Abstract: At present, it is striking that a large percentage of occupational accidents in the construction sector are still caused by falls from height. Therefore, curbing the severe personal, social and economic consequences of these events is not only a commitment but an obligation for all stakeholders in the construction sector. After a review of current fall protection systems on construction sites, the purpose of this study is to establish the preliminary requirements for the design, development and prototyping of a new system which can be used as an auxiliary means to prevent occupational accidents in the construction sector caused by fall hazards at height. Based on the design science research (DSR) methodology, this paper tests the capability of alternative materials (metals, plastics and composites) to withstand the loads required by the regulatory standard UNE-EN 13374:2013+A1:2019 and looks at the improvements they can offer. The results obtained enable new metals and composite materials to be put forward, based on their suitability to the parameters of the risks of falling from height, ensuring that the greatest number of potential situations are addressed. Then, the needs to be satisfied and requirements to be met are listed, prioritised and considered for new temporary edge protection systems (TEPS). Next, the attributes that increase user satisfaction and/or reduce user dissatisfaction are filtered by means of a Kano model, which is applied thanks to the responses of construction designers, coordinators and supervisors. Once these questions are solved, an analytic hierarchy process (AHP) is performed by a focus group, weighing the Kano contributions and ranking the materials to be selected for the preliminary design of innovative TEPS for construction works. After considering safety, ergonomics, adaptability, sustainability, efficiency, manufacturability and flexibility criteria, the basis for the design of a new temporary edge protection system is established.
