HyDeploy2 Technical Services Report: Downstream Gas Standards Review

Abstract

The application of appropriate procedures in the downstream gas industry (defined as any works downstream of the emergency control value) is critical in protecting consumers of gas, both domestic and commercial. The two primary standard setting bodies for the downstream gas industry are the British Standard Institution (BSI) and the Institution of Gas Engineers and Managers (IGEM). To ensure only competent engineers carry out works on a gas installation, all gas businesses or selfemployed persons must become a member of Gas Safe Register, as stipulated by the Gas Safety (Installation and Use) Regulations 1998 1 and each gas operative shall be included on the register and hold a valid license card that covers the areas of gas work they undertake. Membership of the Gas Safe Register is contingent upon demonstration of competency, the recognised competency assessments are based on the relevant BSI and IGEM standards. Therefore, the primary source of a gas operative’s competency to work on natural gas installations are the associated BSI and IGEM natural gas downstream standards.
Investigation was undertaken to understand the potential implications of introducing 20 mol% hydrogen (H2) within natural gas supplies on the ability of gas operatives to competently carry out works. This investigation took the form of identifying all BSI and IGEM standards that could be applied on natural gas installations and reviewing them within the context of the known effects of introducing a 20 mol% H2 blend. Following review, a series of technical questions were generated and responded to by the Health and Safety Executive Science Division. The responses provided were then reviewed and if considered necessary challenged to provide further information. The procedural review was led by Blue Flame Associates, a body deemed sufficiently competent in downstream standards, training, certification and investigation. The report was subsequently reviewed by industry and feedback received. The industry comments were reviewed by the Project Team, and where considered necessary the report was updated.
