Steve Pate (NCE 25 July) is correct in highlighting a number of concerns in respect of the safety currently afforded to traffic management operatives by barriers on motorways.
However, I think his correspondence raises more fundamental concerns as to the methods of installing the advance signing rather than highlighting any particular 'design flaw' of concrete barrier compared with tensioned steel barrier.
No risk assessment can be justified that supports operatives crossing multiple high speed traffic lanes while carrying signs and frames. I believe current Health & Safety Executive and Highways Agency advice requires lane closures to be carried out under the protection of vehicles equipped with crash cushions.
The argument for using tensioned steel barriers to support this method of traffic management installation must therefore be flawed.
However, a possible solution might be to incorporate a socket in the top of the barrier so that a sign can be mounted and locked parallel to the barrier when not in use.
