Fixed firefighting systems - Foam systems - Part 2: Design, construction and maintenance

This European Standard specifies the requirements and describes the methods for design, installation, testing and maintenance of low, medium, and high expansion foam fire extinguishing systems.
This European Standard provides guidance for the design of various foam systems available to persons with knowledge and experience in determining the selection of foam fire extinguishing systems which will be effective in protecting specific hazard configurations. The requirement for foam systems derives from risk assessment by those competent to carry out such assessments which are outside the scope of this European Standard.
This European Standard does not cover a risk analysis carried out by a competent person.
Nothing in this European Standard is intended to restrict new technologies or alternative arrangements, provided that the level of safety prescribed in this standard is not lowered, and supported by documented evidence/test reports.
All foam systems are generally unsuitable for the following:
-   chemicals, such as cellulose nitrate, that release sufficient oxygen or other oxidising agents which can sustain combustion;
-   energized unenclosed electrical equipment;
-   metals such as sodium, potassium and sodium-potassium alloys which are reactive to water;
-   hazardous, water–reactive materials such as triethyl-aluminium and phosphorous pentoxide;
-   combustible metals such as aluminium and magnesium.

Ortsfeste Brandbekämpfungsanlagen - Schaumlöschanlagen - Teil 2: Planung, Einbau und Wartung

Diese Europäische Norm legt Anforderungen an die Planung, den Einbau, die Inbetriebnahme und den Betrieb von Schwer-, Mittel- oder Leichtschaumlöschanlagen fest.
Mit dieser Europäischen Norm wird Personen mit dem entsprechenden Kenntnisstand und Erfahrungen bei der Auswahl von Schaumlöschanlagen ein Leitfaden für die Planung verschiedener Schaumlöschanlagen zur Verfügung gestellt, mit denen ein effektiver Schutz bei speziellen Brandgefahren erzielt werden soll. Die Anforderung an Schaumlöschanlagen beruht auf den durch fachkundige Personen durchgeführten Risikobewertungen — die außerhalb des Anwendungsbereiches dieser Europäischen Norm liegen.
Diese Europäische Norm gilt nicht für Risikoanalysen, die von einer fachkundigen Person durchgeführt werden.
In dieser Europäischen Norm werden keinerlei Beschränkungen hinsichtlich neuer Technologien oder alternativer Lösungen vorgenommen, vorausgesetzt, das in dieser Norm beschriebene Sicherheitsniveau ist nicht niedriger und dies durch Prüfberichte nachgewiesen wird.
Alle Schaumlöschanlagen sind generell ungeeignet für:
-   Chemikalien wie Cellulosenitrat, die genügend Sauerstoff oder andere Oxidationsmittel freisetzen, die die Verbrennung unterstützen;
-   stromführende freiliegende elektrische Einrichtungen;
-   Metalle wie Natrium, Kalium und Natrium-Kalium-Legierungen, die mit Wasser reagieren;
-   gefährliche, mit Wasser reagierende Stoffe wie Triethylaluminium und Phosphorpentoxid;
-   brennbare Metalle wie Aluminium und Magnesium.

Installations fixes de lutte contre l’incendie - Systèmes à émulseurs - Partie 2 : Calcul, installation et maintenance

La présente Norme européenne spécifie les exigences et décrit les méthodes relatives au calcul, à l’installation, aux essais et à la maintenance de systèmes d’extinction à mousse bas, moyen et haut foisonnement.
La présente Norme européenne fournit des lignes directrices pour le calcul des différents systèmes à mousse, destinées à des personnes ayant suffisamment de connaissances et d’expérience pour sélectionner les systèmes d’extinction à mousse qui seront efficaces dans certaines configurations de risques spécifiques. La nécessité d’un système à mousse est définie par l’évaluation des risques réalisée par des personnes compétentes en la matière, ce qui n’entre pas dans le domaine d’application de la présente Norme européenne.
La présente Norme européenne ne concerne pas l’analyse des risques réalisée par une personne compétente.
Dans la présente Norme européenne, rien n’est destiné à limiter les nouvelles technologies ou les modifications possibles des installations, à condition que le niveau de sécurité prescrit par la présente norme ne soit pas minimisé, et qu’il soit justifié par des rapports d’essais/des preuves documentés.
Les systèmes à mousse ne sont généralement pas appropriés dans les cas suivants :
-   produits chimiques, tels que le nitrate de cellulose, qui libèrent de l’oxygène ou d’autres agents oxydants en quantité suffisante pour maintenir la combustion ;
-   équipements électriques non fermés sous tension ;
-   métaux tels que le sodium, le potassium et les alliages sodium-potassium qui sont réactifs à l’eau ;
-   matériaux réactifs à l’eau et dangereux tels que le triéthyl-aluminium et l’anhydride phosphorique ;
-   métaux combustibles tels que l’aluminium et le magnésium.

Introduction
Foam systems are designed to provide a homogeneous layer of bubbles, of aerated fire fighting foam concentrate
and water, over the surface of flammable liquids (Class B) and/or combustible materials (Class A). The layer of
bubbles will suppress the release of flammable vapours, exclude air, and cool the fuel and hot surfaces.
Applications for foam systems can be diverse so no one type of foam system can be prescribed. In addition, High
Expansion Foam may be used to provide total flooding of enclosures with 3 dimensional hazards of either Class
A and/or Class B fuels. Examples of the various types of foam system are set out in Table 1 below:

Warehouses – Class A and B fuels Yes No Yes
NOTE These examples are not prescriptive and do not preclude other uses, providing there is a fire engineering basis.
Foam systems reduce the environmental impact of fire by reducing fire effluent both into the atmosphere and
onto the ground. This is achieved through a more efficient application of fire extinguishing agent onto the seat of
fire. Compared to other extinguishing systems, the necessary application rate is significantly reduced by using
foam systems. Lower fire water damages and a reduced application of contaminated fire water in the
environment are also important advantages. Foam extinguishing systems give increased safety for the fire
fighting personnel and neighbouring communities.

1 Scope
This document specifies the requirements and describes the methods for design, installation, testing and
maintenance of low, medium, and high expansion foam fire extinguishing systems.
Foam systems may be used to suppress the release of toxic vapours but this application is outside the scope of
this document.
This document provides guidance for the design of various foam systems available to persons with knowledge
and experience in determining the selection of foam fire extinguishing systems which will be effective in
protecting specific hazard configurations. For the application of this standard, a risk assessment by a qualified
and experienced person should be performed for both new and existing systems, however the risk assessment
is outside the scope of this document.
This document does not cover a risk analysis carried out by a competent person.
Nothing in this document is intended to restrict new technologies or alternative arrangements, provided that the
level of foam system performance prescribed in this standard is not lowered, and supported by documented
evidence/test reports.
All foam systems are generally unsuitable for the following:
— chemicals, such as cellulose nitrate, that release sufficient oxygen or other oxidizing agents which can sustain
combustion;
— energized unenclosed electrical equipment;
— metals such as sodium, potassium and sodium-potassium alloys which are reactive to water;
— hazardous, water–reactive materials such as triethyl-aluminium and phosphorous pentoxide;
— combustible metals such as aluminium and magnesium.
