Sistema de Linha de Vida para Trabalho em Altura em Construção Predial – Varal de Segurança: Estudo de Caso

Abstract

Like any other field, vertical civil construction presents dangers and risks in the work environment, which some are characteristic, such as the risk of falling. Working at heights is one of the main causes of death at construction sites, hence the need to implement safety procedures in the execution of the activities by all employees. The Safety Clothesline is a protection system that prevents falls from height implemented by the engineering team on the slabs in construction seeking for productivity and safety improvements for workers in the execution of edge activities, replacing the traditional safety line system. This is a case study carried out in a building construction in the city of Campo Grande and aims to analyze and compare the Safety Clothesline with the traditional protective system, in addition to evaluating the efficiency of this system. As a result, it was observed that there were considerable gains in productivity, mainly in the ascension of the safety line. The Safety Clothesline brought mobility to the safety line with the use of mobile clamps, and consequently the reduction of the fall factor, which is decisive for reducing the risk of falling, guaranteeing the physical integrity and worker health. The big disadvantage when comparing security methods is the high cost. It is concluded that, although the initial investment for the acquisition of the Safety Line is high compared to the conventional system, the gains in productivity and safety are considerable. Finally, the Safety Clothesline was an excellent acquisition, which should be replicated for the Group's other projects, already considering the improvements implemented so that workers can perform their tasks safely and with high quality.
