It can just be alarmed after life, or when being burned to certain degree, this is very unfavorable to control fire.It is best for fire
Fire-fighting method be to scent a hidden danger in time, prevent from leading to fire, that is, fire alarm carried out, especially for as train
Vehicle, can be to potential dangerous progress early warning if before fire generation, it will reduce many unnecessary losses.Train fire
Calamity is broadly divided into the combustible fire that appliance fire and passenger carry, and the fire of such as electric equipment is due to that electric current is different mostly
The insulant that often excessive temperature rising is caused is on fire, but before on fire, with the rise of temperature, these insulators can be distributed
Substantial amounts of pyrolysis particle, the polyvinyl chloride of such as electric wire（PVC）Insulation sheath and the insulating sheath for protecting electrical equipment（ABS materials）
Can distribute pyrolysis particle after heated, just as the smell of burning smelt sometimes in life, appearance of this pyrolysis particle in compartment or
Unusual fluctuations imply that the danger that burning occurs；Other fire is sometimes what the combustible that passenger's violation band gets on the bus was caused, especially
It is some volatile fuel gas, such as oil, alcohol, when these materials are just on fire, insufficient due to burning, burning can be distributed
Go out substantial amounts of CO etc. for clean-burning gas, this gas is not only poisonous, be also the signal that burning occurs, it is possible to use this
Feature timely carries out early warning to the burning just occurred.
Because the water that train is carried is less, if put out a fire when fire occurs using the mode watered, it can waste a large amount of
Water；Density of personnel also in railway car is larger, and severe contamination compartment article and passenger are understood with common foam annihilator,
