Abstract
Improvements to a portable fire extinguisher where the improvements relate to a system where the owner of the extinguisher can service and maintain their fire protection. Systems in place today require the servicing of a third party. The service companies (third parties) are charged with maintaining the system. Further Improvements include an anti-bridging mechanism that is articulated from the exterior of the chamber to fluff, mix or stir the powder within the chamber to keep it in a liquefied state. The improvements further include a wall mounting bracket that reduces tampering with the extinguisher, an automatic fluffing motor and manual fluffing wheel with a chuck for use with a drill. These features extend the service intervals while maintaining the fire extinguisher in a ready condition. The fire extinguisher is construction of components that are interchangeable and provide equal operation for left and right handed people.
