ABSTRACT

This article is dedicated to the prevention of electric shock in the operation of public or private electrical installations. The risks incurred are direct contacts with bare live conductive parts in normal operation and indirect contacts with metallic parts put under voltage in the occasion of incidents. The risks resulting from an electrical arc must be also considered. Operation of public or private electrical installation standards define the means to be implemented in order to ensure the protection of personnel against such electrical risks.

Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

 INTRODUCTION

Articles [D 5 101] , [D 5 102] and [D 5 103], each in their own part, develop ways of understanding, analyzing and controlling electrical risk.

The first article [D 5 101] presents accident statistics to date and the fundamentals of electric shock and electric current passing through the human body.

The second article [D 5 102] sets out the rules for the construction and installation of electrical works and installations.

This article describes the operation of electrical structures and installations, i.e. all construction, maintenance, repair and dismantling operations, as well as fire prevention in these facilities.

The protection of personnel during construction, maintenance, repair and dismantling operations is now governed by European and French rules that employers must scrupulously respect. These are simple, common-sense rules that require everyone, at all times, to appreciate and assess the electrical risk at its true value, and to apply the rules set out in numerous publications. In addition to training, the employer is obliged to issue the appropriate authorizations for the operations to be carried out, as soon as there is an electrical risk.

This article presents the operating modes and procedures used in Europe, i.e. de-energized work, which offers the best safety since there is no risk of electric shock, work in the vicinity where protective measures enable work to be carried out in a safe area, and finally energized work where the permanent presence of voltage is managed by rigorous personnel protection...
