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.

The technology disclosed relates to a fire extinguisher, a monitoring system and methods for detecting leakage and/or determining whether leakage from the cylinder of a fire extinguisher has occurred. In particular, the technology disclosed relates to a fire extinguisher, a monitoring system and methods for determining whether leakage from the cylinder of a fire extinguisher has occurred by compensating for how the rate of surrounding temperature variations affects weight measurement readings obtained from a load cell of the fire extinguisher. In embodiments, the technology disclosed relates to a fire extinguisher, a monitoring system and methods for filtering weight measurement data obtained from a load cell of a fire extinguisher.

Device for delivering gases for extinguishing fire in an enclosed space. The device comes in a spherical shape, the top and bottom of which respectively have an entry hatch. Each entry hatch is held in place by four keyed cam locks. The device includes spiral bevel gears, a stationary ring and four pinions. Each pinion is responsible for containing/releasing the gases stored therein. Each pinion connects to a cylinder that connects to a cone having slits that allow the gasses to travel in different directions. The device is pitched from outside into the enclosed space or burning room. The device allows first responders with either a timed extension to rescue trapped individuals/things or potentially extinguish a burning room. The device withstands structure fires without becoming damaged. The gases contained inside the device are safe to use in areas populated by humans and are both effective and safe for inhalation.
