Determination of Air Quality, Through the Cumulative Measurement of the Concentration of the Material Particles, in a Workshop for Making Metal Cast Parts

Abstract

Material particles represent a category of air pollutants, which greatly affect human health, and include in their composition, nitrates, sulphates, organic carbon dust and salt. The paper presents determinations of the air quality, from different sectors, of a metal casting workshop. The determinations were made during the technological process of production, as well as during when the workshop does not have a production activity. In all cases, was monitored the variation of material particles (PM) concentrations. The measurements were made with the help of the particle counter, Fluke 985, the results obtained, being compared with the legislation in force, regarding safety and health at work.
