A device is provided for rendering fuel inert in a fuel holding facility. Means such as a frangible seal are activated when a predetermined force is applied such as when a vehicle airbag is released. An inertial switch may be provided. This releases a chemical from a container in the facility. When the chemical is mixed with the fuel, it reduces the risk of explosion of the fuel which is for example petrol in a fuel tank of a car. The chemical may comprise one or more of polyurethane resin with toluene diisocyanate, maleic anhydride and ethylene glycol, AFFF, water, a Halon and monoammonium phosphate powder. The chemical may alter the state of the fuel to a more solid or gel like form or, alternatively, foam with the action of a polymerising agent or emulsifier/ detergent respectively. |
