“…It should be noted, however, that in small garages with only one or two workers, mechanics may combine mechanical work with car body repair and car painting, which would increase exposure to vibration. 14 The mechanics in the present study did not do any car body repair or spray painting of cars. The standardised clinical assessment, using the Stockholm Workshop scale, facilitated comparisons with other studies performed using this scale.…”

“…A study with the tools used by our mechanics would have been preferable. However, another study on nut-runners, performed by Hansson and colleagues, 14 with subjects tightening and loosening car wheel nuts showed very similar results. The median vibration level in that study was 4 m/s 2 , while the most common tool used by our mechanics (CP 734), had a level of 3.5 m/s 2 , identical to the result for this tool in the larger study by Ekholm and Falk.…”

Aims: To assess the occurrence of hand-arm vibration syndrome (HAVS) in Swedish car mechanics, and the relation between HAVS and duration of exposure. Methods: A total of 806 mechanics answered a questionnaire on vascular and neurological symptoms, and exposure to vibrations. Mechanics with symptoms, and some mechanics without symptoms, were invited to a clinical examination, including also a timed Allen test. Vascular and neurological symptoms were classified using the Stockholm Workshop scales. The mean daily exposure (mainly using nut-runners) was 14 minutes and the mean exposure duration, 12 years. Published data have shown vibration levels in nut-runners of about 3.5 m/s 2 . Results: In the questionnaire, 24% reported cold induced white finger (WF), 25% persistent numbness, and 13%, reduced grip force. The clinical examination showed a prevalence of vibration induced white finger (VWF) of about 15%, mainly in stage 2, and after 20 years, of 25%. A survival analysis showed similar results. We found that the International Organisation for Standardisation (ISO) model underestimates the risk of VWF. The incidence after 1975 was 19 cases per 1000 person-years. Slow refill times in the timed Allen test were common (15% had a refill time of >20 seconds), and associated with the presence of VWF. The clinical examination revealed neurological symptoms in the hands in about 25% of subjects, mainly at stage 2. After 20 years, the prevalence was 40%. The questionnaire items on WF and numbness both showed likelihood ratios of 13. Conclusion: HAVS is common among Swedish car mechanics in spite of short daily exposure times. This underlines the need for preventive measures.

“…This method deals only with the load on the musculoskeletal system caused by poor working postures. Other sources contributing to the total ergonomie body burden, e.g., vibrations, which in some cases may be of importance[Hansson et al 1987], are neglected. The original OWAS method was developed by the Ovako Oy Steel Co. in Finland, and has been described in several papers; only a few applications of OWAS have been published (Karhu et al 1 9 8 1 ,].…”
