The article presents a comparison of the results of human exposure to hand-arm vibration in case of using gloves. The analyzed case was assessed by two methods, i.e., performed by conventional method (including the criterion of accelerations of vibrations) and energy method (based on the dose of energy flowing through the human during the operation of the tool). The analyzes were based on the results of the theoretical studies of biodynamics and energy flow in the human - tool system. The models of the human and the glove, specified in the ISO 10068:2012 standard, were used for this purpose. The analysis showed that results of the evaluation of the impact of gloves on human protection obtained between both methods are different. The article presents the analytical results and differences in the assessment of human exposure to hand-arm vibrations, using both methods, as an example for a situation, in which an operator works with mechanized handheld tool.
