Gas Protection Verification Accreditation Scheme
Glossary of common terms used in the management of land contamination, published on the Planning Portal, defines the Gas Protection Verification Accreditation Scheme (GPVS) as: ‘…a scheme that seeks to raise standards in membrane inspection, verification and reporting and provide all stakeholders involved in land contamination management with confidence that risks associated with ground gases have been adequately managed.’
It is a specialised accreditation framework designed to ensure high standards in the verification of gas protection measures installed at construction sites. It is particularly relevant to projects where ground gases (such as methane, carbon dioxide, radon, or hydrogen sulfide) pose a potential risk to human health or buildings. Ground gases can arise from sources such as contaminated land, landfills, or naturally occurring conditions.
The scheme ensures that professionals involved in the verification of gas protection systems are competent, trained, and follow best practices. It aims to reduce the risks associated with improper installation or inadequate verification of gas protection measures.
GVPAS accredits individuals and organisations that have demonstrated expertise in assessing and verifying gas protection measures, ensuring compliance with relevant standards and regulations.
The scheme aligns with standards such as BS 8485, which provides a framework for designing and implementing gas protection in buildings. It emphasises compliance with CIRIA C735, which sets out guidance for the verification of ground gas protection systems.
he scheme enhances safety by reducing the likelihood of gas ingress into buildings. It provides assurance to developers, regulators, and stakeholders that gas protection measures meet the required standards and minimises long-term liabilities and potential remediation costs due to poorly executed gas protection.
Professionals such as environmental consultants, engineers, and contractors with relevant experience in ground gas risk management can apply for accreditation. Applicants typically undergo training, assessments, and must demonstrate practical knowledge of gas protection systems.
