Improvements to a portable fire extinguisher are disclosed. The improvements allow for frequent and simplified inspection and maintenance of a fire extinguisher with minimal training and without need for custom equipment. The improvements include an anti-bridging mechanism that can be articulated from the exterior of the chamber to fluff, mix or stir the powder within the chamber to keep it in a liquefied state. Additional improvements include a larger opening to more quickly fill and inspect the powder within the chamber. Another improvement includes the use of a CO.sub.2 cartridge located external to the chamber to allow easier servicing or replacement of just the CO.sub.2 cartridge as well as the ability to maintain the chamber in an un-pressurized condition, allows for non-HASMAT shipping. These features will extend the service intervals while maintaining the fire extinguisher in a ready condition.

A fire extinguisher is shown and described. The fire extinguisher may include a housing, a vessel positioned within the housing, the vessel retaining a fire suppression agent therein, and a discharge port positioned in the housing and operatively coupled with the vessel, where the fire suppression agent is capable of being expelled from the discharge port. The fire extinguisher may include an electrical connector positioned on the housing, the electrical connector capable of operatively securing to an electrical outlet, where the electrical connector is rotatable relative to the housing.

A method of actuating an extinguisher system may comprise retaining a broadhead cutter in close proximity to a burst disc surface, receiving an impulse signal, actuating a spring release mechanism in response to receiving the impulse signal, driving a cutter shaft towards the burst disc surface in response to actuation, and piercing the burst disc surface via the broadhead cutter coupled to the cutter shaft.
