Fire Extinguishing System for Mobile Units

Despite the great progresses in the modern vehicle construction and in particular in their internal furnishing (nowadays realized only with materials able to delay the fire development and with low emission of smoke and toxic vapours), theoretical analysis and experimental tests have proven that in many situations the time required to stop in a proper place the train with the vehicle involved in the fire can widely exceed the time during which people in the vehicle can tolerate the inside conditions on the base only of the above described passive measures.

The variable represented by the fire load of passengers' clothes and (especially) luggage can assume very different values in the different operating conditions and, of course, decreases safety.
