Vehicle safety fences have to be tested against the European standard and, as with all standards, there are different levels for compliance. Therefore, it is up to the specifier to determine the containment level and for the supplier to offer the most economical solution.
Vehicle safety restraints tested in accordance with the standards are safe to use at the appropriate location but, in many instances, the factors that make them unsafe is the way that they are used by the engineers.
Can we therefore get away from unsubstantiated references to catapulted vans and 'a number of fatal accidents' (as if no one had ever been killed in an accident involving beam fences). Will the promoters of safety fences instead please put their efforts into ensuring that their product is used at suitable locations in the correct manner.
