The fire extinguisher includes a container filled with a fire extinguishing liquid and having a normally closed main outlet and support structure extending through an opening of the container wall. A compressed gas cartridge located in the container is supported by the support structure. The support structure has an opening formed therethrough which leads to the end of the compressed gas cartridge. A plunger, an explosive charge, and a heat sensitive fuse, the latter of which has a portion is exposed to the exterior of the container, are located in the opening of the support structure. In the presence of high temperature, the fuse causes the explosive charge to explode and force the plunger to rupture the cartridge which release the gas into the liquid in the container by way of a normally closed gas outlet formed through the wall of the support structure. This causes the liquid to be forced out of the container by way of the normally closed main outlet. In another embodiment, the fire extinguishing material in the container may be a powder.
