Devices and methods for dispensing a fluidly dispensable material under pressure but without using a gas propellant are presented. In some embodiments an elastic sleeve is utilized to impart pressure to a bag of dispensable material positioned within the sleeve. Pressure so created pressurizes contents of the bag, which can then be dispensed through a valve. Methods for manufacturing various embodiments are presented.

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.

Fire extinguisher apparatus comprising at least one vessel containing a fire extinguishing medium and adapted to release said fire extinguishing medium when a fire or potential fire is identified characterised in that said fire extinguishing medium comprises an aqueous suspension of expanded vermiculite.

The present invention relates to an automatic fire extinguishing system for small spaces using fire extinguishing agents comprising the automatic fire extinguishing system to be installed in a small space, wherein the moving member is moved by an elastic body installed in the housing when the glass bulb installed in the housing is broken by heat from a fire; the fire extinguishing agents breaks the membrane of the tank storing the pressurized fire extinguishing agents with the striking member connected with the moving member; the striking member connected with the moving member breaks the membrane of the tank which stores pressurized fire extinguishing agents; and the pressurized fire extinguishing agents are spread to the small space, which leads to suppressing the fire at an early stage. When a fire breaks out in a small space susceptible for a fire such as distribution boxes, substation boxes, refrigerators, server racks, etc., the glass bulb installed inside the housing will be broken by heat; the moving member is moved by the elastic force of the elastic body; the striking member breaks the membrane blocking the opening of the tank; and the fire extinguishing agents pressurized in the tank are dispersed, which makes it easier to suppress a fire at an early stage.

Improvements to a portable fire extinguisher are disclosed. The improvements allow for frequent and simplified 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. These features will extend the service intervals while maintaining the fire extinguisher in a ready condition.

An apparatus may comprise: a vessel, a fire-suppression composition disposed within the vessel, wherein the fire-suppression composition comprises a fibrous clay mineral and a propellant gas; and a valve disposed on an outlet of the vessel wherein the valve has at least an open position with a flow path between an interior of the vessel and an exterior of the vessel and a closed position wherein the flow path is blocked.
