The device has a container (10) containing an aqueous solution and integrated with an envelope (12) that is divided into a housing (24) for storing a chemical compound e.g. calcium, and a housing (25) enclosing a voltage triggering circuit (11). A cap (23) is placed between the housing (24) and the container for constituting a total sealing between the compound and the solution by an absence of triggering order of the circuit. An actuator is controlled by the circuit for exploding the cap after a predetermined time-out to cause the chemical reaction inside the container. |
