RESUMO

Significant amounts of particulate matter, also called aerosols, are generated in many steps of mining and depending on its chemical and physical characteristics they are important agents that causes occupational diseases, named pneumoconioses. In order to protect the workers of this environment, some controls can be adopted. Among them, the most common control is the use of approved respirators. In this work is presented a critical analysis of particulate respirators selection procedures that are established at Respiratory Protection Program document and indicated the adoption of other important technical criteria for mining workers. Through the national and international bibliographic information, current regulations, data collection in mining industries and author professional expertise it was possible creating a mining workplace overview related to the presence of particulate matter, analyzing the respirator selection logic considering the Brazilian legal requirements and identifying the most common respirators applied at mining workplace. As a result of this work it was possible to discuss about the respiratory protection level that Brazilian mining workers are subjected and to suggest the use of respirators in some exposure situation.
