Chemical Plants – Risk Profile and Loss Prevention

Hazard profile

Chemical plants frequently process flammable liquids and gases, reactive substances and toxic or environmentally hazardous materials at the same time. This creates a hazard profile in which fire, explosion and release scenarios can reinforce one another: a pipe leak can trigger a vapour cloud explosion whose pressure wave in turn damages vessels containing further hazardous substances. Piping and vessel integrity, static electricity and uncontrolled chemical reactions are among the most frequent causes of major losses in the sector.

Protection measures

Industry-typical protection measures include classification of hazardous areas, redundant safety, alarm and interlock systems for critical process parameters, emergency relief and containment systems for upset conditions, and systematic maintenance of asset integrity. These technical measures are only effective in combination with structured process safety management, which governs hazard analysis, management of change and operating procedures across the entire plant lifecycle.

Insurance relevance

Chemical plants rank among the property risks with the highest possible loss severity, since a single event can simultaneously cause property, business interruption and environmental damage. In Switzerland and the EU, larger installations are additionally subject to major-accident legislation, and insurers regularly use the resulting safety reports as a basis for risk assessment.
