      "body": "## Foam Types and Systems\n\nDepending on expansion ratio, foam is classified as low-, medium- or high-expansion. Foam-water sprinkler and foam-water spray systems combine the extinguishing action of water and foam in a single installation, while foam monitors and cannons enable large-area application, particularly in tank farms and aircraft hangars.\n\n## Agents and Environmental Considerations\n\nThe choice of foam concentrate depends on compatibility with the commodity being protected; regulatory restrictions on PFAS-containing compounds are currently accelerating the shift toward fluorine-free foams. Storage, shelf life and replenishment of the concentrate are recurring inspection points for any foam system.\n\n## Insurance Relevance\n\nFoam systems are the standard protection for liquid and tank storage with a high fire-spread potential. Insufficient concentrate stock, degraded old stock or incorrectly set proportioners are among the most common reasons foam systems fail to perform as designed in an actual loss event."

      "body": "## Schaumarten und Systeme\n\nJe nach Ausdehnungsgrad unterscheidet man Schwer-, Mittel- und Leichtschaum. Schaum-Wasser-Sprinkler und Schaum-Wasser-Sprühsysteme kombinieren die Löschwirkung von Wasser und Schaum in einer Anlage, während Schaummonitore und -kanonen vor allem in Tanklagern und Flugzeughangars grossflächige Löscheinsätze ermöglichen.\n\n## Löschmittel und Umweltaspekte\n\nDie Wahl des Schaummittels richtet sich nach der Kompatibilität mit dem zu schützenden Brandgut; regulatorische Vorgaben zu PFAS-haltigen Verbindungen beschleunigen aktuell die Umstellung auf fluorfreie Schaummittel. Lagerung, Haltbarkeit und Nachfüllung der Konzentrate sind wiederkehrende Prüfpunkte der Anlage.\n\n## Versicherungsrelevanz\n\nSchaumlöschanlagen sind Standardschutz für Flüssigkeits- und Tanklager mit hohem Ausbreitungsrisiko. Unzureichende Schaummittelvorräte, überalterte Konzentrate oder falsch eingestellte Proportionierer zählen zu den häufigsten Ursachen für eine ausbleibende Löschwirkung im tatsächlichen Schadenfall."
