RGII Domestic Gas Safety study guide
RGII Domestic Gas Safety · Work through your exam, one topic at a time.
The RGII Domestic Gas Safety assessment is the competence check that sits behind registration with the Register of Gas Installers of Ireland (RGII) for work on domestic natural gas installations. It is aimed at craftspersons - typically qualified plumbers, heating engineers or pipefitters - who need to demonstrate that they can install, commission, service and make safe domestic gas appliances and associated pipework to Irish requirements. The RGII Domestic Gas Safety study guide has 8 sections and about 2,741 words.
01Legislation, Regulations and Standards (Gas Safety Framework)
This domain checks that you can place domestic gas work inside the Irish legal and regulatory framework: the Gas Act 1976 as amended, the Safety, Health and Welfare at Work Act 2005, the Building Regulations (especially Part J), CRU gas safety policy, the RGII registration regime and I.S. Questions often ask who may do gas work, which document proves compliance, and which standard overrides another.
