TR30 Passive Safety is aimed at lighting designers as an aid to identify such locations and provide a risk assessment approach to each location.

The document has been produced by designers for designers, and cuts through much of the mystery shrouding the use of passively safe products, giving designers an easy-to-follow route from their initial design thoughts to the final selection of equipment in line with BS EN 12767 and BS EN 40.

Lighting designers now need to consider the use of passively safe products when -preparing any new scheme or indeed replacing existing equipment situated on the highway. With the introduction of BS EN 12767:2007 and Transport Research Laboratory (TRL)’s SL04/07 Use of Passively Safe Signposts and Lighting Columns, and the withdrawal of the Design Manual for Roads and Bridges (DMRB) TA 89/05, designers are required to consider all road speeds when proposing new or refurbishing existing lighting and signage schemes.

Previously under TD 89/05, structures only needed to be considered for passive safety where the road speed was 50 mph or greater, or on lower speed roads where safety barrier or supplementary restraining systems (SRS) protection would be inappropriate or difficult to install. This document aims to help the designer identify such locations and provide a risk assessment approach to each location.

The document has been produced by designers for designers, and cuts through much of the mystery shrouding the use of passively safe products, giving designers an easy-to-follow route from their initial design thoughts to the final selection of equipment in line with BS EN 12767 and BS EN 40. Whilst this document is an aid for the designer, it is not intended to be the definitive answer to every scenario.

Local authorities and clients alike should consider developing a full written policy/statement considering the implications of passive safety and setting out their own clear guidance. This policy should cover all elements of the highway and not just street lighting and signage. An example from Durham County Council is found in Section 7.
