Safety measures

Primary and secondary safety measures

With our risk matrix used as part of the hazard assessment process we classify potential risks according to their impact and estimated frequency in existing plants. Various risk classes and appropriate measures are derived from this matrix.
When planning a new plant, we investigate in our EHS reviews to what extent the risks identified can be avoided for example by using other substances, reactions or reaction conditions.

Safety measures need to be taken to control the possible remaining risks. Here, we differentiate between primary and secondary safety measures.

Primary safety measures prevent further consequences such as the release of substances in the event of a plant malfunction. To this end, equipment is installed to shut down the plant automatically, for example. The focus lies on these primary safety measures.

This safety strategy is backed up by secondary safety measures designed to ensure that effects are minimized in the event of an incident. These include protective walls, retention systems and fire fighting measures. If, despite all preventive measures, an incident has occurred, these safety measures ensure that the impacts are restricted to a manageable level.

Periodic audits are carried out at locations and plants to check compliance of our safety standards.
