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.
