This book explains all of these aspects, combining the authority of an academic textbook with accessible, valuable and practical advice. It identifies the practical measures that can be implemented to address the health implications of occupational exposure to vibration. This is vital because substantial fines for breaking the law can be imposed. Expertly written, and widely researched, it is an indispensable resource. His experience and interest in vibration-related disease extends over 40 years, including clinical practice, teaching, advising industry and specialist groups, writing on the subject and acting as expert witness in legal proceedings. Okay, thank you. The unit is already contributing to health and safety in the workplace. It is involved in performing ergonomics risk assessments in the workplace, doing ergonomics teaching and training for occupational health practitioners and workers, disseminating ergonomics information through brochures and posters and conducting ergonomics research. Information about the unit can be obtained from Busisiwe Nyantumbu, who heads the Ergonomics Unit (e- mail:busisiwe.The vibration damages blood vessels and nerves in the fingers. The affected workers experience numbness and tingling which incapacitate their hands. In South Africa, HAVS has not been recognised despite being compensable under the Compensation for Occupational Injuries and Diseases Act of 1993. Possible reasons could be the lack of awareness about the condition and skills to diagnose it. Recently, a Safety in Mines Research Advisory Committee project on HAVS has established the occurrence of HAVS in South African goldminers. The spinoffs from this study were technology transfer and capacity building in the diagnosis of HAVS in South Africa. Efforts now need to be directed at raising awareness about HAVS, training occupational health practitioners on how to recognize it and most importantly to develop preventive strategies to protect workers from vibration exposure. Another reason could be that local weather conditions are not as cold as in countries such as the United Kingdom where high prevalences of HAVS have been reported. 1 Cold conditions contribute to the development of HAVS and also induce its symptoms 2.https://www.cocreationsmanager.com/blog/ebac-fmax-manual This study, a joint venture of the National Institute for Occupational Health (NIOH), the Medical Bureau for Occupational Diseases and the Health and Safety Laboratory (HSL) in the United Kingdom, was conducted in a hot gold mine. Only rockdrillers were diagnosed with HAVS. The prevalence was found to be low (15), as compared to prevalences of up to 80 in other studies 4,5,6. In this study, a high prevalence of HAVS was expected, considering the high levels of vibration measured in the rockdrills used in the South African mining industry 7. The main reasons given for the low prevalence were the high temperatures underground and the short exposure time to the rockdrill. The study team received training on clinical evaluation and standardised testing for HAVS from experienced occupational health practitioners from the Health and Safety Laboratory in the United Kingdom.Tools associated with HAVS are listed in Table 1. Vibration produced by these tools enters through the hand and is transmitted to the rest of the upper limb. Blood vessels and nerve fibres in the fingers are damaged and the musculo -skeletal system of the upper limb is affected. HAVS has therefore been defined as a disorder affecting the vascular, neurological and musculo -skeletal systems of the upper limb 9. Tactile discrimination and manipulative dexterity are also affected. Symptoms manifest as difficulty in using the hands in everyday activities, such as fastening buttons, writing and milking cows. Job performance may be affected 10. These workers are also prone to accidents 11. As yet the pathophysiology of HAVS has not been elucidated 12. In Figure 1 the white arrows point to blanched tips of the index and middle fingers. As the condition progresses, the rest of the finger becomes affected. Thumbs are rarely affected, and if they are, it usually indicates exposure to high intensity vibration. Areas affected tend to be those in close contact with vibration. As the condition progresses, frequency of attacks increases. During an attack, pain, numbness, reduced manual dexterity and loss of finger coordination are experienced. It is postulated that vibration causes swelling of adjacent tissues which compress the nerve fibres 14. Impaired hand control is not a handicap in everyday activities, but may contribute to an increased risk of accidents 11. Impairment of grip is another common finding in workers with prolonged exposure to vibration. Reduced grip strength is due to a neuromuscular problem which causes incomplete muscle contraction 16. Bone cysts and vacuoles have also been found. These abnormalities