Abstract

L'invention concerne un système d'extinction d'incendie (10) pour un espace sensiblement clos (12) présentant une source potentielle de ré-allumage de feu (14) à l'intérieur de celui-ci. Le système (10) comprend un ou plusieurs récipients (16) ayant une alimentation en un premier agent d'extinction d'incendie et une alimentation en un second agent d'extinction de feu, des conduits (22, 24) pour transporter les agents d'extinction d'incendie à partir du récipient ou des récipients (16) vers l'espace sensiblement clos (12), et un actionneur (32) utilisable pour amener les agents d'extinction d'incendie à être distribués à partir du ou de chaque conteneur (16) à l'espace clos (12). Le système (10) est utilisable pour délivrer des agents d'extinction d'incendie consécutivement et dans une succession rapide à l'espace clos (12). Le premier agent d'extinction d'incendie est utilisé pour éteindre un incendie à l'intérieur de l'espace clos (12), tandis que le second agent d'extinction d'incendie est utilisé pour refroidir l'espace clos (12) et empêcher ainsi le ré-allumage de l'incendie par la source de ré-allumage d'incendie (14).
