Alarms, Accidents, and Unintended Consequences

Presentation Overview

In the 1990s, new projects and plant expansions began incorporating computerized control technology, such as SCADA and DCS systems. This was driven by advantages in control, cost, reliability, and process analytics. However, it took a string of expensive accidents before people understood that the new types of alarm systems could be a serious problem. Even after that realization, many more accidents related to poorly performing alarm systems have continued to occur.

In this talk, several such accidents will be reviewed, highlighting how the alarm systems were found to be contributing factors. Issues include malfunctioning, misconfigured, and improperly suppressed alarms. In some cases, continuously high alarm rates and large alarm floods interfered with the operator’s ability to resolve the abnormal situation. Solutions to the alarm issues found will be identified.
