Factors that Influence Farm Safety Decisions of Young Adults when Entering Agricultural Grain Bins

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.

Reserved Abundance:

Preindustrial public and state granaries were utilitarian buildings, but they were also instruments of food security regimes, representing a government's promise of abundance for its people. In the early modern period such granaries became widespread across Asia, Europe, and European colonies, ranging from territorial storehouse networks to monumental civic buildings near city centers. In Reserved Abundance: State Granaries of Early Modern Istanbul, Namık Erkal discusses Ottoman Istanbul's state granaries, using primary textual and visual sources to trace the type's evolution from modified, repurposed buildings (e.g., shipsheds and bathhouses) to purpose-built storehouses. He also evaluates the forms and importance of storage systems such as encased single-layer and double-stacked wooden grain bins. Erkal defines the capacities, dimensions, and variations of Istanbul's granaries, maps their locations in relation to major urban functions and locales, and compares them with similar buildings within and outside Ottoman domains.

Evaluation of Wireless Phosphine Sensors for Monitoring Fumigation Gas in Wheat Stored in Farm Bins

Fumigation of grain bins with phosphine tablets is one method of insect control for stored products. Monitoring the concentration of the toxic gas at many locations over several days for a given structure or container can be challenging. In this study, a commercially-available system that wirelessly measures phosphine was evaluated in small-scale and large-scale tests. Small-scale testing was performed to study the repeatability and accuracy of the sensors. The wireless sensors were within 30 ppm of each other, over a range of 700 ppm phosphine. Large-scale testing evaluated the system during the fumigation of wheat stored in 7 m diameter, 120 metric ton, steel grain bins. As a reference, monitoring lines were distributed at several positions and depths in the bin in order to sample phosphine gas concentrations. A series of three fumigation trials were performed, with each lasting for over six days. The wireless devices collected local phosphine concentrations and temperatures every two hours without assistance from personnel. Although the fumigation trials were significantly different in terms of patterns in gas concentration over time, the two sampling methods gave similar trendlines. However, the automated data provided a more detailed picture of the fumigation process. This information may help fumigation managers to better evaluate fumigations and assure successful insect control.

Utilization and Effectiveness of Harnesses and Lifelines in Grain Entrapment Incidents: Preliminary Analysis

No previous studies have been found that document the level of use or validate the effectiveness of safety harnesses and lifelines in the prevention of or extrication from grain entrapments or engulfments. This article addresses that void via analysis of the data contained in the Purdue Agricultural Confined Space Incident Database. A total of 1,147 cases involving entrapments or engulfments in grain masses were mined for terms that might indicate the use of a safety harness, lifeline, fall restraint system, rope, or outside observer. Case information ranged from brief news accounts to comprehensive investigation results. The review turned up 38 incidents (<5%) in which these safety devices were identified as having been used by either workers or rescuers during access to a storage structure. In 26 of the 38 cases (68%) where safety devices were identified, the entrapment or engulfment resulted in a fatality. The two most common reasons cited for failure of these devices were (1) that the lifeline or rope was too long (17 incidents) and (2) that the worker had removed the harness with the attached lifeline while in the structure (6 incidents). It was also determined that these devices, if used improperly, can lead to secondary injuries of the victim. The preliminary evidence suggests that use of these devices alone does not ensure the user’s safety and may even provide a false sense of security if used without proper training. It was further found that an approved body harness and safety line provided little or no protection from either entrapment or falls if used in the presence of vertically crusted grain surfaces, without proper anchors, or not in conjunction with outside observers. The presented results are important for safety professionals to consider as they endeavor to reduce the risk of grain entrapment and engulfment incidents through training, education, selection of personal protective equipment, etc., and should contribute to the development of new structural standards for grain bins. It is the intent of this article to elucidate the importance of training and proper use of these safety devices.

The Middens at Tora Nju and Their Adjacent Stone Enclosure

Tora Nju is the local name for a collapsed stone walled enclosure situated approximately 20km from Sowa Spit, 200 m south of the Mosetse River, and 7 km east of the present strandline of Sowa Pan. The site that takes its name from this ruin includes several midden areas containing pottery, stone tools, and faunal remains along with house structures and grain bins. Excavations were carried out in parts of all these site components. The middens contained a moderately rich suite of materials including sherds, glass and shell beads, metal, and animal bones. The enclosure, however, yielded very little. Consequently, we concentrate here first on the middens before turning to the enclosure. Typical Khami vessel forms predominate throughout the midden stratigraphy; a few midden sherds are comparable with Lose wares in part contemporary with Khami ceramics. A possible earlier Leopard’s Kopje presence is also indicated. Glass beads characteristic of Khami Indo-Pacific series were also recovered from all midden levels. Three charcoal samples yielded contradictory radiocarbon dates for the middens, and we have no direct means for dating the enclosure. We evaluate evidence for a takeover of Sowa salt production by the Khami state sometime in the early 15th century. Finally, we examine historical records and incorporate current linguistic and dna studies of Khoisan and Bantu speakers to illuminate the social history of the Tora Nju region.
