Abstract

La présente invention concerne une lance à incendie d'origine électrique (10) destinée à éteindre des objets en feu et qui présente un segment de maintien muni d'une poignée (11) destinée à un opérateur, une conduite d'alimentation en agent extincteur munie d'un dispositif d'accouplement (12) pour se raccorder à un tuyau sous pression pour agent extincteur liquide, ainsi qu'un segment extincteur tubulaire (13) se raccordant au segment de maintien et, le cas échéant, au dispositif d'accouplement, à l'extrémité libre duquel il est possible d'appliquer un agent extincteur sous pression dans un objet en feu. La poignée est électriquement isolée pour des tensions électriques U > 100 V et le segment extincteur est effilé avec une coupe transversale d'écoulement rétrécie destinée à l'agent extincteur envoyé à travers. La lance est caractérisée en ce que la poignée est également électriquement isolée pour des tensions électriques U ≥ 500 V et en ce que le segment extincteur est fabriqué à partir d'un matériau qui présente une résistance à la rupture Rm si élevée qu'il supporte une tension mécanique σ ≥ 500 N/mm2 et qui présente une température de fusion ts ≥ 650 °C, et en ce qu'un segment de maintien à l'extrémité côté opérateur présente une large plaque de frappe (14) dans le prolongement du segment extincteur. Ladite lance à incendie d'origine électrique répond de manière sûre aux exigences minimales aussi bien en matière de protection contre les risques thermiques qu'en matière de protection contre les surcharges mécaniques, et aussi en matière de risques électriques.
