A method for expelling a fire suppressant in a liquid phase from a container into a distribution manifold, the method comprising: generating a propellant gas that flows into the container via a first port of the container, thereby causing a pressure within the container to increase, wherein the container includes the fire suppressant in the liquid phase prior to the generation of the propellant gas; and in response to the pressure within the container exceeding a threshold pressure, expelling the fire suppressant from a second port of the container into the distribution manifold, wherein the generated propellant gas continues to flow into the container via the first port at least until substantially all of the fire suppressant included within the container prior to the generation of the propellant gas is expelled from the container via the second port, wherein generating the propellant gas comprises generating the propellant gas via a gas generator initiating a chemical reaction of one or more solid precursors of the propellant gas, wherein expelling the fire suppressant from the second port of the container into the distribution manifold comprises rupturing a rupture disc, that seals the second port, in response to the increased pressure within the container exceeding the threshold pressure, and after rupturing the rupture disc, causing the pressure within the container to remain greater than or equal to the threshold pressure at least until substantially all of the fire suppressant included within the container prior to the generation of the propellant gas is expelled from the container. generating a propellant gas that flows into the container via a first port of the container, thereby causing a pressure within the container to increase, wherein the container includes the fire suppressant in the liquid phase prior to the generation of the propellant gas; and in response to the pressure within the container exceeding a threshold pressure, expelling the fire suppressant from a second port of the container into the distribution manifold, wherein the generated propellant gas continues to flow into the container via the first port at least until substantially all of the fire suppressant included within the container prior to the generation of the propellant gas is expelled from the container via the second port, wherein generating the propellant gas comprises generating the propellant gas via a gas generator initiating a chemical reaction of one or more solid precursors of the propellant gas, wherein expelling the fire suppressant from the second port of the container into the distribution manifold comprises rupturing a rupture disc, that seals the second port, in response to the increased pressure within the container exceeding the threshold pressure, and after rupturing the rupture disc, causing the pressure within the container to remain greater than or equal to the threshold pressure at least until substantially all of the fire suppressant included within the container prior to the generation of the propellant gas is expelled from the container. wherein generating the propellant gas comprises generating the propellant gas via a gas generator initiating a chemical reaction of one or more solid precursors of the propellant gas, wherein expelling the fire suppressant from the second port of the container into the distribution manifold comprises rupturing a rupture disc, that seals the second port, in response to the increased pressure within the container exceeding the threshold pressure, and after rupturing the rupture disc, causing the pressure within the container to remain greater than or equal to the threshold pressure at least until substantially all of the fire suppressant included within the container prior to the generation of the propellant gas is expelled from the container.
