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.

The present invention relates to a fire extinguishing system for a commercial kitchen. The fire extinguishing system comprises a canister containing a fire extinguishing agent and a gas expellant. In the event of a fire or conditions that pose a threat of a fire, the internal pressure in the canister is utilized to actuate a main control valve of the canister which releases the fire extinguishing agent from the canister.

A fire detection device and method therefor are able to provide automatic activation so as to extinguish a fire. The fire detection can be rapid and temperature-based. In one embodiment, a heat collector can be provided to enhance thermal responsiveness. Activation of the fire detection device can be electrically induced to release an extinguishing agent at the fire. The activation can be protected such that it is durable and unaffected by vibrations.

A system for storing a fire extinguishing agent is provided. The system comprises: a fire extinguishing tank configured to store fire extinguishing agent, the fire extinguishing tank having an orifice; and a valve located in the orifice configured to regulate pressure of the fire extinguishing agent exiting the fire extinguishing tank when the valve is opened; wherein the fire extinguishing agent comprises halocarbon.

Various embodiments disclosed relate to dry powder fire-fighting compositions. In various embodiments, the present invention provides a method of fighting a fire. The method can include contacting at least one of a fire and a source thereof with a composition including bentonite and aluminum hydroxide.

A fire suppression system includes a pipe having one or more dispersion features, a valve assembly coupled to the pipe, and a fire extinguisher unit coupled to the pipe via the valve assembly. The fire extinguisher unit includes a tank containing a fire suppressing agent. The valve assembly includes a connector with a first part attached to the fire extinguisher unit and a second part attached to the pipe. The valve assembly permits the fire extinguisher unit to be connected to the pipe of the fire suppression system to share the fire suppressing agent with the pipe and the one or more dispersion features to suppress fire or to be disconnected from the pipe for manual use to suppress fire.

A fire suppression apparatus (1000) comprises an enclosed hollow cylinder (1100) for containing a firefighting agent (not shown). The cylinder (1100) has a cylindrical side wall (1110) and upper and lower dome-ends (1120) and (1130), respectively. The lower end (1130) features supporting feet (1132). At the upper end (1120), an outlet valve (1122) is mounted on a neck-ring (1123) of the cylinder. The valve (1122) comprises an inlet connected to a dip-tube 1200 having a venturi device (1300). The valve itself comprises an outlet (1124). A nozzle, or distribution network to nozzle(s), (not shown) may be attached to threaded stub (1126) to direct firefighting agent during discharge.

A safety handle of a fire extinguisher includes a lower handle coupled to an upper end of a valve and having a first hinge shaft at one end thereof and a first support shaft parallel to the first hinge shaft at a point spaced from the first hinge shaft. An upper handle is coupled to the lower handle to be rotatable around the first hinge shaft and downwardly rotate around the first hinge shaft to push an open pin of the fire extinguisher. A second support shaft is parallel to the first hinge shaft at one point. A safety pin prevents the upper handle from rotating. A first link having a first end of a length direction is coupled to the first support shaft to be rotatable around the first support shaft. A second link having a first end of a length direction is coupled to the second support shaft.
