Overview
This standard is about commissioning gas systems, installations and components. It is for the industrial property parts of the non-residential downstream gas industry. It can apply to gas systems, installations and components for any type of fuel gas or combinations of fuel gas.
It includes carrying out pre-commissioning checks, identifying and resolving problems with gas systems, installations and components, liaising with people from other trades and handing over commissioned systems to users.
Any person carrying out this role must have site specific competence relevant to the level of risk.
This standard is for those who commission gas systems, installations or components in non-residential downstream, industrial properties.
Performance criteria
You must be able to:
You must be able to:
1. ensure that isolation is carried out by appropriate people before starting work
2. work in line with plans, safe systems of work and risk assessments
3. confirm gas systems, installations and components comply with industry standards
4. check and confirm that conditions within gas systems, installations and components meet safety requirements
5. carry out tightness testing and purging procedures which confirm the integrity of installed gas systems, installations and components at the appropriate pressure for the gas being supplied
6. confirm with input services personnel that the integrity and conditions in associated electricity, water, ventilation and flue/extraction systems will permit safe pre commissioning
7. select and use tools and equipment that are appropriate for commissioning activities
8. check and confirm that gas system operating pressures meet industry standards
9. check and confirm appliance gas operating pressures and heat inputs meet industry standards and manufacturers’ requirements
10. check combustion performance is within acceptable parameters
11. confirm combustion ventilation and flue/extraction systems’ performance against manufacturers’ and industry standard requirements using combustion and atmosphere analysis
12. confirm that gas systems, installations and components function and operate in accordance with safety and industry requirements and manufacturers’ instructions
13. liaise and cooperate with people from other trades at appropriate points in the work
14. verify that existing electrical, water, ventilation and flue/extraction systems, installations and components function and operate in accordance with safety requirements, industry requirements and manufacturers’ instructions
15. test and confirm that safety devices, gas shut off valves and interlocks are operating as per specification
16. resolve problems in accordance with approved procedures where checks and tests reveal gas appliance, gas system or components:
16.1. do not meet design requirements16.2. have defects or deficiencies16.3. cannot be restored to full performance17. reporting problems you cannot rectify to responsible person(s)18. liaise with responsible person(s) and others who will be affected by the work activities to minimise disruption to work19. comply with authorisation and verification processes that ensure correct working practices of other input services20. advise all people who are affected by work about any delays as soon as they occur21. report any delays in work schedules to job supervisors in line with agreed reporting procedures22. advise responsible person(s) of any unsafe situations, and actions required to remedy those situations, without delay23. complete required records and documentation for gas systems, installations and components24. ensure that isolation is lifted by appropriate people once work is completed25. interact with customers at appropriate times during your work26. instruct all responsible person(s) on the correct operation and ongoing procedures for plant and equipment and gas systems and provide them with copies of appliance literature
