SUMMARY
The Health and Safety Executive (HSE) provides advice on land use planning in the vicinity of major accident hazard sites and major accident hazard pipelines. As part of this process, HSE publish a guidance document, Failure Rate and Event Data, which contains failure rates for pieces of equipment found in major hazard chemical and process sites. The guidance document also contains information on event data such as aircraft crash and flooding, which are used when assessing the risks from such major hazard sites. An event such as an aircraft crash could lead to a release of a hazardous substance that could potentially harm people.
The aircraft crash rates were previously updated in 2009 using data up to 2006. This report updates the crash rates using data from 1990 to 2013. The methodology used to calculate the crash rates is also detailed. Uncertainty levels provide upper and lower bounds to the calculated crash rates to account for the uncertainty in the data that is used to derive the crash rates.
This Research 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 and do not necessarily reflect HSE policy.
