Fundações por tubulão a ar comprimido: um estudo sobre o trabalho executado

Abstract

The work on foundations by compressed air pipes requires special care, with regard to the workers ' attention in relation to possible accidents that may occur during their work inside the tubule and, mainly, in relation to their health, a Since, for the execution of this type of foundation there is the need for the work environment to be subjected to pressures above the atmospheric (around 1 atm), that is, a hyperbaric environment. They were analyzed through the bibliographical study on the theme, the situations of execution and their observance of the safety norms related to this activity, as well as the discussion of their exception in the list of activities contained in the norm that deals with activities and dangerous operations. It can be concluded that the work carried out within these tubules is neglected in relation to the normative safety requirements-considering the usual prescriptions of work in civil construction-and salubriousness, both by the employees of the contractor of the work, and on the part, in general, of a company (subcontractor) contracted for the execution of the foundation by pneumatic tubules. The lack of a more specific occupational safety and health guideline for this type of activity and a greater practical observation of its execution in loco, contribute to the installation of an environment prone to the occurrence of occupational accidents, as well as to the increased incidence of occupational diseases caused by the high degree of unhealthy health related to this activity.
