QUE SIGNIFIE FLASHOVER EN ANGLAIS
Flashover
Un flashover est l'allumage presque simultané de la plupart des matériaux combustibles directement exposés dans une zone fermée. Lorsque certains matériaux organiques sont chauffés, ils subissent une décomposition thermique et libèrent des gaz inflammables. Flashover se produit lorsque la majorité des surfaces exposées dans un espace sont chauffées à leur température d'auto-inflammation et émettent des gaz inflammables. Flashover se produit normalement à 500 ° C ou 1 100 ° F pour les combustibles ordinaires, et un flux de chaleur incident au niveau du sol de 1,8 Btu / pi² * s. Un exemple de flashover est quand un meuble est allumé dans une pièce domestique. L'incendie impliquant le mobilier initial peut produire une couche de fumée chaude qui se répand dans le plafond dans la pièce. La couche de fumée à chaud chaud augmente en profondeur, car elle est délimitée par les murs de la pièce. La chaleur rayonnée de cette couche chauffe les surfaces des matériaux combustibles directement exposés dans la pièce, ce qui provoque l'émission de gaz inflammables par pyrolyse. Lorsque les températures des gaz évolués deviennent suffisamment élevées, ces gaz s'allumeront tout au long de leur étendue.
définition de flashover dans le dictionnaire anglais
