Abstract
According to EN 13374, type C temporary edge protection systems are the set of
components designed to protect people from falling to a lower level, and to
restrain material. This system may incorporate a safety net attached to a bracket
structure so that it may be used vertically. This document analyses such
fundamental aspects as their design and the solution to the problem posed by the
brackets or hard points which can cause injury to the victim of an accident.
We have therefore studied the phenomenon through a variety of numerical
models using ANSYS finite element software, and we have reached useful
conclusions such as the required geometrical shape, the cross section of the
profiles, and the impact factors suffered by accident victims. We are therefore
able to make some general points with regard to the regulatory text.
Keywords: rail, safety, net, fall, impact, stiffness, EN13374.
1 Introduction
If we consider the everyday activities of human beings at work, the construction
industry has produced and continues to produce the most serious accidents.
According to Spanish Labour Ministry statistics, if we average out the last
5 years, only taking falls to a different level into account, there are 2,042 serious
accidents and 114 mortal accidents every year, which equates to 26.74% of the
total number of serious accidents and 13.47% of the total number of mortal
accidents, respectively.
Safety handrails or temporary edge protection systems are used in
construction work, primarily to prevent persons and objects falling to a lower
level from rooftops, edges, staircases and other areas where protection is
required.
According to EN 13374:2004 [1], three types of handrails exist, A, B and C,
depending on the angle of the working surface and the height of the drop. Type
