(32cv) Barrier Management in Preventing Process Safety Incident

Barrier definition is a risk control that seeks to prevent unintended events from occurring, or prevent escalation of events into incidents with harmful consequences.

The IOGP-544 has illustrated the importance for the hardware barriers and human barriers for preventing or mitigating the consequences of any major hazardous materials release.

Hardware barriers Primary containment, process equipment and engineered systems designed and managed to prevent LOPC and other types of asset integrity or process safety events and mitigate any potential consequences of such events. These are checked and maintained by people (in critical activity/tasks).

Human barriers that rely on the actions of people capable of carrying out activities designed to prevent LOPC and other types of asset integrity or process safety events and mitigate any potential consequences of such events.

Bowtie model is a risk diagram showing how various threats can lead to a loss of control of a hazard and allow this unsafe condition to develop into a number of undesired consequences. The diagram can also show all the barriers and degradation controls deployed.

The bowtie case Study will reflect the importance of safety critical elements and activities and how they will be used to prevent or mitigate the consequences of any hazardous releases.
