Elaboración de Procedimientos de Trabajo Seguro (PTS) para las áreas procesadoras de material vial de la Constructora COVIPAL Cía. Ltda.

Abstract

The objective of this technical project was the elaboration of safe work procedures (SWP) for the activities carried out in the road material processing areas in the Cerro Negro camp of the construction company COVIPAL Cía. Ltda. to prevent accidents and occupational diseases. The presence of hazards was evidenced in these areas, which were evaluated using the INSHT and NTP 330 methodologies to determine the level of risk present qualitatively and quantitatively, respectively. The information was obtained through direct observation, application of questionnaires, open interviews and technical and legal literature review. Initially, 184 risks were identified and evaluated applying the INSHT methodology, of which 45 were categorized as moderate and important, so they were subjected to a second evaluation using the NTP 330 methodology. The mechanical, physical and chemical risks with intervention level I were identified, representing 31% (14 factors); and the ergonomic risks were evaluated with a high level corresponding to 4% (2 factors). A total of 16 significant risk factors were obtained, such as: people falling from different levels, being run over or hit by vehicles, noise, exposure to dust, forced postures and physical overexertion. The activities that present the aforementioned risk factors required control measures because they can cause considerable harm to workers, so a PTS was drawn up, which is a safety manual that will be used to standardize activities. These provide sufficient information for the correct execution of activities and compliance with the proper use of PPE (personal protective equipment) as required by the work.
