HOW TO AVOID AN EXPLOSIVE SITUATION

Methane gas, in explosive concentrations, was detected in the 1980s in two major UK tunnels during their construction and operation. The gas is now more widely recognized as a hazard which may be encountered during the execution of underground projects by civil engineers, although the source of the gas and its manner of operation and movement is still debated. This paper reviews the detection, sampling and analysis of methane, the difficulties of source identification and the means of gas movement into, and in strata adjacent to, below ground civil engineering projects.
