Abstract: A safety protector for application on vertical posts (6) tied-down to the ground and that constitute corrugated sheet supports with safety rail barrier functions, establishing a separation between its lower edge and the ground, through which a person involved in an accident due to sliding over the asphalt may impact on the corresponding section of the vertical support post (6). The safety support is constituted by an extruded profile (1) that is assembled to be adapted as a cover on post (6), the latter having internal partitions (1) and re-thickened zones, as well as an internal sinuous profile to be adapted on corresponding post (6), externally providing impact areas for persons involved in accidents that reduces the violence and diminishes the impact force, efficiently damping the latter.
