De-commission gas systems, installations and components in commercial properties and leisure accommodation

This standard is about de-commissioning gas systems, installations and components.  This could apply to temporary or permanent decommissioning.   It is for the commercial property and leisure accommodation 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 checking systems are safe for de-commissioning, identifying and resolving problems with gas systems, installations and components, liaising with people from other trades and carrying out temporary or permanent de-commissioning.

This standard is for those who de-commission gas systems, installations or components in non-residential downstream, commercial properties or leisure accommodation.

1. work in line with plans, safe systems of work and risk assessments

2. check that conditions within the gas system will permit safe de- commissioning

3. confirm with input services personnel that the integrity and conditions in associated electricity, water, ventilation and flue/extraction systems will permit safe de-commissioning

4. select and use tools and equipment that are appropriate for de-commissioning activities

5. use designated safe isolation methods, tests, and procedures to de- commission gas systems, installations and components

6. verify that associated electricity, water, ventilation and flue/extraction systems and components have been de-commissioned and removed in line with safety requirements

7. ensure that temporarily and permanently de-commissioned appliances, systems, and components do not present safety hazards

8. remove and disconnect gas systems, installations and components in line with job requirements

9. remove, dispose of and recycle waste materials and system contents in line with safety and environmental requirements

10. liaise with responsible person(s) and other people who will be affected by the work to minimise disruption to work

11. comply with authorisation and verification processes that ensure correct working practices on other input services

12. liaise and cooperate with people from other trades at appropriate points in the work 

13. advise all people who are affected by work about any delays as soon as they occur

14. report any delays in work schedules to job supervisors in line with agreed reporting procedures

15. advise responsible person(s) of any unsafe situations, and actions required to remedy those situations, without delay

16. complete required records and documentation for de-commissioning

17. rectify any deficiencies in gas input services, reporting those you cannot rectify to appropriate person(s)

18. verify and report deficiencies in electricity, water, waste water, ventilation, flue/extraction and fresh air systems in line with procedures

6. methods of working which protect building décor, customer property and existing systems and components

7. care and maintenance requirements of tools and equipment, and checks for safe condition

8. tools, equipment, materials and components required for de- commissioning

9. how to secure and store tools, equipment, materials and components to meet safety requirements and minimise loss or wastage

10. potential hazards that could arise from all de-commissioning, activities and the checks to be carried out before work takes place
