"Haul truck drivers at surface mines are exposed to whole-body vibration for extended periods. Thirty-two whole-body vibration measurements were gathered from haul trucks under a range of normal operating conditions. Measurements taken from 30 of the 32 trucks fell within the health guidance caution zone defined by ISO2631-1 for an 8 h daily exposure suggesting, according to ISO2631-1, that “caution with respect to potential health risks is indicated”. Maintained roadways were associated with substantially lower vibration amplitudes. Larger trucks were associated with lower vibration levels than small trucks. The descriptive nature of the research, and small sample size, prevents any strong conclusion regarding causal links. Further investigation of the variables associated with elevated vibration levels is justified."

"La conférence scientifique internationale "Effets sur la santé des vibrations transmises à l'enseble du corps, qui s'est tenue à Amsterdam en juin 2013, a abordé les thèmes des maladies professionnelles, des mesures d'exposition et de la modélisation des effets des vibrations sur l'homme. Plusieurs études épidémiologiques, expériences et exemples de mesures concrètes de prévention ont fait l'objet d'échanges scientifiques susceptibles d'aider les chargés de prévention dans leur mission de réduction des effets des vibrations sur la santé."

This article reviews the health effects, treatment, prevention strategies, and international standards for hand-arm vibration syndrome (HAVS). It draws attention to the proposed International Standards Organization (ISO) 1998 revision requirement to base the assessment of vibration on the root-sum-of-squares for all directions rather than the dominant direction; the European Economic Commission (EEC) directives with their threshold, action, and ceiling levels; and the intent of the EEC, United Kingdom, and Japanese jurisdictions to propose action levels to prevent the incidence of vibration-induced Raynaud's phenomenon (VWF) from exceeding the background level in their countries. Proposals for the revision of the American Conference of Governmental Industrial Hygienists (ACGIH®) Threshold Limit Values (TLV®s) are presented.

Background Although some occupational sources of hand-transmitted vibration (HTV) have been extensively investigated, the risks associated with others are poorly characterized. Methods A questionnaire was mailed to a community sample of 12,240 men aged 16- 64 years and 906 men from the armed forces. Questions covered current occupation, sources of HTV, numbness or tingling in the fingers in the past week, and finger blanching. In the 5,364 respondents who had been at work in the past week, associations between symptoms and exposures were examined by logistic regression, with odds ratios converted into prevalence ratios (PRs). Results Altogether, 513 men (10%) reported cold-induced finger blanching and 769 (14%) sensory symptoms in the fingers. The risk of blanching was increased in builders (PR 2.4, 95% CI 1.0-5.2), carpenters and joiners (PR 1.9, 95% CI 1.0-3.4), motor mechanics (PR 2.3, 95% CI 1.1-4.6), and laborers (PR 2.8, 95% CI 1.3-6.0); while the risk of sensory symptoms was elevated in laborers (PR 4.0, 95% CI 2.3-6.6) and plant operatives (PR 3.5, 95% CI 1.9-5.9). Use of hand-guided mowers, concrete breakers, chain saws, and jig saws was significantly associated with symptoms. Conclusions Little attention has been paid to the risks of vibration injury in construction workers, woodworkers, motor mechanics, and laborers, or to the risks from mowers, jig saws and several other common vibratory tools. These should be a focus for further investigation and preventive measures

"La pubblicazione considera le vibrazioni correlate alle patologie professionali di rilevante interesse assicurativo.
In particolare la sindrome di Raynaud e quella del tunnel carpale sono indotte dagli sforzi correlati al sistema mano-braccio, mentre le patologie del rachide sono le sole correlabili alle sollecitazioni trasmesse dal corpo intero.
Tali patologie dipendono tuttavia sia dall'uso di strumenti vibranti sia da altre fonti quali, ad esempio, la movimentazione di carichi notevoli.
In ausilio alla guida sono stati inoltre creati fogli elettronici per l'elaborazione degli indici revisionali indicativi (es. probabilità di insorgenza della malattia in base agli anni di esposizione; anni necessari alla probabilità del 10% di insorgenza della patologia). "
