Abstract

Temporary electric installations occur in small, average and great construction-sites and many times for being of temporary nature are unsafe and precariously executed. The electricity, source of potential danger even in low tension, is responsible on significant part of the occupational accidents, directly by means of electrical shocks and burnings due the voltaic arcs or indirectly by means of injuries caused for machines, equipment and components, requiring therefore, special attention in order to prevent accidents. Through case study it is considered to verify the safety condition in a construction-site temporary electric installations in the NR 18 - Conditions and Environment of Work in Construction Industry regulations.
