Technical - Legislation Series Standards

These standards give advice on Legislation affecting the Gas Industry

These Standards are intended to assist in compliance with legislation, primarily aspects of the Gas Safety (Management) Regulations (IGE/GL/1, 2, 4, 5, 6 and 8), but also the Gas Safety (Installation and Use) Regulations and the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (IGE/GL/8).

  • IGE/GL/1 - Planning distribution systems

    • provides guidance on the planning of distribution systems so that, as far as possible, continuity of gas supply is maintained to consumers on the system, and at sufficient pressure that their appliances continue to operate at all times unless load shedding has been initiated.
    • the relevant parts of this Guidance may be cited in the gas transporter's (GT's) safety case, but the Health and Safety Executive (HSE) will need to satisfy itself that the parts are appropriate and have been properly applied in each case.
    • contains advice on the planning and design of Natural Gas distribution systems (hereafter referred to as "systems") of MOP not exceeding 16 bar. The Guidance does not encompass the availability of gas entering the system. Its purpose is to ensure that there is sufficient transportation capacity.
    • includes the arrangements and agreements required between different GTs and Network owners at system boundaries, to ensure the continuity of gas flow.

  • IGE/GL/2 - Planning of transmission and storage systems

    This Standard is designed to provide guidance on the planning of Natural Gas distribution systems so that continuity of gas supply is maintained to consumers at sufficient pressure.

    • provides guidance on the planning of transmission and distribution systems so that, as far as possible, continuity of gas supply is maintained to consumers so that, as far as possible, continuity of gas supply is maintained to consumers on the system, and at sufficient pressure that their appliances continue to operate at all times unless load shedding has been initiated.
    • the relevant parts of this Guidance may be cited in the gas transporter's (GT's) safety case, but the Health and Safety Executive (HSE) will need to satisfy itself that the parts are appropriate and have been properly applied in each case.
    • contains advice on the planning and design of Natural Gas systems and any associated storage (hereafter referred to as "systems") of MOP exceeding 16 bar. The Guidance does not encompass the availability of gas entering the system. Its purpose is to ensure that there is sufficient transportation capacity.
    • includes the arrangements and agreements required between different GTs and Network owners at system boundaries, to ensure the continuity of gas flow.

  • IGEM/GL/4 - Gas system assets – risk management

    This standard specifies requirements for risk management of assets associated with gas systems.

    • specifies requirements for risk management of assets associated with gas systems. In GB, this would mean systems that come within the scope of one or more of:
      • Construction (Design and Management) Regulations (CDM)
      • Gas Safety (Installation and Use) Regulations (GS(I&U)R)
      • Gas Safety (Management) Regulations (GS(M)R)
      • Management of Health and Safety at Work Regulations (MHSWR)
      • Pipelines Safety Regulations (PSR)
      • Pressure Systems Safety Regulations (PSSR)
    • features effective health and safety management which are indistinguishable from the sound management practices advocated by proponents of quality and business excellence. Indeed, commercially successful companies often also excel at health and safety management, precisely because they bring efficient business expertise to bear on health and safety as on all other aspects of their operations
    • specifies a framework for risk management of assets associated with gas systems. The specified framework covers all activities, including design, installation, operation, maintenance, management and providing an emergency service on the assets associated with gas systems.

  • IGEM/GL/5 - Managing new works, modifications and repairs

    This UK Standard IGEM/GL/5 Edition 3 for managing new works, modifications and repairs updates and replaces IGE/GL/5 Edition 2 which is now obsolete.

    This Standard is for the documented procedures for managing new works, modifications or repairs in compliance with UK Regulations. This Standard also applies to other plant and systems, for example control systems and software.

    Overall this Standard is for the management and control of new works, modifications and repairs to assets associated with the supply of fuel gas such as Natural Gas (NG), Bio-gas (including biomethane), Liquefied Natural Gas (LNG), Liquefied Petroleum Gas (LPG) and LPG/Air. This Standard applies to assets within the scope of Gas Safety (Management) Regulations, Pipelines Safety Regulations, Dangerous Substances and Explosive Atmospheres Regulations, Electricity at Work Regulations, the Control of Major Accident Hazard Regulations and Pressure System Safety Regulations. This Standard encompasses all disciplines and applies to in-house, outsourced and third party activities.

  • IGEM/GL/6 - Permitry for the safe flow of gas

    • covers permitry for the safe flow of gas, for both the upstream and downstream pipelines intended to convey primarily Natural Gas and it includes the following types of permits:
      • Non-Routine Operation (NRO)
      • Routine Operation (RO)
      • Permits to work (PTW)
      • Other ancillary permitry for work procedures and maintenance.
    • is applicable to gases other than Natural Gas.
    • provides Gas Industry specific guidance for the application of HSG 250.

  • IGE/GL/8 - Reporting and investigating gas incidents

    This Guidance is for gas transporters, gas suppliers, gas operatives and others and covers reporting and investigating incidents and dangerous occurrences associated with the supply and use of fuel gases.

    • supports certain requirements under the Gas Safety (Installation and Use) Regulations (GS(I&U)R)
    • is for gas transporters (GTs), gas suppliers, gas operatives and others and covers reporting and investigating incidents and dangerous occurrences (including gas fittings found to be dangerous) associated directly with the supply and use of fuel gases.
    • intends to also provide appropriate guidance for Liquefied Petroleum Gas (LPG) which is not covered by, for example, GS(M)R. However, for most issues, the guidance (as opposed to the legislation) is the same for LPG as for Natural Gas. Where there is a difference, LPG is mentioned specifically.
    • covers the reporting and investigation of onshore incidents and dangerous occurrences associated directly with the supply and use of gas. this would include incidents:
      • on gas supply networks, for example loss of gas or ingress of water
      • on gas storage sites, for example loss of gas
      • on any as pipework involving explosions that cause damage to property
      • involving carbon monoxide (CO) poisoning arising from the burning of gas.

  • IGE/GL/9 - Natural gas supply in an emergency

    IGE/GL/9 aims to give simple advice to Natural Gas consumers on the consequences of the loss of their gas supply, their legal obligations, and technical requirements to ensure continued safe operation of consumers' plant.

    • supplies Natural Gas consumers with simple advice in the event of a Natural Gas Supply Emergency. It advises users of the following:
      • consequences of the loss of gas supply
      • legal obligations
      • technical requirements to ensure safe operation consumers' plant.
