Download or read book Hand arm vibration Exposures to isolated and repeated shock vibrations written by Paul Pitts and published by DGUV/IFA. This book was released on 2017-09-01 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: ISO 5349, developed by ISO Technical Committee ISO/TC 108, “Mechanical vibration and shock”, is the generic standard for the measurement and assessment of human vibration exposure. Ever since it was originally published in 1986, this standard has been unclear in its assessment of repeated isolated shocks. The current version of ISO 5349-1:2001 states in its scope that the time dependency for human response to repeated shocks is not fully known. Caution is therefore advised in the application of this part of ISO 5349 to such vibration (isolated shocks). In response to an initiative on the part of the ISO/TC 108 Technical Committee, a workshop was held at the 13th International Conference on Hand-Arm Vibration in Beijing in 2015 for the purpose of determining the current state of knowledge concerning exposure to repeated isolated shock vibration caused by machinery and tools and its pathophysiological and epidemiological assessment, and evaluating gaps in knowledge in the interests of future research activity. This report contains the papers presented at the workshop. Part I provides an overview of the results of the workshop and of details of two papers. Part II contains a research report containing background information on two further papers presented at the workshop.

This book was released on 2019-11-20 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Project Report from the year 2010 in the subject Health - Public Health, grade: N/A, University of Botswana, language: English, abstract: This research project is about the Hand-Arm Vibration Syndrome (HAVS) which construction workers suffer from. Are the daily exposure levels of vibration to which construction workers are exposed within acceptable limits? HAVS is a group of symptoms related to the use of equipment and tools that vibrate. Symptoms range from vascular and neurological to musculoskeletal, and affect different parts of the hand-arm system. Vibration is the oscillatory motion of bodies. It is divided into hand transmitted vibration, which is vibration entering the body through hands, and whole-body vibration, which enters the body when it is supported by some vibrating surface. There are over 8 million workers that are exposed to vibration, and as an occupational hazard, it is not given much attention in Botswana and in most parts of the developing world. A quantitative cross-sectional study design was used since there were different groups whose results were compared. The vibrometer was be used to quantify the daily vibration levels in each sample population, and the questionnaire distributed provided additional information as to the presence of symptoms or history of any discomfort resulting from the type of work. The population of interest includes the workers at a construction site within the University of Botswana, and these were divided into 5 groups, each group comprised 2 to 3 workers selected systematically, from whom data was collected depending on the tools available on the construction site. This means that the study population was 15. When one looks at its negative effects on the human body, which range from simple nausea to HAVS, it is safe to say that vibration is not getting the attention it needs. Various technical developments in society have led to an increase in the number and types of sources of vibration to which people are exposed.

