Rede piso a piso e guarda-corpo: a percepção de risco na exposição a queda em altura dos trabalhadores da construção civil em obras residenciais no município de Salvador/BA

Abstract

This work aimed to evaluate the perception of risk in exposure to falls from heights of civil construction workers, among the Collective Protection Equipment (CPEs): floor-to-floor net and guardrail, in two different residential jobs in the city of Salvador, Bahia. Digital questionnaires were applied through the Google Forms platform to survey risk perceptions among EPCs in this 2 residential jobs . For the main active workers in this field, working directly with this equipments, the main topics covered were: feeling of security, exposure to the risk of falling, misapplication on installation and comfort of the materials. As for the general workers in construction, that do not work directly with this equipments different questions were asked, such as: crucial criteria to define the system, need for maintenance, cost and need for complementary protective measures. When interviewed in two different residential jobs and asked about which of the EPCs the workers felt most protected 95% said it was the floor-to floor netting on residential job “1” and 50% on residential job “2”. With regard to exposure to the risk of falling, 90% said it was the guardrail in residential job “1” and 87.5% in residential job “2”. In the interview with the general workers in construction, that do not work directly with this equipments, 100% of the interviewees stated that workers feel safer with the floor-to-floor network installed in both residential jobs. When the EPCs are compared to each other, from the perspective of workers that work directly and indirectly with this equipments, it can be concluded that the floor-to-floor network is a collective protection measure with less risk exposure, less installation deviation, innovative, reliable and safe.