are thought to be caused by ergonomic risk factors associated with the use of power tools, namely exertion of force, repetitiveness and awkward postures. Limited information available suggests that neurological symptoms do not improve, but vascular symptoms may improve after several years, provided symptoms were not at a severe stage 17. There is no universally established medical treatment. Different types of physical treatments such as exercise pools and hot packs have been tried 18. Their effect is palliative. Drugs that alleviate the vascular symptoms by causing vasodilation are also available 19. These drugs are not routinely used, because some subjects find it difficult to tolerate their side effects. Evaluation is done by a trained occupational health doctor and a technologist or technician competent in running the standardised tests. In Figure 2 steps in the assessment of HAVS are shown. This assessment method is used in the United Kingdom. In the occupational history, details of all jobs performed by the worker, including their duration, formal, informal and recreational exposure to vibration and duration of exposure are collected. The medical history should elicit signs and symptoms of HAVS, including past and present medical conditions and current medication. Details of daily smoking and alcohol consumption are recorded. Such tests include Allen’s, Tinel’s, Phalen’s, Adson’s, Purdue pegboard and grip strength. Tinel’s and Phalen’s tests elicit symptoms of carpal tunnel compression. Adson’s test detects obstruction to arterial flow in the arm at the level of the neck. The Purdue pegboard assesses dexterity of hands and fingers. Finally, grip strength assesses muscle strength of hands and fingers. Two are for neurological damage, and one for vascular damage. The index and little fingers of both hands are tested. Warm and cool thresholds are recorded from responses of the subject. Temperature Neutral Zone (TNZ), which is the temperature that the subject cannot perceive, is obtained from the difference between warm and cool thresholds.As with the TA, the index and little fingers of both hands are tested. VT has a probe where two vibration frequencies (31,5 Hz and 125 Hz) are applied. The subject places the tested finger on the probe and when vibration is felt, a response button is pressed. When vibration dissipates, the response button is released. Vibration thresholds are calculated from the subject’s responses.Fingers of both hands are tested, except for thumbs. Hands are then removed from the waterbath and allowed to rewarm for 10 minutes. Damage to the blood vessels is indicated by long rewarming times of more than 300 seconds. Staging is done for both the neurological and vascular components of HAVS. Maximum total score for the two tests is 16, which correlates with stage 2SN (late).Thumbs are rarely affected. If they are, the score of each hand could go up to 33. These controls are elimination, substitution, engineering, administrative and personal protective equipment. Others are aimed at reducing exposure and are commonly used to protect vibration exposed workers. These tools are called anti-vibration tools, for example anti-vibration chainsaws. The principles engineers apply when developing anti-vibration tools are isolation and damping. Isolation removes most of the vibration before it reaches the operator’s hand. Damping converts vibration energy to heat. Development of remote controlled vibrating hand tools is ideal in preventing the operator from being exposed to vibration. If workers are multi-skilled, rotation becomes more viable. Best practice includes maintaining tools regularly, gripping tools lightly, operating the tool when necessary and at reduced speeds, keeping hands warm and stopping smoking. If symptoms of HAVS appear, they should be reported immediately. Workers who have HAVS can be detected early through a medical surveillance program. Medical surveillance also helps identifying workers at high risk, so that they are placed in jobs that will not expose them to vibration. However, medical surveillance for HAVS requires a screening tool which is as yet not available in South Africa. For prevention and control of vibration exposure, anti-vibration gloves have been used. Their effectiveness in attenuating vibration is questionable 22,23. Therefore, their use is not recommended. Now that we are aware of the condition, efforts should be directed at prevention and control of vibration exposure24. More work still needs to be done to raise awareness about the condition. There is also a need to educate and train more occupational health practitioners on the clinical diagnosis of HAVS. The NIOH is grateful to SIMRAC for donating the HAVS equipment. Workers, who are suspected of having HAVS, can now be referred to the NIOH HAVS centre for assessment. Johannesburg: Safety in Mines Research Advisory Committee; 2002.

