Análise preliminar de riscos aplicada em serviços de sondagem rotativa no setor da mineração

Abstract

The rotary drilling technics are applied in the investigation of the rock material that forms Earths physical surface. Such investigation works as foment of information for engineering projects in the sectors of mining and civil construction. Therefore, it is expected that these drilling processes are exposed to the same risks that these sectors offers to their workers. The present monograph has as objective applying a Preliminary Risk Analysis (PRA) with the support of the checklist tool to identify the occupational risks that are intrinsic to this activity. As result of the application of the checklist and the PRA, the present monograph identified the occupational risks as: Crushing, mineral dust exposion, noise, material projection on the workers and others.The conclusion points that the risks of these activities can be avoided and mitigated by the use of collective protection equipment, individual protection equipment and training of the workers. The result of the Preliminary Risk Analysis and the application of the check-list allowed identifying and classifying nine risks of the activity, which five were classified as critical, two as serous and two as moderated. Most of these risks were considered severe with similar occurrence with other other activities from the mining sector with grave consequences toward the occurrence of work incidents.
