Its adaptive fire is the same as a portable chemical foam extinguisher.
Use: When used, generally by two people operation, the fire extinguisher quickly pushed to the fire, in the distance from the ignition point of 10 meters stop, by one person cast the hose, hold the lance with both hands and aim at the burner; the other first counterclockwise direction to turn the wheel, the screw rose to the highest position, so that the cap open, and then the cylinder back to the ground, so that the lever touch, and the valve handle rotation 90 degrees, you can spray foam to fire. If the valve is mounted at the spray gun, the valve is opened by the person responsible for the operation of the spray gun.
Fire extinguishing methods and precautions and portable chemical foam fire extinguishers are basically the same, can be referenced. Because the fire extinguisher's spraying distance, the continuous injection time is long, therefore may give full play to its superiority, uses in saves the large area the storage trough or the oil tanker and so on place the initial fire.
When using a trolley type fire extinguisher, turn the rear part toward the source of fire (the outdoor should be placed in the upper direction), first remove the spray gun, expand the powder tube (remember not to twist the phenomenon), and then lift into the air pressure bar, so that carbon dioxide into the tank, when the table pressure to 0.7 trillion PA ~ 1 MPa, put down into the air pressure bar to stop the air intake. Then turn on the switch, spray out dry powder, from near to far to fire. such as extinguishing oil fires, do not make the dry powder direct impact of oil stains, so as not to splash the surface of the fire spread.
