Higiene ocupacional: aerodispersóides tipo poeiras silicosas

Abstract

The topic talk about the connection between Occupational Hygiene and the chemical agents of the type aero dispersed with focus in the silica dust in order to analyze how the occupational hygiene can anticipate, recognize, evaluate and control those agents. As a theoretical work, the methods used was researches in books, undergraduate thesis, thesis and articles. The chemical agents studied are silica dust, which can develop diseases and even lead the worker to death, according to the concentration, time of exposure, characteristics of the agent and personal susceptibility. The silica dust must be characterized and quantified technically and safely in the work place, using as a reference the legal requirement applied in Brazil and in the internationals agencies, with efficient technologies to characterize and quantify those substances. Measures must be taken to control this kind of dust in the environmental or in the human context, to guarantee the salubrity of the work place and the health of the employee.
