Abstract
Diverse industrial sectors are used motorized manual tools, which generate hands and arms vibration (HAV’s) on operators, and forklift transport equipment, which expose the worker to whole body vibration. For these situations is necessary to evaluate whether the exposure limit vibrations has been exceeded, as there may be damage to the human body and occupational health of operators. This article was aimed at evaluating the occupational exposure of some workers to physical agent vibration. The study was founded basis the Brazilian standardisation, responsible for regulating and vibration control, based on the data collect from a boiler making company. The analysis on the located vibration exposure in hands and arms, measurements were done on angle grinders of different working levels. The whole body vibration analysis was done by measuring vibration on a forklift. During the use of almost all sanders, the workers had the exposure limits to accelerations exceeded, requiring immediate corrective actions. Already when used the forklift, the vibration exposure was between the exposure limit and level of action, requiring only taken preventative actions. The study increased our awareness about the need to preserve the occupational workers’s health about vibrations exposure and also advise the company the importance of mitigating these impacts releasing the company of additional unhealthy provided in standard NR-15-Annex 8.
