Developed by: Enginuity
Approved on: 28 Feb 2015

Overview

This standard identifies the competences you need to assist in the installation of emergency electrical power generation equipment, in accordance with approved procedures. You will be required to assist in the installation of a range of emergency electrical power generation equipment, such as turbine alternator sets, piston engine sets, and generators.

This standard does not involve maintenance/repair type activities, such as removal and replacement of existing equipment.

You will be required to use the appropriate tools and equipment throughout the installation activities, and to apply a range of installation methods and techniques to position, level and align the equipment, and to make connections to the required services. The installation activities will include making checks and adjustments, in line with your permitted authority, and assisting others to ensure that the installed equipment functions to the required specification.

Your responsibilities will require you to comply with organisational policy and procedures for the installation activities undertaken, and to report any problems with the activities, tools or equipment used that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You must ensure that all tools, equipment and materials used in the installation activities are removed from the work area on completion of the work, and that the relevant job/task documentation is completed accurately and legibly. You will be expected to work to instructions, alone or in conjunction with others, taking personal responsibility for your own actions, and for the quality and accuracy of the work that you carry out.

The installation activity may be carried out as a team effort, but you must demonstrate a significant personal contribution to the installation activities, in order to satisfy the requirements of the standard, and you must demonstrate competence in all the areas required by the standard.

Your underpinning knowledge will be sufficient to provide a sound basis for your work, and will enable you to adopt an informed approach to applying installation procedures to emergency power generation equipment. You will have an understanding of the equipment being installed, and its installation requirements, in adequate depth to provide a sound basis for carrying out the installation process safely and effectively.

You will understand the safety precautions required when carrying out the installation activities, especially those for ensuring the safe isolation of services. You will be required to demonstrate safe working practices throughout, and will understand your responsibility for taking the necessary safeguards to protect yourself and others in the workplace.

  17. methods of connecting equipment to service supplies (such as electrical, fluid power, compressed air, oil and fuel supplies)
  18. the basic principles of how the equipment functions, and its operating sequence
  19. why electrical bonding is critical, and why it must be both mechanically and electrically secure
  20. the procedure for the safe disposal of waste materials
  21. how to recognise installation defects (such as leaks, poor seals, misalignment, ineffective fasteners, foreign object damage or contamination)
  22. the importance of ensuring that the completed installation is free from dirt, swarf and foreign object damage, and of ensuring that any exposed components or pipe ends are correctly covered/protected
  23. the problems that can occur with the installation operations, and how these can be overcome
  24. the fault finding techniques to be used if the equipment fails to operate correctly
  25. the recording documentation to be completed for the activities undertaken

the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
