Higiene ocupacional: gases e vapores

Abstract

The theme of this monograph is the link between occupational hygiene and chemical agents of the gases and vapors type in the workplace, in order to explain how occupational hygiene can anticipate, recognize, evaluate and control such agents. As a theoretical academic paper, the methods used were the research through books, monographs, theses, scientific articles of the area and specially was based on the regulatory norms of the legislation that embrace such chemical agents. The gases and vapors include different classifications about the chemical and physiological aspects, however, because they have similar behavior in the air, in the occupational hygiene, they are studied together, using sampling methodology and laboratory analysis that are often similar. Because they are highly dangerous, gases and vapors must be characterized and quantified in a safe and technical way in the work environment, using as reference the legal requirements applicable in Brazil and in international legislation, existing efficient technologies for their characterization and quantification.
