“…The study results from one chainsaw model, which had the similar tool characteristics but was lighter compared to the chainsaw in the current study -2.2±0.5 m/s 2 on the front handle and 2.0±0.8 m/s 2 on the rear handle, were somewhat lower than the findings on the gloved hand, 3.1±0.7 m/s 2 on the left hand and 3.3±0.5 m/s 2 on the right hand in the current study. Calvo et al examined the vibration of multiple agricultural backpack blowers with 2.9-3.6 kW engine power, weighing 11-12 kg at 6,160-7,000 rpm; the mean acceleration value measured at the control handle was 1.7±0.5 m/s 2 -similar to results obtained in the current study -1.6±0.4m/s 2 [14].…”

Introduction and Objective. About 2.5 million workers in the USA are exposed to hand-arm vibration (HAV) from power tools. The aims of the study were to evaluate occupational exposure to HAV during grounds maintenance equipment operations and the effect of general work gloves on vibration magnitude under controlled laboratory conditions. Materials and method. A simulation of grass trimmer, backpack blower, and chainsaw operations was conducted by two participants to measure vibration total value (a hv ) using vibration dosimeters wearing gloves. a hv was also measured on the bare hands during grass trimmer and backpack blower operations. Results. a hv of the gloved hand was 3.5-5.8, 1.1-2.0, and 3.0-3.6 m/s 2 during the grass trimmer, backpack blower, and chainsaw operations, respectively. a hv of the bare hand was 4.5-7.2 and 1.2-2.3 m/s 2 for the grass trimmer and blower operations, respectively. Conclusion. The highest HAV exposure was observed during the grass trimmer operation which showed higher vibration attenuation of the gloves.

“…1.1.3 | Health and safety Although there is very little information on health and safety aspects specifically for the cultivation of miscanthus, the literature provides a general overview of on-farm health and safety. Health risks in agriculture have been related to accidents involving heavy machinery (Fargnoli et al, 2018), exposure to vibration, noise (Calvo et al, 2019) and dust (Rumchev et al, 2019), transmission of diseases from animals to humans (Mori & Roest, 2018), musculoskeletal disorders (Kumaraveloo & Lunner Kolstrup, 2018), and exposure to pesticides (Kim et al, 2017) and fertilizers (Ahmed et al, 2017;Hill et al, 2019), among others.…”

Social assessment of miscanthus cultivation in Croatia: Assessing farmers' preferences and willingness to cultivate the crop

et al. 2023

View full text Add to dashboard Cite

Social aspects of miscanthus cultivation have been investigated in a limited way in the scientific literature. Adopting existing frameworks for social life-cycle assessment enables assessments to include numerous social aspects; however, the relevance of these aspects depends on the local context. This study aims to identify the most relevant social aspects from the farmers' perspective using a previously proposed framework for the assessment of the stakeholder 'farmer'. It is based on a case study for miscanthus production in Sisak Moslavina in Croatia. The existence of abandoned lands in Croatia presents an opportunity for the cultivation of miscanthus as a potential source of biomass for the production of bio-based materials and fuels. The study seeks to assess the feasibility of cultivating miscanthus in the region, taking into account potential challenges and opportunities, as well as farmers' willingness to adopt the crop, and to understand the reasons behind land abandonment. We conducted a survey among 44 farmers in the region and used a scoring method to identify the most relevant social aspects. The aspects most valued by the farmers were health and safety, access to water, land consolidation and rights, income and local employment, and food security. Responses to the question of whether they would adopt the crop highlight the importance of an established market, good trading conditions and profitability of cultivation. The survey also enabled an understanding of farmers' preferences with respect to the production conditions of crops. The farmers regarded the provision of subsidies as one of the main factors that render a crop attractive. Opportunities for the adoption of the miscanthus cultivation include high yields and low input requirements. Barriers include land conflicts and land availability. Despite the opportunities for miscanthus development in the region, there are important challenges to consider for successful implementation of the crop.

“…However, there are no standardized methods for HAV exposure assessment. Many studies traditionally have measured acceleration values directly from tools by mounting an accelerometer on the tool handle 2–6 while more recent studies have measured vibration magnitude at the hand‐handle interface using hand‐held/hand‐mounted adapters in which an accelerometer is attached to or inserted 7,8 . Most recently, vibration dosimeters integrated with hand adapters 9,10 are available which enable to obtain daily exposure dose while minimizing interference with job activities.…”

Long-term, excessive exposure to hand-arm vibration (HAV) through vibrating hand tools can induce hand-arm vibration syndrome (HAVS) which is a complex of peripheral vascular, neurological, and musculoskeletal disorders. 1 The development of HAVS depends on a variety of factors such as vibration magnitude, frequency, direction, exposure duration, posture, and contact force. 1 However, there are no standardized methods for HAV exposure assessment. Many studies traditionally have measured acceleration values directly from tools by mounting an accelerometer on the tool handle 2-6 while more recent studies have measured vibration magnitude at the handhandle interface using hand-held/hand-mounted adapters in which an accelerometer is attached to or inserted. 7,8 Most recently, vibration dosimeters integrated with hand adapters 9,10 are available which enable to obtain daily exposure dose while minimizing interference with job activities.Pneumatic tools such as rock drills, grinders, and riveters, and hammers are associated with HAVS. [11][12][13][14] Gasoline-powered grass trimmers, brush cutters, leaf blowers, and chainsaws utilized in many industries including agriculture, forestry, and grounds maintenance are also significant sources of HAV, putting the workers at risk of HAVS. 15 The U.S. Bureau of Labor Statistics (BLS) reported that there
