A cartridge-operated fire extinguisher comprising a gas cartridge 124 for storing pressurised fluid 126 therein, and a spear 150 moveable from an initial first position in a first direction to pierce the gas cartridge 124, and moveable in a second direction to a second position to thereby indicate that pressurised fluid 126 has been released from the gas cartridge 124.

A fire suppression apparatus is configured to spray a fire suppressant agent and includes a reservoir and a nozzle. The nozzle is fluidly coupled to the reservoir and includes an inlet aperture, an outlet aperture, a passageway, and a diverter. The passageway extends between the inlet aperture and the outlet aperture. The diverter is disposed within the passageway and includes multiple diverter passageways configured to receive the fire suppressant agent from an inner volume of the diverter and direct the fire suppressant agent towards an inner sidewall of the passageway.

A method of manufacturing a self-expanding fire-fighting foam solution is disclosed. Here, the method can include purging air from a container, wherein the purging is performed via flowing an inert gas into the container, such that substantially inert environment is created within the container. In addition, the method can further include dispensing or filling a pre-determined amount of foam concentrate into a container, dispensing or filling a pre-determined amount of water into the container, and mixing the foam concentrate and water within the container, wherein the mixed foam and water within the inert container provide the self-expanding fire-fighting foam solution and having a pH ranging from about 6.8 to 7.8 moles per liter.

A fire extinguisher includes a body defining a storage chamber containing an extinguishing agent, a gas generator configured to pressurize the extinguishing agent in order to dispense it outside the body through an exit opening. The exit opening is equipped with a misting nozzle, and the extinguishing agent has a solidification temperature less than −10° C., the saturating vapor concentration of the extinguishing agent taken at −10° C. and at 1 bar being less than the extinguishing concentration of the extinguishing agent determined according to the ISO 14520 standard for a heptane fire at 1 bar.

A fire suppression system having a first triggering mechanism capable of being remotely triggered in response to a fire condition and a second manual triggering mechanism. More particularly, the fire extinguisher includes a valve for a fire extinguisher capable of manual and automatic operation. The system further includes a mechanism to notify of inoperable local status. During automatic operation, the system can be being triggered by a control panel in electrical communication, such as in response to a signal from smoke detectors. This system may also be manually triggered or in response to a temperature threshold sensor or other sensors. The valve includes an actuator that provides a separate area to place a safety pin for storing securely, and which provides feedback to the control system that the safety pin is properly stored and therefore, the fire extinguisher is active.

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.
