Code of practice for the design of protective measures for methane and carbon dioxide ground gases for new buildings

BS 8485:2007 受开发影响的地面气体的表征和补救用实施规则

This British Standard gives recommendations and describes methods for the investigation and assessment of the ground gases methane and carbon dioxide during new development of affected sites, and is not intended for the assessment of completed developments. It details a process that can be used to effectively demonstrate that risks posed by the potential presence of ground gas have been adequately considered and addressed. It presents the assessment and decision making stages in the form of a process flowchart, accompanying information and explanatory guidance and, where appropriate, references to other guidance and information. The standard does not consider ground gases other than methane and carbon dioxide. NOTE Other gases might require specific risk assessments and have to be considered separately.
