Safety barriers provide containment for vehicles without significant deflection or deformation under impact. BS 6579-5 discusses safety fences and barriers for highways.
BS 6579-5 is the fifth part of the BS 6579 multi-series and specifies the requirements for the components to be used in the construction of the open box beam type of safety fence. Requirements are given for the materials and dimensions of the components and for protective finishes. The erection of the assembled fence is outside the scope of BS 6579-5.
BS 6579-5 on open box beam safety barrier for highways is useful for:
Safety fences are intended to absorb some of the energy of impact and to redirect the errant vehicle.
The safety fences and barriers for ground mounting which are the subject of BS 6579 are for use in conjunction with parapets on bridges and other structures which are the subject of BS 6779.
There are various situations and various methods by which transition between a safety fence or safety barrier and a vehicle containment parapet can be assured without impairing the overall protection afforded to the users of the highway.
BS 6579-5 provides you with requirements for the materials and dimensions of the components and requirements for protective finishes. BS 6579-5 walks you through the details such as tolerances and marking of safety fences and barriers for highways.
BS 6579-5 guidelines help you to mitigate risks related to vehicle accidents and also help you to safeguard personnel working on site.
