Special Hazard Fire Protection Concepts
Special hazard fire protection concepts combine the selection and arrangement of extinguishing systems for hazards that cannot be reliably controlled by standard sprinkler protection alone, such as highly reactive materials, high-value equipment or specific process risks.
Selection Criteria
The fire behaviour of the hazard being protected, potential consequential damage from the extinguishing agent itself – such as water, foam, gas or dry chemical – along with the required response time and available detection options, all shape the choice of an appropriate extinguishing concept. Available space and structural integration further narrow the realistic options.
Typical Applications
Classic special hazards include turbine enclosures and transformers, paint spray booths, chemical plants, server rooms and archives, as well as process facilities with additional risks such as spark generation or dust explosion. Each of these cases requires extinguishing technology specifically matched to the hazard, going beyond standard sprinkler protection.
Insurance Relevance
Because special hazards often involve very high individual values or significant business interruption potential, risk engineers scrutinise the selected extinguishing system particularly closely to confirm it is genuinely approved and correctly sized for the specific hazard, rather than applying a standard concept unreflectively to an atypical risk.