This book was released on 2016 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to hand-transmitted vibration (HTV) arising from operating hand-held power tools has been associated with various health consequences such as vascular, neurological and musculoskeletal disorders of the hand-arm system, which are collectively termed as hand-arm vibration syndrome (HAVS). In order to decrease the effects of HTV, substantial efforts have been made to protect the operator from the vibrating tools and decrease the vibration exposure. One of the convenient means to isolate the hand from the vibrating tool handle is the anti-vibration (AV) glove. These gloves are constructed from different isolation materials, which are capable of reducing the vibration transmitted to the hands. Vibration isolation performance of AV gloves has been widely evaluated based on measurements of vibration transmitted to the palm of the hand following the method recommended in ISO 10819 (2013). The standard does not require the measurement of transmitted vibration at the fingers side, and consider similar vibration isolation performance of the gloves at the palm and the fingers. The standard also does not address the effect of AV gloves on the hand grip strength, which can be a reason for not wearing these gloves by tool operators. This dissertation seeks to develop a finger adapter capable of measuring the transmitted vibration to fingers and assess the AV gloves based on the integrated performance of vibration isolation at palm and fingers as well as the grip strength preservation. Three different finger adapters (a steel ring, a split ring and a Velcro adapter), each instrumented with a tri-axial accelerometer, were developed and assessed to measure the vibration transmitted to the index and the middle fingers. The assessment of the three adapters showed that the Velcro adapter exhibit relatively lower inter-subject variability and yields resonably good agreements with the data reported in a recent study that measured fingers vibration using laser vibrometer. The effectiveness of the Velcro finger adapters was further explored through their ability of generating repeatable and reproducible vibration measurements. Good repeatability was observed from the vibration transmissibility measured during three trials perfromed with bare hand fingers. In the reproducibility tests, the subjects were asked to remove and reinstall the finger adapters between the trials. The assessment results showed that the obtained vibration transmissibility measurements were reproducible within each subject. In order to enhance the understanding of fingers vibration, an investigation was conducted through measurements of vibration transmissibility of four different vibration reducing (VR) gloves at the middle phalanges of index and middle fingers using two Velcro finger adapters. Four male subjects participated in the measurements, which were conducted under the standardized vibration spectrum and the spectra of three different hand tools. Vibration transmissibility of the gloves were also measured at the palm using the standardized palm adapter. The frequency response functions (FRFs) of gloves at the index and middle fingers were utilized to estimate the vibration transmissibility of the gloves under different tool spectra. Only two gloves would be considered as AV gloves, although these showed fingers vibration amplification. The FRF method of estimating fingers vibration responses resulted in reliable prediction of the perfromance for different tools. Furthermore, 12 male subjects participated for assessment of integrated performance of 12 different VR gloves in terms of vibration transmission performance at the palm and fingers, as well as the effect of gloves on the grip strength preservation. The grip strength magnitude was measured using the cylindrical handle utilized in the vibration transmissibility measurements. The overall vibration transmissibility of the gloves at the fingers were obtained using the frequency weighting recommended in the standard and the reported fingers weighting. All the gloves attenuated fingers vibration in the 10–200 Hz frequency range, with exception of only two gloves. At greater frequencies (>200Hz), majority of the gloves amplified the middle finger transmitted vibration, while only a few gloves showed vibration amplification at the index finger. The effect of different frequency weightings on the vibration isolation performance of gloves at the fingers was only evident in the high frequency range (200–1250Hz). Only four gloves passed the standardized screening criteria despite their vibration amplification at the fingers. All the gloves resulted in reduced hand grip strength with only one exception.

This book was released on 2019-05-30 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: In May 2019, the Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung (IFA) was hosting the 14th International Conference on Hand-Arm-Vibration. The event is organised every four years under the auspices of international expert bodies at changing places. It is aimed at all stakeholders in the subject, whether experts from the occupational safety and health and research communities or management personnel in the areas of manufacture and design. Mechanized manual work is often associated with exposure to vibration that may impact adversely upon the health and well-being of the affected individuals. Besides impairments to comfort and performance, harm to the hand-arm system, possibly permanent, must be prevented as a matter of priority. In a world of work that is becoming more and more complex, combined exposures are also becoming increasingly relevant. What influence does hand-arm vibration have in conjunction with noise or whole-body vibration? What contribution can be made by medicine, diagnostics, epidemiology, measurement technology and prevention to the identification and containment of risks, and better still, to their elimination? What is the role of international regulatory activity in this context? The 14th International Conference on Hand-Arm Vibration aimed to address these and many other questions concerning hand-arm vibration, and to find answers relevant to the field.

Download or read book Musculoskeletal Disorders and the Workplace written by Institute of Medicine and published by National Academies Press. This book was released on 2001-05-24 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year workers' low-back, hand, and arm problems lead to time away from jobs and reduce the nation's economic productivity. The connection of these problems to workplace activities-from carrying boxes to lifting patients to pounding computer keyboards-is the subject of major disagreements among workers, employers, advocacy groups, and researchers. Musculoskeletal Disorders and the Workplace examines the scientific basis for connecting musculoskeletal disorders with the workplace, considering people, job tasks, and work environments. A multidisciplinary panel draws conclusions about the likelihood of causal links and the effectiveness of various intervention strategies. The panel also offers recommendations for what actions can be considered on the basis of current information and for closing information gaps. This book presents the latest information on the prevalence, incidence, and costs of musculoskeletal disorders and identifies factors that influence injury reporting. It reviews the broad scope of evidence: epidemiological studies of physical and psychosocial variables, basic biology, biomechanics, and physical and behavioral responses to stress. Given the magnitude of the problem-approximately 1 million people miss some work each year-and the current trends in workplace practices, this volume will be a must for advocates for workplace health, policy makers, employers, employees, medical professionals, engineers, lawyers, and labor officials.
