Joint materials by electro fusion processes on water networks

Overview

This Standard is about jointing materials by electro-fusion processes.  Electro-fusion processes may be carried out in all weather conditions using non-automatic and automatic machines and on parent materials with the same SDR rating, and polymer type.

Jointing materials by electro fusion includes providing weather protection, checking joint preparation, equipment and consumables, monitoring machinery, making electro-fusion joints to specification, shutting down equipment and dealing with waste.

This Standard is for anyone in water network construction who carries out electro fusion jointing.

 

Performance Criteria

You must be able to:

  1. work in line with health, safety and environmental regulations, guidelines and procedures at all times
  2. carry out and review site specific risk assessments in accordance with company procedures
  3. select and wear designated personal protective equipment
  4. check any circumstances where job instructions or procedures appear incorrect with appropriate people
  5. check that jointing and related equipment and consumables are as specified and fit for purpose
  6. provide adequate weather protection in line with organisational procedures for the duration of jointing cycles
  7. using lifting equipment when required in line with current regulations
  8. report any damage or defects to tools, equipment or materials to appropriate people without delay
  9. use appropriate electro-fusion jointing techniques to produce joints of the required quality
  10. joint materials by electro-fusion processes in line with approved procedures and practices and statutory and regulatory requirements
  11. confirm compliance of completed joints with specified standards and specified dimensional accuracy
  12. shut down equipment to a safe condition on completion of jointing activities
  13. deal with excess and waste materials and temporary attachments without delay in line with approved and agreed procedures
  14. record and store jointing data and information in organisational information systems
  15. resolve problems that are within your area of responsibility in line with organisational procedures
  16. refer problems you cannot resolve to appropriate people using approved procedures
