Selective control methods are provided for explosive systems which involve the placement of agents which act by dilution, physical or chemical means to alter the sensitivity of explosive (including pyrotechnic) materials or devices wherein: (1) the release may occur by the melting of the agent, rupture of a container or by pumping; (2) the agent is confined as a solid, is within a container capsule, is physically placed or mixed within the explosive as small or large pieces, is coated or molded on the walls or other parts of the device, or is held in an inactive position outside the action zone but is so arranged that it will be effectively placed on receipt of signal; (3) the signal to deactivate or activate may be heat supplied by the environment, or from an activating unit incorporated in the system, or pressure, or mechanical activation, wherein the signal may be the result of a command or set, or the output of a transducer control system.
