A motosserra, equipamento de alto potencial de risco à segurança e saúde dos operadores, mereceu especial atenção do Governo Federal, visando regulamentar a fabricação, a importação e a venda quanto aos aspectos relativos à segurança. Nesse contexto, está sendo desenvolvido o presente trabalho, cujo objetivo principal é avaliar os níveis de ruído e vibração emitidos por algumas motosserras comercializadas no Brasil. Na fase inicial do trabalho, estudaram-se os métodos internacionais, realizando-se algumas medições para avaliação das dificuldades operacionais. The chain saw is an equipment of high risk to operator's safety and health. Federal government has passed bills regulating the manufacture, import, sale and safety aspects. In this work, we report preliminary results on the vibration and sound pressure level emitted by chain saws commercialized in Brazil. In this initial phase of the work, the international methods and some measurements systems were evaluated as to assess their operational difficulties
