Portable type foam fire extinguisher and cart type foam fire extinguisher between what are the differences? Below we to adapt to the fire type and method of use on a comparison.

Portable type foam fire extinguisher adapt to fire and method of use

Applicable scope applies to save general class B fire, such as oil products, such as the oil fire, also can be applied to A kind of fire, but cannot save class B fire of water-soluble flammable, the fire of inflammable liquid, such as alcohol, ether and ester, ketone substances such as fire, Also cannot save charged equipment and C and D class fire. Fire extinguisher principle

Use method can be portable cylinder and the upper part of the lift ring, quickly to the fire. Then should pay attention shall not make fire extinguisher excessively lean, more do not cross take or reverse, lest two kinds of powders mixed early container. When the distance of ignition 10 meters, it will cylinder upside down, one hand clenched lift ring, another ahold of cylinder body bottom circle will jet alignment combustion. In saves flammable liquid fire, if already is flowing combustion, will bubble shape by far and near injection, make foam completely covered in burning liquid surface, As in containers should be burning, foam into container wall, make foam inner flow, gradually along covering fire liquid surface. Avoid by all means is pointed directly at liquid surface spray, lest because jet impact, but rather to burning liquid derided or rushed out of container, expand the scope of combustion. In fighting the fire solid material shall be jet alignment combustion most violent place. Extinguish with effective micro-injection distance shorten, users should gradually to burn area near, and always will be foam sprayed on combustion, until a fight. When using, fire extinguishers should always keep inverted state, otherwise you will interrupt injection. Foam fire extinguisher deposit should choose dry and ventilated and take with convenient place, not near the high temperature or may be insolate place, in order to prevent the carbonic acid decomposition and failure, Winter should adopt anti-freeze measures to prevent freezing, And often should erase dust, dredge nozzle and keep unobstructed.

Cart type foam fire extinguisher adapt to fire and using method

The adaptive fire and portable chemical foam fire extinguisher identical. Method of use when using, generally by two operation, first will fire extinguisher to push and pull to fire, at a distance of 10 meters of ignition in stop, by one casting injection hose, clasped gun and alignment combustion place, Another is first counterclockwise rotation handwheel, will screw liters to its highest position, make caps shattered, then cylinder backward dump, make bars, and will touch the valve handles rotates 90 degrees, can spraying foam extinguishing. If the valve installed in gun place, it is responsible for operating gun unpack valve. Extinguishing method and the matters needing attention and portable chemical foam fire extinguisher basic same, can consult. Because the fire extinguisher jet distance, continuous injection time long, thus can give full play to its advantages for saving larger area of the tank or the place such as the beginning of the tanker fires.
