• Alarm Management

     

    This 25 minute presentation looks at the alarms that are received in control rooms typically found in oil refineries, gas plants, chemical sites, power stations and similar.  These may be hard wired alarms to a fixed panel, but most nowadays will be computer based systems.

     

    These alarms should warn operators about something that requires their prompt attention.  Typically an equipment malfunction or control failure.  However, there are lots of problems with alarms in many control rooms, especially with newer computer based systems.

  • Causal Tree Analysis

    Causal Tree Analysis provides a means of analysing the critical human errors and technical failures that have contributed to an incident or accident in order to determine the root causes.  It is a graphical technique that is simple to perform and very flexible, allowing you to map out exactly what you think happened rather than being constrained to accident causation model.  The diagrams developed provide useful summaries to include in incident and accident reports that give people a good overview of the key issues.

  • Hierarchical Task Analysis (HTA)

    Hierarchical Task Analysis is an excellent method of capturing how tasks are performed in a systematic and structured fashion. It is a graphical technique that allows groups to work on the analysis together.  This is useful for identifying different practices and for developing a consensus on what constitutes best practice.

    Hierarchical Task Analysis is particularly useful when developing procedures, training plans and competency systems.  Also, being hierarchical it is particularly suited to new projects as it can be developed in conjunction with the design.

    This article titled Task Risk Management will give you a context in which HTA is particularly valuable. The following video clips should you how to carry out HTA in practice.
