“…In this study, the metric A p (8) performed better than A h (8) for the assessment of the vasoconstrictor effect of cold in the digital arteries of HTV workers. This is consistent with our previous epidemiological findings that A p (8) was a better predictor of the occurrence over time of VWF symptoms in the VIBRISKS cohort compared to the measure of daily vibration exposure A h (8) recommended by ISO 5349-1 [4]. Vascular investigations have revealed that acute exposure to vibrations with equal frequency-weighted acceleration magnitudes can provoke a stronger reduction in the blood flow of the human finger for frequencies between 31.5 and 250 Hz compared with vibration at 16 Hz [7].…”

“…These findings are in contrast with the frequency weighting W h recommended by the ISO 5349-1 standard, which gives more weight to lower-frequency vibrations (≤16 Hz) in the assessment of vibration-induced health disorders [3]. In the Italian arm of the EU VIBRISKS project [4], a supplementary hand-arm vascular weighting (W p ) proposed in the ISO/TR 18570 [5], which assigns more weight to intermediate-and high-frequency vibration (Figure 1), performed better than the ISO W h curve for the prediction of the occurrence of subjective symptoms of VWF in a cohort of HTV workers.…”

Powered-hand tools and vibration-related disorders in US-railway maintenance-of-way workers

Maintenance-of-way workers in North America who construct railroad tracks utilize specialized powered-hand tools, which lead to hand-transmitted vibration exposure. In this study, the maintenance-of-way workers were surveyed about neuro-musculoskeletal disorders, powered-hand tools and work practices. Information about vibration emission data of trade specific powered-hand tools for the North American and European Union markets was searched online to obtain respective user information of manufacturer and compared to non-commercial international data banks. The survey showed that maintenance-of-way workers frequently reported typical hand-transmitted vibration-related symptoms, and appear to be at a risk for neuro-musculoskeletal disorders of the upper extremity. Of all of the powered-hand tools used by this trade, 88% of the selected tools exceeded a=5 m/s 2 and were above vibration magnitudes of common tools of other comparable industries. This may create a risk if these tools are used throughout an 8-h work day and management of vibration exposure may be needed. In the North-American market, limited or no vibration emission data is available from manufacturers or distributors. Vibration emission information for powered-hand tools, including vibration emission levels (in m/s 2 ), uncertainty factor K, and the applied testing standard/norm may assist employers, users and occupational health providers to better assess, compare and manage risk.

Findings showed that W p performed better than the ISO W h for the prediction of the incidence of subjective symptoms of VWF in a cohort of HTV workers ( Fig.…”

This study compared the relative performance of alternative frequency weightings of hand-transmitted vibration (HTV) to predict the extent of cold-induced vasoconstriction in the digital arteries of HTV workers. The cold response of digital arteries was related to measures of daily vibration exposure expressed in terms of r.m.s. acceleration magnitude normalised to an 8-h day, frequency weighted according to either the frequency weighting W h defined in international standard ISO 5349-1:2001 ( A h (8) in ms −2 r.m.s.) or the hand-arm vascular frequency weighting W p proposed in the ISO Technical Report 18570:2007 ( A p (8) in ms −2 r.m.s.). The measure of daily vibration exposure constructed with the frequency weighting W p ( A p (8)) was a better predictor of the cold response of the digital arteries in the HTV workers than the metric derived from the conventional ISO frequency weighting W h ( A h (8)). This finding suggests that a measure of daily vibration exposure constructed with the vascular weighting W p , which gives more weight to intermediate- and high-frequency vibration (31.5−250 Hz), performed better for the prediction of cold induced digital arterial hyperresponsiveness than that obtained with the frequency weighting W h recommended in ISO 5349-1 which gives more importance to lower frequency vibration (≤16 Hz).
