Introduction to the assessment and management of ground gases and vapours

EPG logoIn recent years there have been significant developments in our understanding of the risks posed by ground gases (eg methane and carbon dioxide) and organic vapours that can impact on redevelopment projects.  This has resulted in a plethora of new guidance relating to the investigation, assessment, remediation and verification of gas-affected land.

LQM have partnered with Steve Wilson and EPG ltd, authors of several of the new guidance documents, to develop this introductory course, which is designed for delegates of all abilities; for beginners to those with lots of experience of sites impacted by ground gases (eg methane and carbon dioxide) and organic vapours.  The course is intended to provide both regulators and consultants the opportunity to gain a good grounding in the requirements of the latest British Standards and industry guidance relating to the investigation, assessment and management of potential risks posed by ground gases and vapours both under redevelopment and Part 2A regimes.

This course offers delegates the opportunity to learn from leading industry experts EPG ltd how to assess and manage the risks posed by ground gases and vapours.  The course will:

  • demonstrate the real risks posed by these hazards;
  • identify the classic sources and environmental behaviour of such contaminants;
  • outline the issues surrounding radon gas;
  • describe current methods for the investigation and measurement of gas and vapour hazards;
  • discuss the risk assessment methods;
  • present an overview of the management options available and teh design considerations;
  • describe the verification requirements.

By the end of the course you should be better able to understand:

  • the importance of gases and vapours in ensuring safe development;
  • the types of sites where these hazards may be present;
  • the basics of how these hazards can be investigated and characterised, and the considerations neccesary to design an adequate siet investigation;
  • current approaches to assessing the risks posed by ground gases;
  • the management options available where gases and vapours pose unacceptabel risks, and the verification procedures needed to ensure that adequate protection has been acheived.

All delegates will be issued with a Certificate of Attendance – which should be retained and used to provide evidence of CPD activity when required by employers or professional bodies.

The courses will be of relevance to:

  • Regulatory and local authority staff involved with contaminated land issues
  • Consultants
  • Problem holders and developers needing a more indepth understanding of contaminated land issues
  • Anyone producing contaminated land reports
  • Anyone reviewing third party reports
