Vibration syndrome in chipping and grinding workers.
J Occup Med 1984 Oct; 26(10):765-788
This review of vibration syndrome discussed several epidemiologic studies, engineering techniques used to prevent vibration syndrome, and physiologic testing with emphasis on aesthesiometry, photocell plethysmography, and radiographic testing. Recent studies confirmed that vibration syndrome is a problem in the United States. Foundry workers demonstrated severe cases of vibration syndrome with short latencies and high prevalence of the advanced stages. When studying various tools, it appeared that a reduction of throttle level decreased the vibration levels measured on chipping hammers. For grinders, the working condition of the tool affected the measured vibration acceleration levels. Emphasis was placed on preplacement medical examinations to identify workers predisposed to or experiencing Raynaud's phenomenon or disease, education of workers regarding the signs and symptoms of the disease, and engineering improvements such as increased quality control on castings to reduce finishing time and automation of the finishing process. Studies need to be conducted to determine the best times for rest breaks and job rotation. The warming of the worker's hands is also important and the use of gloves affects the occurrence of vibration syndrome.
