RR640 Third party major accident hazard pipeline (MAHP) infringement : A case study
Third party damage to underground services of all types continues to be a source of danger and financial loss to workers, members of the public, utility companies and contractors. When the underground service is a Major Accident Hazard Pipeline (MAHP) such as a high-pressure gas main or a petrochemical pipeline then the consequences of a rupture can be devastating to people and the environment.
The Health and Safety Executive’s (HSE’s) Gas and Pipeline Unit commissioned researchers at the Health and Safety Laboratory (HSL) to highlight the underlying issues that contributed to a third party MAHP infringement in February 2007. This report details the factors that contributed to that incident.
This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy.
