  1. A DNO’s perspective on G55/2 Alan Daley (Tree Programme Manager)

  2. Overview of G55/2 The purpose of G55/2 is to provide a common basis for safe working practices for DNO tree contract work in Proximity to any Distribution Network Operator’s equipment. The tree and vegetation industry has undertaken a big step change in their safety culture since the publication of G55/1. G55/2 now reflects this change

  3. The main difference between G55/1 and G55/2 involves the categories of tree work and the procedures to control risk, and it now addresses DNO work specifically Previously, there were three categories. There are now four categories: A, B, C and D, which allow arborists to work up to the safety distances

  4. DNO’s perspective • Safety – • We are now asking arborists to work closer to our network than ever before. • All arborists are being retrained to the new NPTC standards and procedures. • Central Networks has in certain areas decided to apply more stringent methods of work than those recommended by G55/2. • These are being briefed out by Central Networks.

  5. DNO’s perspective. • Helps to speed up compliance with legislation (ESQCR) • Reduce customer inquires and complaints • Financial benefits – • Reduced network interruptions • Able to cut more live spans • Reduced number of tree related incidents • Less CI and CMLs incurred • Safer and more reliable network for our customers

  6. Summary • There are concerns regarding safety- working closer to the network • These are been managed by risk assessment, training, auditing and where necessary DNO’s restrictions • There are compliance with legislation benefits which in turn brings customer satisfaction • There are financial savings which ultimately benefit the DNO, customers and stakeholders

  7. A DNO’s perspective on the revised UA units David McAlinden (Tree Compliance Manager)

  8. So, in summary • CN’s tree contractors are currently undergoing technical updates and assessment to the revised UA units • When this process is complete, CN will brief its tree • contractors to G55/2 and its locally required “amendments” • After briefing, CN tree contractors will be working to G55/2
