Alarms by definition are events that require an action and as such alarms are a pivotal mechanism for driving industrial operator actions. In a recent survey completed by Automation World, 52% of respondents said they do not perform an analysis of their alarm systems to identify its strengths and deficiencies. Below is a list of the top 10 most common problems with alarm handling that reach across various industries identified by our partner Solutions PT and a video with techniques for better Situational Awareness through Actionable Alarm Management.
Top 10 Common Issues with Alarm Handling
- Many alarm systems have been implemented without any proper guidance
- Many alarm systems either alarm everything or rely on default alarms
- There is often little visibility or reporting on how many alarms your operators are having to deal with

- Alarm flooding - too many alarms make it difficult to distinguish which need immediate action
- Too many levels of alarms make it hard to prioritise
- There is a tendency to think alarming is only important in more dangerous industries such as Oil and Gas when actually all industries can be affected by poor alarm management
- There is not always one person responsible for Alarm Management’