Twenty symptomatic male workers (aged 28 to 65 years) subjected to vibration by hand-held tools were interviewed about subjective symptoms and activities of daily living and were assessed with a battery of objective tests for sensibility, dexterity, grip function, and grip strength. The test results were compared with normative data. The majority of patients complained of cold intolerance, numbness, pain, sensory impairment, and difficulties in handling manual tools and in handwriting. The various objective tests showed considerable variation in indications of pathologic outcome, revealing differences in sensitivity to detect impaired hand function. Semmes-Weinstein monofilament testing for perception of light touch-deep pressure sensation, the small-object shape identification test, and moving two-point discrimination testing for functional sensibility provided the most indications of pathologic outcomes. The authors conclude that vibration-exposed patients present considerable impairment in hand function. Published by Elsevier Inc. All rights reserved. Recommended articles No articles found.

Citations (3) References (9) Abstract Hand-arm vibration syndrome has been reported in the literature to occur following exposure to vibration from the use of many tools, but to date there have been no case reports of its occurrence in workers who have used high-pressure hoses, alone or with other tools. To remedy this, the case histories of nine subjects (two without mixed exposure) examined in the UK and Canada are presented, together with their severity classified according to the Stockholm scales. Attention is drawn to the need to use multiple diagnostic tests to establish the diagnosis and the need to implement vibration isolation and damping methodologies, as and when feasible, with respect to hose nozzles in order to minimize the hazard. The respective risk levels are presented, together with vibration measurements on hoses used by some of the cases.

Shah Traumatic vasospastic disease commonly results from repetitive trauma, including vibration, mechanical percussive injury to the hands, significant cold exposure, or electric shock injury. Traumatic vasospastic disease is a common cause of Raynaud’s phenomenon in men. The prevalence varies across geographic regions, and this is a function of local climates and different occupational exposures. A careful review of occupational, leisure, and environmental exposures is critical in the assessment of patients with Raynaud’s phenomenon. If traumatic vasospastic disease is suspected, referral to an occupational health physician should be considered. To the extent possible, the exposure should be eliminated, and patients should avoid cold temperatures to prevent vasospastic episodes and morbidity.

View Show abstract Sensorineural Stages of the Hand-Arm Vibration Syndrome Article Full-text available Sep 1987 SCAND J WORK ENV HEA Anthony J Brammer W Taylor G Lundborg Recent work has shown that the vascular signs and neurological symptoms commonly associated with exposure of the hand to vibration may develop independently. A classification for the neurological component of the hand-arm vibration syndrome has been developed for those symptoms dominated by sensory afferent involvement, based on the results of objective tests on 634 hands. Consistent implementation of this classification by means of objective tests requires one, or more, precise, quantitative measure of peripheral somatosensory dysfunction, in addition to the traditional neurological tests (fine touch, pain, and temperature). Measurements of tactile function by means of esthesiometry or vibrotactile perception appear suited to this purpose.

Loriga View The Stockholm Workshop Scale for the Classification of Cold-Induced Raynaud's Phenomenon in the Hand-Arm Vibration Syndrome Article Sep 1987 SCAND J WORK ENV HEA G Gemne I Pyykko W. Taylor P L Pelmear On the basis of experience accumulated over the past few years, a revision has been made in the currently used Taylor-Pelmear scale for the staging of Raynaud's phenomenon in persons exposed to vibration from hand-held tools, while retaining as much as possible of the well-established advantages of the scale for research and its proved usefulness for clinical and medicolegal purposes. The 0T and 0N stages of symptoms have been omitted, together with the parallel disability scale. The criteria descriptions have been changed so as to minimize their reliance on seasonal factors. The new staging system--a stage 0 and four stages (1-4) with attacks of cold-induced Raynaud's phenomenon--clearly defines the differences in the descriptions of the stage criteria in order to improve their clinical usefulness. A numerical scoring based on the extent and distribution of finger blanching was not, however, introduced, whereas a score based on the number of affected fingers on each hand was proposed, considered, and accepted.

