An initiator assembly that includes an initiator and a containment shell. The initiator has an initiator housing, an initiator device mounted inside the initiator housing, and an input charge that is formed of an energetic material. The initiator device is configured to initiate at least one of a combustion event, a deflagration event and a detonation event in the input charge. The containment shell is coupled to the initiator housing and defines a space into which gas and/or particles are ejected from the initiator housing if the initiator device is not activated and the input charge is cooked off.

1. An initiator assembly comprising: an initiator having an initiator housing, an initiator device mounted inside the initiator housing, and an input charge that is formed of an energetic material, the initiator device being configured to initiate a detonation event in the input charge; anda containment shell coupled to the initiator housing, the containment shell defining a space into which gas and/or particles are ejected from the initiator housing if the initiator device is not activated and the input charge is cooked off, the containment shell being configured such that the gas and/or the fragments produced when the input charge is cooked off is/are contained substantially permanently within the initiator assembly. 2. The initiator assembly of claim 1, wherein the initiator comprises a plurality of first terminals, which are electrically coupled to the initiator device and extend through the initiator housing. 3. The initiator assembly of claim 2, further comprising a plurality of second terminals that extend through the containment shell, the second terminals being electrically coupled to the first terminals. 4. The initiator assembly of claim 3, wherein the second terminals are sealed to the containment shell. 5. The initiator assembly of claim 3, wherein a flex circuit couples the first terminals to second terminals. 6. The initiator assembly of claim 1, wherein the containment shell and the initiator housing are integrally formed. 7. The initiator assembly of claim 1, wherein the containment shell comprises an inflatable bladder. 8. The initiator assembly of claim 1, wherein a portion of the initiator housing is threaded. 9. The initiator assembly of claim 1, wherein the initiator housing and the containment shell couple to one another through a connector interface, the connector interface comprising a first connector portion and a second connector portion, the first connector portion being fixed to the initiator housing, the second connector portion being coupled to the containment shell, the second connector portion having a plurality of second terminals, which matingly engage the first terminals, and a plurality of vent apertures that couple at least one of the first connector portion and the initiator housing in fluid connection with the containment shell. 10. An initiator assembly comprising: an initiator having an initiator housing, an initiator device mounted inside the initiator housing, and an input charge that is formed of an energetic material, the initiator device being configured to initiate a detonation event in the input charge; anda containment shell coupled to the initiator housing, the containment shell defining a space into which gas and/or particles are ejected from the initiator housing if the initiator device is not activated and the input charge is cooked off, the space being sized such that the gas and/or the fragments produced when the input charge is cooked off is/are contained substantially permanently within the initiator assembly. 11. The initiator assembly of claim 10, wherein the space has a volume that is less than or equal to 15 cc but greater than or equal to 1 cc. 12. The initiator assembly of claim 11, wherein the volume of the space is less than or equal to 10 cc. 13. The initiator assembly of claim 12, wherein the volume of the space is less than or equal to 5 cc. 14. The initiator assembly of claim 10, wherein the initiator comprises a set of first terminals, and wherein the containment shell comprises a set of second terminals and a connector circuit, the set of first terminals extending through the initiator housing and being electrically coupled to the initiator device, the set of second terminals extending through the containment housing, the connector circuit coupling each of the second terminals to a corresponding one of the first terminals. 15. The initiator assembly of claim 14, wherein the connector circuit has an inductance of less than 250 nH when power that is configured to cause the initiator device to operate is transmitted through the connector circuit. 16. The initiator assembly of claim 15, wherein the inductance of the connector circuit is less than or equal to 50 nH. 17. The initiator assembly of claim 16, wherein the inductance of the connector circuit is less than or equal to 30 nH. 18. The initiator assembly of claim 14, wherein the connector circuit is a flex circuit. 19. The initiator assembly of claim 10, further comprising an insulator coupled to at least one surface that bounds the space. 20. The initiator assembly of claim 19, wherein the insulator comprises a shell that is mounted within the containment shell. 21. The initiator assembly of claim 19, wherein the insulator comprises an electrically insulating material that is mounted to a surface of the initiator.
