Safety barriers provide containment for vehicles without significant deflection or deformation under impact.
BS 6579-7 discusses safety fences and barriers for highways. BS 6579-7 is the seventh part of the BS 6579 multi-series, and specifies requirements for the components to be used in the construction of the untensioned corrugated beam (UCB) type of safety fence.
Note: The erection of the assembled fence is outside the scope of BS 6579-7.
BS 6579-7 on UCB safety fences and barriers for highways are 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 bridge parapet can be assured without impairing the overall protection afforded to the users of the highway. These factors include the choice of intermediate posts to suit the ground conditions and the erection and maintenance of the fence.
BS 6579-7 walks you through the components, tolerances, protective finish, and marking of safety fences and barriers for highways.
BS 6579-7 guidelines help you to mitigate risks related to vehicle accidents and also help you to safeguard personnel working on site.
