Setting up Safety Provision Levels

A safety provision describes the systems and processes that are put in place to prevent or mitigate a hazard scenario. Its level indicates the provision’s role: it can be the primary means of mitigating risk or it can support a primary level. The setting on the provision level determines whether or not provisions with the level can be linked to failure modes on SIF and HAZOP analyses.

Tip: A demand-reducing provision is put in place to reduce the demand placed on the asset, for example, by reducing flow or pressure.

To Set up a Safety Provision Level
