The present invention is a fire suppression apparatus for mitigating a battery fire and the effects of a thermal event within a battery pack. The system comprises a fire suppressant apparatus that is incorporated into the storage modules of the lithium ion batteries. Each storage module includes a container filled with a fire suppressant that is pressurized with a compressed gas.

An agitator for disposition within a cavity of a vessel body containing a particulate includes a weighted portion and a stirring portion. The agitator is positioned and disposed relative to the vessel body to move the stirring portion through the particulate in response to movement of the weighted portion in response to gravitational and/or inertial forces acting on the weighted portion due to movement of the vessel body. Particulate storage vessel arrangements and methods of particulate mixing are also described.

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.

The present invention is directed to a fire extinguisher having a built-in module for providing auditory instructions on how to use the fire extinguisher properly in an emergency situation. The present invention features a fire extinguisher comprising a chamber for holding extinguishing chemicals and a cap screwably attached to the chamber. The cap may comprise a release valve, a handle for activating the release valve, a safety pin for preventing activation of the handle before safety pin removal, a nozzle for directing extinguishing chemicals, and a pressure gauge. The fire extinguisher may further comprise an instructional module disposed in the cap for relaying audio instructions through a speaker. The speaker may be actuated by an activation mechanism disposed on the cap.
