Assessment of Workers' Occupational Exposure in The Context of Industrial Toxicology

Knowledge and assessment of occupational risks in every workplace is the main objective of the prevention of occupational illnesses. The ultimate goal of safety and health at work is to protect life, integrity and health of workers against the risks of accidents and professional diseases that may occur in the workplace. This paper approaches the measurement of workplace respirable dust and microclimate parameters at a Romanian branch of a multinational company, in order to analyse the results in terms of safety and health of workers. The means of investigating the studied objective involved knowledge of the working environment, choice of pollutants, sampling, analysis and interpretation of sampled materials, as well as equipment and working methods. The research started as a result of an employee complaining about headache, respiratory discomfort and nasal congestion. The most frequent noxae measuring takes place in a working environment with developed industrial activities generating physical and chemical agents. This paper investigated the presence of noxae in workplaces located in Open Space offices where the main activity is IT. These spaces are ventilated by an air conditioning system, windows are fixed and the floor is carpeted on the entire surface. Research has led to the fact that the measured noxae (dusts, microclimate) have exceeded the maximum permissible concentration required by national legislation, this being an unexpected out coming for the company manager. These concentrations may be due to staff traffic, high number of employees and lack of natural ventilation. Following the evaluation results, a number of technical and organizational measures, aimed at improving the workplace atmosphere, was recommended.
