility data, from the operator's perspective, for large self-propelled agricultural equipment, including the four-wheel drive tractors, combines, agricultural sprayers, and skid-steer loaders that are increasingly found on agricultural production sites. The methods identified, largely drawn from research conducted on private and commercial vehicles, were tested to determine their application in identifying rearward blind spots. These methods are described, and the findings from field-testing of specific machines are provided. Recommendations include establishing an appropriate engineering standard regarding rearward visibility of agricultural equipment with limited rearward vision and the use of rearward alarm systems for warning bystanders of rearward movement.

The purpose of this study was to determine regional differences within Utah in response to piloting a mobile respirator training and fit assessment program for pesticide applicators. The objectives were to describe worker perceptions of respirator use and training experiences. Pilot trainings were offered in two southern counties and two northern counties of Utah. A total of 141 individuals completed the post-training questionnaire regarding use and fit testing experience with respirators as well as perceptions of the benefits to protecting respiratory health. The majority of respondents were male (95.7%, f = 112). The proportion of participants in the southern counties who had respirator training experience (61.0%, f = 25) was not significantly higher (2 = 3.763, df = 1, p = 0.05) than the proportion of participants in the northern counties (43.0%, f = 43). Three-fourths (73.5%, f = 72) of participants in the northern counties agreed that they expect to wear a respirator in dusty conditions, while two-thirds (61.0%, f = 25) of participants in the southern counties agreed that they expect to wear a respirator in dusty conditions. The results indicated that more training should be done to improve perceptions and beliefs about using respirators. A high priority for this population will be identification of comfortable respirator options as well as communicating the importance of proper fit testing.

People with spinal cord injury/paraplegia are operating agricultural machinery despite the lack of research evidence to support seating interventions. These operators represent a vulnerable population in the agricultural workforce, and information to support their health in the workplace is urgently warranted. This research compared a group of subjects with paraplegia on different intervention cushion conditions during a simulated tractor driving task. Numerical data acquired from a pressure-mapping instrument were explored for statistical relationships within a small cohort of people with paraplegia participating in a feasibility study that was previously reported for clinical results. Relationships reaching statistical significance were found to support the primary hypothesis, while other hypotheses did not reach the threshold of significance. The primary hypothesis, that a contour tractor seat intervention condition would be inferior to other intervention conditions, was supported. For this cohort of heterogeneous users with paraplegia, a contour tractor seat of foam and cloth fabric manufacture was not an appropriate intervention selection versus other aftermarket wheelchair cushions.

Compared to their rural non-farming peers, farmers are less likely to access preventive healthcare services; however, the reasons for this disparity are poorly understood. We conducted semi-structured interviews with a total of 30 farm household members in central New York. Interview topics included farming identity, perceptions of one's health, past experiences with acute and preventive healthcare, and attitudes toward seeking healthcare services. Grounded Theory analysis of the interview transcripts revealed that (1) utilizing healthcare services is felt to be in conflict with the farming identity, (2) the need to conserve time and money for farm applications poses a barrier to healthcare utilization, (3) farmers decide to seek healthcare when they believe it is necessary to ensure survival of the farm, and (4) the decision to seek healthcare is most strongly driven by the presence of intolerable symptoms, prompting from others, and the perception that treatment will yield clear benefits. Efforts to increase farmers' utilization of healthcare services must address these considerations.
