NR-12 em prensa dobradeira hidraulica de chapas em uma indústria de fabricação de máquinas

Abstract

Occupational accidents in hydraulic presses are not so common in the machinery manufacturing industry, because common routine tasks are not performed as in serial production lines. These accidents commonly occur due to human error, lack of training of the operators, personal protective equipment not used, and especially due to the lack of fixed protection, mobile and/or electro-electronic. This study aimed to analyze the implementation of the new Regulatory Norm 12 (RN 12) for adjustment of hydraulic presses used in the metalworking industry for manufacturing materials such as steel, describing the risks of installing safety devices and protections present in the operation and solutions of operational improvements of the equipment, seeking solutions with lowest cost of investment and therefore the lowest impact on the operation. The solutions provided aim to fulfill the requirements of NR -12, revised in 2010, in order to preserve the health and physical integrity of workers causing lower impact on the production system.. A questionnaire based on NR-12 equipment in original condition and found others with the same questions to have proper equipment is applied. Thus our finding is also comparable with the old equipment.
