“…Vibration exposure in terms of daily duration and A(8) W hi (ie, weighted with the four alternative frequency weightings of acceleration magnitude) was greater among the stone workers than forestry operators, although duration of exposure (years) was similar in the two groups. Frequency spectra from the hand-held tools used by the HTV-exposed workers (5), and the results from table 1 show that the stone workers were more exposed to high frequency vibration than the forestry workers.…”

“…Acceleration magnitudes were weighted using the frequency weightings displayed in figure 1 (11): W h is the frequency weighting specified in ISO 5349-1 (2); W h-bl is the band-limiting component of W h (10); W hf is a frequency weighting based on biodynamic studies of finger vibration power absorption (12); and W hT is a frequency weighting based on a Japanese study of VWF prevalence in worker groups investigated from 1957-1977 (13 The results of tool rms acceleration measurements with the four alternative frequency weightings are reported in a previous study (5).…”

“…Case definition did not include subjects who reported temporary presence of tingling or numbness occurring while or after working with vibratory tools, during or following episodes of VWF or exposures to cold environment (8). The diagnosis of VWF was based on the findings of the medical interview assisted by color charts according to the criteria established by the Stockholm Workshop 1994 (5).…”

“…In a previous study, we tested the performance of four alternative frequency weightings to predict the occurrence of VWF in a cohort of HTV-exposed workers recruited within the EU project VIBRISKS (4,5). It was shown that measures of daily vibration exposure, which give relatively more weight to intermediate and high frequency vibration, were more appropriate for assessing the probability of VWF than a measure based on the current ISO frequency weighting.…”

Human exposure to hand‐arm vibration arises from occupational use of vibrating hand‐held, hand‐guided, or hand‐fed machines. Exposure is associated with the development of sensorineural, vascular, and musculoskeletal disorders, collectively known as the hand‐arm vibration syndrome (HAVS). The standardized methods, and their limitations, for measurement and evaluation of worker vibration exposure and the vibration emission of machinery are discussed. Disabling cases of HAVS are preventable if employers apply good practice to minimize risk and provide health surveillance for workers at risk; this chapter discusses risk assessment for HAVS and the control of that risk, giving examples of good practice. Exposure limits and action levels laid down in national legislation or guidance, in the European Union, Japan, and the United States, are discussed and compared.

Pneumatic tools and rotating tools, such as grinders have been recorded as being used in many countries. Poorly maintained tools are well‐established causes of significantly increased transmission of vibrational energy into the hands of workers causing episodic finger blanching, symptoms of numbness and tingling and neurosensory deficit in the hands, and loss of grip strength. Collectively these health problems are termed HAVS and can become significantly disabling in severer cases. The term HAVS began to have widespread coinage as describing the range of vascular, neurosensory, and musculoskeletal problems associated with excessive exposure to HTV. There have been a number of reports that address the possible pathophysiological basis of the elements of HAVS. However, the exact relationship between the dose and either the vascular or neurosensory elements of HAVS has remained unclear as to how much the nature of the exposure data, often relying on retrospective exposure assessment, or the extent of individual susceptibility adds to the uncertainty or noise in any reported relationships. There has been considerable international effort to reduce exposures, especially through better ergonomically designed tools with lower vibration emissions.
