An inert seal explosion suppression device used for hazardous chemical container, and a defense method responding to multistage shaped charge that aims at conducting sympathetic detonation on oxygen-contained hydrocarbon gas in gas-phase space of the container in a mode of detonation inside the follow-through warhead container. The device comprises an inert seal device arranged on the hazardous chemical containers. The device comprises an U-shaped sleeve (3), a Y-shaped penetrating pipe is arranged inside the U-shaped sleeve, one upper port of the U-shaped sleeve is communicated with the gas-phase of a gas inert seal medium source, the other upper port of the U-shaped sleeve (3) is communicated with the container in gas-phase state through an inert seal disc on the top of the corresponding container, a port on the gas distribution side of the Y-shaped penetrating pipe is hung in a vertical pipe on the gas distribution side of the U-shaped sleeve, a side port of the container is connected with a spraying pipe on the top of the container, a bottom port communicated with a liquid-state fire protection medium source through a bottom connection pipe of the U-shaped sleeve, that can use a liquid valve of the sleeve as a large and small breath valve, and can use a liquid valve of the penetrating pipe as a safety relief valve, that can isolate systematically the atmosphere and restrain permanently the combustion explosion condition of the gas-phase space in the container and the pipelines.

A selectable force gas generator (SFGG) includes support material of honeycomb structure and a gas collection chamber contained in a housing. Gas-generating propellant cells are partially embedded in the support material. Each of the gas-generating propellant cells includes a steel jacket having a convex portion exposed to the gas collection chamber. The steel jacket has an orifice through the convex portion. Each propellant cell includes a propellant packet contained in the jacket. Each propellant cell includes a fire wire electrically connectable to an electrically-fired initiator and electrically connected to the propellant packet. The fire wire transmits a firing signal that causes the propellant packet to produce gas. A cap is positioned between the propellant packet and the jacket. The cap has a tip that blocks the orifice of the jacket and the thickness of the jacket is sufficient to prevent sympathetic detonation of the propellant packet.
