-
Installation pipework.
Pipework with an open end, connected to a gas supply.
ID
Seal all open ends with an appropriate fitting.
-
Installation pipework.
Pipework and/or fittings of inappropriate material for purpose and liable to damage. For example, plastic water pipe or hose pipe.
ID
While this may not pose an immediate threat to life or property, there is a high risk of accidental damage occurring which could cause a serious incident.
-
Installation pipework.
In emergency situations where there is no access, restricted access, or no handle on the ECV.
ID
Advise the responsible person that access is required at all times to allow isolation of the gas supply in the event of an emergency situation. It is accepted that without access, the ECV cannot be turned off, but all the appliances must be turned off and reported immediately to the ESP.
-
Installation pipework.
In a non-emergency situation, where there is no access, restricted access, or no handle on the ECV.
AR
Advise the responsible person that access is required at all times to allow isolation of the gas supply in the event of an emergency situation. Report to the ESP.
-
Installation pipework.
"Let-by" of any ECV which forms part of the tightness test.
AR
For ECVs inform the Gas Emergency Contact Centre. Where there is a detectable smell of gas, this must be classified as a gas escape (ID)
-
Installation pipework. "Let-by" of any additional Emergency Control Valve, AECV, that forms part of a tightness test.
Maintain or replace AECV prior to undertaking tightness test. Where there is a detectable smell of gas, this must be classified as a gas escape (ID)
-
Installation pipework. No AECV provided at the point of entry into the property where there is no adequate access to ECV.
AR
-
Installation pipework. Pipework suitable for gas and/or gas type used in an inappropriate location and/or situation.
AR
For example, PE pipework incorrectly installed within a building, or PE pipework exposed above ground level without suitable protection.
-
Installation pipework. Pipework showing signs of corrosion or damage likely to affect safety.
AR
Pipework that is not suitably protected against corrosion and positioned where it may suffer damage from corrosion, but not showing any visible signs of corrosion and/or damage, would normally be classified as NCS.
-
Installation pipework. Pipework significantly undersized preventing the appliance from operating at the manufacturers intended minimum gas heat input rating or affecting the safe operation of any appliance.
AR
Undersized installations, which do not affect the safety of any appliance operation, or prevent any appliance(s) from operating at its minimum intended gas heat input rating, are normally classified as NCS.
If the undersized pipework affects the safe operation of any appliance e.g. combustion and/or flame stability, then escalate the classification to ID or AR as appropriate for the affected appliance(s).
-
Installation pipework. Gas pipework located within a cavity wall or void but not within purpose-designed duct in accordance with appropriate standards.
AR
Gas installation pipework (including fittings) located within a cavity wall, is considered to be at a higher risk than pipework passing through a non-sleeved cavity wall by the shortest route.
-
Installation pipework. Pipework passing through any walls (including cavity walls) which are not sleeved or appropriately sealed.
NCS
-
Installation pipework. Inadequately supported pipework
NCS
