Process Safety Management (PSM)

Distinction from the hazard profile

While the hazard profile of a chemical or petrochemical plant describes which material risks are present, process safety management describes the methodical approach used to systematically identify, assess and control these risks across the entire plant lifecycle. PSM is therefore not a substitute for industry-specific protection concepts, but the overarching management system that ensures their consistent implementation – from design through operation to decommissioning.

Core elements

Recognised PSM frameworks are typically structured into elements such as process knowledge management, hazard identification and risk analysis, management of change, operating procedures, asset integrity, contractor management, emergency planning, and incident investigation and auditing. It is essential that these elements operate as an interconnected system rather than in isolation, since major events in the process industry are regularly traced back to the simultaneous failure of several barriers.

Insurance relevance

For property and liability insurers, the maturity of an organisation’s process safety management is a significant, often underestimated factor in risk assessment, as it indicates the likelihood of major events in a way that a pure site survey cannot reveal. A documented, actively used PSM system – for example evidenced through a management system aligned with recognised standards – is factored positively into the risk assessment.
