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 suppression system has a fire suppression apparatus configured to be installed in a target object targeted for fire protection. The apparatus has a storage space containing fire suppression agent. A remote device is configured to wirelessly communicate with the apparatus. A first sensor is configured to measure the storage space pressure and to send a wireless signal to the remote device representing the measured pressure. Another feature of the target object is configured to wirelessly communicate with the remote device and the other feature is not targeted for fire protection. The other feature includes a second sensor configured to measure a characteristic of the other feature and to send a wireless signal to the remote device representing the measured characteristic. The fire suppression apparatus may resemble a traditional fire extinguisher or may have a storage vessel with an outer wall containing the suppression agent. The outer wall may be configured to rupture when exposed to a fire to discharge the agent.

A fire suppression system may include a tank and a manifold that may be inside or outside the tank. The tank, when charged, holds a liquid and a gas. The manifold has an inlet coupled to receive a liquid flow from the tank and inlets configured to receive gas flows. The gas flows may be from an upper portion of the liquid tank. An expansion chamber in the manifold receives the liquid flow and the gas flows, which create a liquid-gas vortex or circulation around the expansion chamber that produces foam.

In a system for measuring a fire suppressant or fire suppression propellant quantity, the system comprising: a base (102); a top plate (106) positioned to support a tank (22) of said fire suppressant or fire suppression propellant; a plurality of springs (112) positioned between the top plate and the base to support the top plate atop the base, the plurality of springs positioned to support the top plate along a range of motion between an extended condition and a retracted condition; a first magnetic member (142) mounted to the base; a second magnetic member (140) mounted to the top plate so that a spacing between the first magnetic member and the second magnetic member decreases as the top plate moves from the extended condition to the retracted condition. At least one of the first magnetic member and the second magnetic member is a permanent magnet. A magnetic field sensor (160) is positioned to detect changes in a magnetic field associated with changes in said spacing.

A sterilization system includes a sterilization chamber, a processor, and a sterilization module. The sterilization module includes a frame assembly, an extraction assembly, and a carriage assembly. The extraction assembly is configured to extract a sterilant fluid from a cartridge and transfer the sterilant fluid to the sterilization chamber. The carriage assembly includes a motor, a carriage body, and a translating flag. The carriage body is configured to receive the cartridge. The translating flag is configured to move from a first position to a second position relative to the carriage body in response to the carriage body receiving the cartridge. The sensor is configured to detect movement of the translating flag from the first position to the second position.