Wills The case histories of ten workers with Hand-Arm Vibration Syndrome (HAVS) indicate that their predominant vibration exposure was to impact vibration. This association, recognized previously in pedestal grinders and in multiple hand tool users, should now be identified in spot welders and press operators. This will have important implications for compensation claimants as well as prevention development.

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.

We will be back on 3 January 2017 But occupational health also has a pivotal role to play in terms of understanding and evaluating the outcome of these assessments, and providing the leadership to create a collaborative, co-ordinated approach, as Anne Harriss and Nancy Njuguna explain. Sustained exposure is associated with permanent effects on anatomical structures in the hands and arms, which may lead to hand-arm vibration syndrome (HAVS) that impacts on both quality of life and work performance (Jordan et al, 2005; House et al, 2014). For example, Thanet District Council was fined ?2.5 million for failing to protect workers against HAV related diseases in 2016. In 2012 Audio Medical Services (AMS) was prosecuted by the HSE for using staff lacking proper qualifications for HAVS health surveillance. AMS did not refer employees to OH professionals when required, neither did it provide employers with adequate information enabling them to comply with their duty of care and prevent further deterioration of workers’ health ( Personnel Today, 2012). The Control of Vibration at Work Regulations 2005 require employers to assess and control the transmission of vibration from work processes and power tools to workers’ hands, arms and fingers (Harada and Mahbub, 2008). However, powered tools are also commonly used in healthcare, particularly within plaster rooms, dental and orthopaedic surgery (Aw et al, 2008). A survey of orthopaedic surgeons indicated that some exhibited symptoms of HAVS from their use of power tools and, yet, these incidents were under reported (Roberts et al, 2007). In severe cases the worker may be diagnosed with HAVS, symptoms of which include tingling, paraesthesia and digit blanching (Heaver et al, 2011). Smoking, treatment with beta-blockers and exposure to cold exacerbate these symptoms. For workers exposed to vibration, the Control of Vibration at Work Regulations 2005 require further vibration-specific risk assessments. Equipment manuals will provide details of vibration values; These include pain, numbness or circulatory problems; and They should be observed when carrying out their tasks as their posture and techniques may increase their vibration exposure. Poor design of equipment coupled with awkward working positions may intensify the effects on the hands and arms. Tools that put workers at risk should be replaced with alternatives that produce lower magnitudes of vibration. Other than for occasional, emergency work, personal vibration exposure must not exceed the limit set by the Control of Vibration at Work Regulations (2005) and detailed later in this article. This can be done through job rotation and ensuring regular breaks are taken. These should include the need to participate in health surveillance programmes and how to recognise and report the health effects of vibration. Should improvements be necessary, an action plan with further control measures should be made. Risk assessments should be reviewed at least annually, or when there are changes to work processes that may affect vibration exposure. The regulations set a daily exposure action value (EAV) and an exposure limit value (ELV), which are calculated over the equivalent of an eight-hour working day. However, in emergency situations, such as responses to serious incidents, weekly averaging of daily exposures is allowable under the proviso that daily exposures remain below the ELV and, on most days, exposures remain below the EAV. Once diagnosed, HAVS is reportable under Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995. Those with HAVS are able to claim Industrial Injuries Disablement Benefit, reflecting the significance of this disabling condition. Damage may generally be unnoticeable during the initial stages and in mild cases symptoms are intermittent and only affect the fingertips. However, with continued exposure the frequency of attacks increases and the effects become more obvious (HSE, 2013). Colour change in the figures reflects vascular changes: pallor resulting from tissue hypoxia, blue discolouration from deoxygenation and redness which occurs following reperfusion (Murphy et al, 2000).
