We recognised that in carrying out day-to-day management of the strategic road network including routine maintenance works and emergency repairs, there was a real risk posed where overhead power lines cross the network. This represented a clear hazard to our roadworkers and emergency services attending incidents on the network.
We worked with our supply chain and local emergency services to identify mitigation of this risk, establishing the Overhead Cable Marker Posts. The marker post is manufactured from a highly durable polymer material, which can withstand vehicle impact.
It was designed with a highly visible yellow reflective material, with no maintenance requirements. The knock-down, spring-back properties ensure that the marker posts are passively safe under BS EN 12767, thereby not in themselves introducing an additional hazard onto the network.
The marker posts provide a number of benefits:
- Improved Roadworker Safety: By clearly identifying the locations where overhead power lines cross the highway, roadworkers carrying out routine maintenance or emergency repairs can easily see whether overhead power lines cross the area where work is being carried out, especially during hours of darkness.
- Improved Safety for the Emergency Services: When attending an incident on the network, the emergency services are required to act quickly to minimise impact and preserve life. The faster that potential hazards can be identified the more opportunity the emergency services have to be effective. The marker posts provide the emergency services with key, accurate information regarding potential hazards in the area of any incident.
