Dealing with gas escapes
|Publication Date:||1 January 2019|
This Standard sets out the requirements for dealing with gas escapes safely.
Primarily, this Standard deals with gas escapes from Natural Gas (NG) piped supplies and systems.
Note 1: In general, this Standard will not always be appropriate for escaped fuel that remains in a liquid phase, when further or alternative requirements may need to be applied. The Gas Safety (Management) Regulations (GS(M)R) lay down statutory requirements for dealing with reported NG escapes, which include escapes of carbon monoxide (CO). This Standard does not deal with the technical issues involved with reported CO "incidents", nor do the non-technical sections mention CO. However, the principles outlined in the non-technical sections apply to dealing with reported CO "incidents". Further information is provided in IGEM/GL/8.
Note 2: This Standard only deals with unignited gas escapes.
This Standard provides requirements for gas transporters (GTs), gas conveyors, Emergency Service Providers (ESPs), National Gas Emergency Service (NGES), shippers, suppliers and information for the likes of local authorities, plant operators, utilities and emergency services on the responsibility, methods and personnel involved in dealing with a gas escape. Particular attention is drawn to the requirement for competency outlined in Sub-Section 4.6.
This Standard covers the requirements to take action from the identification of a gas escape to make the situation safe along with appropriate notification to the relevant parties including the HSE.
All pressures are gauge pressures unless otherwise stated.
