The Fire extinguisher spray is a single-use, aerosol pressurized container that generates, when discharged, a stable and lasting fine foam, which cover quickly the fire, hindering his contact from the atmospheric oxygen that maintains the burning.

The fluid resulted after the foam melting cools the surfaces, preventing reignition. The propeller agent is the nitrogen.

The Fire extinguisher spray is used in small, incipient class A (combustible solids) and B (combustible fluids) fires, in car fires (provoked by the electric installation, fuel), in household and camping (because of textiles, papers, wood, oils, solvents, braise, etc).
