This guidance is a practical aid for designers and site workers on what
to eliminate, avoid and consider when working on the Openreach
network on your site.
The advice is not exhaustive so speak to your Field Based
Co-Ordinator (FBC) if you need further information.
Red lists
Hazardous procedures, products and processes that should be eliminated
from the project where possible.
Distribution point (DP) location
• Placing DPs into voids or other enclosed spaces with inadequate ventilation
• Placing DPs adjacent to, or above, any fragile surface
• Placing DPs directly above, or adjacent to, water features / courses etc
• Locating DP at greater than 1.5 meters above nished oor level (without xed access
system incorporated into design)
Cabling routes and lead-ins
• Routing of cables where the cables are above head height within false ceiling systems
without a proper access system incorporated
• Routing of cables external to building requiring specialist access methods (scaffold,
mobile elevating work platform etc.)
• No internal ducting laid into Single Dwelling Units (SDUs)
Power systems
• Ensure all power installation meet relevant standards, and where DC supplies are planned
seek further advice about requirements for earthing of racks, power supply ratings etc. to
take account of future needs and growth
Aerial and antenna transmission / receiver systems
• Not mounted on building walls or other difcult to reach areas of a building
• Design of roof mounted services that require access (for maintenance and so on), without
provision for safe access (such as barriers) in particular access for aerials / antennas systems.
