Abstract

Methane and the gases often found with it can cause many problems during construction operations such as tunnelling and building in the vicinity of landfill sites. At whatever stage of construction process, from initial investigation to the operation of the completed works, if there is reason to suspect the presence of these gases, it will be necessary to be sure of safety. This report describes the methods and techniques that are available for the detection of these gases, for sampling them and for taking measurements relevant to mitigating the problems the gases pose. While centred on methane and landfill gas, the report also covers carbon dioxide and other hazardous gases. Within the context of safe working, there is comprehensive guidance on detecting gas, identifying the source, measuring and sampling different gases, and on the interpretation of the results. Factors which affect the investigation of gas, e.g. meteorological conditions, gas in groundwater, are discussed. The use of monitoring systems on a site and within buildings is described.
