Análise de riscos e adequação à NR-12 de uma máquina de beneficiamento de sementes

Abstract

Seed selection machines are of paramount importance to the improvement of planting, but for having many of these movements can become a risk to your operator. The goal is to verify if the current conditions meet, NR12 and possible case have solutions thatcan be effectively put into practice and to eliminate or reduce risks to make adjustments that make the machine more secure. The methodology for risk analysis of a seed sorting machine was to determine which risks that can affect a worker that the opera. Using the NR12 as the basis, the various risks that have been resolved or mitigated. To determine the risks and their implications came in command category sought. To follow all the steps determined by standard was used the standard ABNT NBR 12,100:2013 that details the risks. The ABNT NBR 14,153:2013 has a flowchart to achieve control category, which the machine belongs. The result was the determination of the risks that could endanger the physical health of the first mechanical work with the grasping and crushing which are the most common risks and the electrical risks as exposed wiring and lack of signposting for danger zone. After determining, the risk comes the solution and the discussion of its technical viabilities. After the whole process of assessment and discussion of the solutions come from the adjustments themselves made the machine that was first categorized into 3 and after the measures taken the machine dropped to category 1.
