An explosive device includes a firing train, an explosive charge and a shock activated neutralizer configured to disable activation of the explosive charge by the firing train. The neutralizer includes a housing and a rupturable fluid barrier configured to selectively permit mixing of disabling material constituents to interact with the firing train to disable the same. A method of neutralizing an explosive device includes rupturing the fluid barrier, at least in part by applying a shock to the explosive device, and interacting the disabling material with the firing train to disable the same.
