Análise de vibração ocupacional de corpo inteiro e mãos e braços em empilhadeira industrial para critérios de julgamento profissional

Abstract

The workers of industries are constantly exposed to occupational risks, that they can be presented to them in chemical agents' form with concentration above the limit of tolerance, in the biological agents' form that are linked directly at the time of exhibition and in the physical agents' form, that is evaluated in agreement with his/her intensity. All of the risks, when in exhibition increased, they cause irreversible damages the human health. The occupational vibration of whole (VCI) body and of hands and arms (VMB) are physical risks that affect the human being when in contact with vehicles in the transport of the same, such activity is generating source of complex occupational vibration for at least four points of the human body. Those evaluations are accomplished in agreement with the parameters of ISO2631-1 and ISO5349 that are suitable in Brazil for NR-15 and for the Norms of Occupational (NHO) Hygiene. The study involved sixteen vehicles of the type forklift of several models in even industrial floor of concrete, and the measurements followed the methodologies of NHO-09 and NHO-10, being of that sorts out possible to lift the vibration indexes quantitatively VMB and VCI and to tabulate data, and the parameters of collected indexes come to corroborate with the criterion of professional judgement for meter of vibration of only channel.
