| Temporary edge protection systems (TEPS) used as a protection against falls from a height are an effective solution. These systems eliminate the risk at source, preventing the fall and avoiding the possibility of safetying injuries when a worker hits another kind of system that only limits the fall high. Previous publications show that the appropriate use of TEPS prevents a significant number of accidents and falls from a height. There are some studies that analyze the behavior of wooden TEPS under static and dynamic load. One of the main function of the TEPS is to avoid the fall of workers that stable and hit them. This is a dynamic action and is applied as an impact to the TEPS. There are studies in which dynamic loads are specified to simulate this action. These loads imitate the crash of a worker against a TEPS through an impact with a particular amount of energy. The test method of the I?Institut Nacional de Recherche et de Sécurité specifies an impact of a body of 80kg of weight hitting with a speed of 2m/s (E=120J). Other documents set an impact of a body of 90kg of weight hitting with a speed of 2m/s (E=180J). Some regulations that govern the use of TEPS [12-19] establish geometrical and mechanical requirements. Geometrical requirements lay down the dimensions of the TEPS so that workers and potential objects do not fall from a height. Mechanical requirements establish a minimum strength and máximum displacements depending on the load applied. The objective of establishing a limitation of the deflection is based on preventing the worker from tipping over the TEPS and falling over the edge. In this work, TEPS response to static and dynamic action has been compared. Static load has been applied according to the European regulation. Whereas the dynamic action has been applied through an impact of 180J of energy (figure 2). The results show that systems that reach the requirement of the European regulation are able to absorb the impact of 180J of energy. | |
