Abstract: The present invention is a device to suppress or extinguish fires. In some embodiments, the fire extinguisher of the present invention comprises a fire extinguishing agent, a housing comprising a first material for retaining the fire extinguishing agent, and an attachment means for attaching the fire extinguisher to a surface. The fire extinguisher is actuated when the first material loses integrity upon exposure to a predetermined high temperature or exposure to open flames, resulting in a release of the fire extinguishing agent on the target area and thereby suppressing the fire or potential fire.
