Links Resources

On the RAMPage is a new section, begun in mid-2000. It is intended to be a collection of resources on Reliability, Availability, and Maintainability- RAM - plus Safety. We also offer a several files of RAM data which can be downloaded.

Reliability

Human Reliability

ility Engineering does not specialise in human reliability; those interested in this subject should refer to Human Reliability Associates.

WARNINGS

1. All the download files on this page have been checked for viruses at the time they were created. However, ility Engineering can not guarantee that they have not become infected since that time. Users are strongly advised to check the files themselves before using them.
2. ility Engineering offers the contents of these files in good faith. However, ility Engineering will not be held responsible for any damage, however caused, by the use of these files by any individual.

Failure Rates

This is a zipped Microsoft Excel file of failure rate data for process equipment. The data are taken from a variety of published sources, all of which are referenced in the text. All the data assume the exponential distribution: i.e. failure rates do not change with time. A more comprehensive version of the file, including failure rates which are a function of time, is available from ility Engineering for a small fee. Click here to download.

PES Checklists

The UK Health and Safety Executive (HSE) used to publish a set of guidelines to the safe use of Programmable Electronic Systems (PES). These guidelines have now been superseded by IEC 61508. The original HSE guidelines contained a useful set of checklists which are largely unaffected by the requirements of IEC 61508 and are still issued as part of the material for the MSc degree in Process Safety and Loss Prevention at the University of Sheffield, a degree which is sponsored by both HSE and IChemE. As a service, we happily make these checklists freely available in the form of a zipped Microsoft Excel spreadsheet. Where appropriate, clauses in the checklists have been given explanatory comments. It is assumed throughout that the user is familiar with programmable control systems, the original PES Guidelines, and IEC 61508. Click here to download.
