Abstract
Objective:
Determine the impact caused by the type of tool and type of glove on the transmissibility of the hand-arm vibration.
Methods:
An experimental design was carried out for workers in the hydrocarbon sector, in order to identify the global transmissibility of gloves in different activities. The measurements were made through two accelerometers: one installed in the machine and the other in the palm of the hand. The transmissibility was calculated in the fre quency range 0-2 kHz, for five types of tools and 3 types of gloves. Finally, the exposure times to which the worker may be exposed with the use of gloves were compared.
Results:
The effectiveness of the gloves was identified to protect the workers, allowing them to work a greater number of hours per day. The statistical analysis shows that the variable type of tool has a significant effect on transmissibility, while the type of glove does not have any statistical effect. The study presents the percentages of increase in exposure times and the study of transmissibilities.
Conclusions:
The three types of gloves evaluated showed an effec tive performance as vibration attenuators. The increase of the expo sure time allowed when wearing gloves is very significant for all tools.
