Abstract

According to the European directive 44/2002/CE the occupational exposure to mechanical vibration may be assessed by using relevant information on the probable magnitude of the vibration transmitted by the equipment in use, including those information provided by the manufacturer. However, such information has to be consistent with the specific working practices considered, while the vibration emission indicated by the manufacturer refer to standard operating conditions. When considering hand-arm vibration, the number of variables which affect the actual acceleration measured at the tool handles is considerable. This article discusses the results of the vibration measurements taken from a variety of hand-held power tools used for secondary activities serving mining, mine site rehabilitation and construction work.
