A field study of exposure to whole-body vibration due to agricultural machines in a full-time rice farmer over one year: Hiroji TSUJIMURA, et al. Division of Occupational and Environmental Health, Department of Social Medicine, Shiga University of Medical Science-Objectives: The aims of this study were to clarify in detail the levels of whole-body vibration (WBV) exposure from a variety of agricultural machines in a rice farmer over one year, and to evaluate the daily level of exposure compared with European and Japanese threshold limits. Methods: The subject was a full-time, male rice farmer. We measured vibration accelerations on the seat pan and at the seat base of four tractors with various implements attached, one rice-planting machine, two combine harvesters, produced by the same manufacturer, and one truck used for transportation of agricultural machines. The position and velocity of the machines were recorded in parallel with WBV measurements. In addition, during the year starting in April 2010, the subject completed a questionnaire regarding his work (date, place, content, hours worked, machines used). We calculated the daily exposure to WBV, A(8), on all the days on which the subject used the agricultural machines. Results: The WBV magnitude in farm fields was relatively high during tasks with high velocity and heavy mechanical load on the machine, and had no dominant axis. The subject worked for 159 days using the agricultural machines during the year, and the proportion of days on which A(8) values exceeded the thresholds was 90% for the Japan occupational exposure limit and 24% for the EU exposure action value. Conclusions: Our findings emphasize the need for rice farmers to have health management strategies suited to the farming seasons and measures to reduce WBV exposure during each farm task.

The prevalence of work related musculoskeletal problems with respect to vibration is prominent. This review paper gather recent studies related to objective assessment among work force from all over the world. The three main objectives of this review are: to analyse published objective assessment related to vibration among the work force; to extract and understand in detail the process of each assessment; and to identify whether or not there is a relationship between each variables. Twenty relevant studies were identified and chosen from electronic databases, dating as far back as 2001. “Vibration”, “musculoskeletal problem”, “worker”, and “objective measures” were the keyword search terms for this paper. Past studies demonstrated various purposes and implementation of objective assessment among the work force in evaluating vibration effects. It provides better understanding for the future researchers and industry to deal with vibration issues among work force. Many objective assessment methods among the work force have been applied in the past studies. However, they are still many concerns found in past studies that need to be investigated in the future studies. Therefore, there is a need to perform and apply different objective assessment for evaluating human vibration issues.

“…[11][12][13][14] Trimming tools with ergonomic features, such as foam or rubber grips or a bent handle design, have proven to be effective in reducing many of these problems. 5,[15][16][17] Environmental factors are also an important consideration in trimming-related injuries. Being struck by or against a tree or branch, falls to a lower level, and electrocutions are important mechanisms of injury during tree trimming, which have received the attention of the National Institute for Occupational Safety and Health and the Centers for Disease Control and Prevention.…”

This is the first study to examine trimming- and pruning-related injuries in the United States using a nationally representative sample. The increasing number and rate of injuries associated with trimming activities in the United States underscore the need for increased prevention efforts, including enhanced safety features of trimming equipment and better education of equipment operators regarding the potential hazards of trimming activities.
