Values of the ULS for the TEPS prototype.

This study assessed an innovative temporary edge protection system (TEPS) designed and developed to improve the ergonomics, health and safety at trench works in the construction industry, which ranks as one of the most hazardous worldwide. A wooden prototype of this innovative TEPS was built, and its mechanical resistance was compared to a conventional one. Thereafter, field tests were carried out to evaluate the efficacy of this pioneering TEPS. Both in analytical studies and field tests, the mechanical resistance to static loads of the TEPS complied with EU standards, and outperformed the conventional TEPS. The novel TEPS is effective as fall protection for different trench shoring systems and in buildings without edge protection systems. Moreover, this novel lightweight TEPS is easy to transport, with simple and safe on-site installation.
