Abstract
A ballistically-safe wellbore tool may include an explosive device, an initiator including an initiating charge, and a bias member. A relative configuration of the explosive device and the initiator may be switchable between a first configuration, in which the initiating charge is at a ballistically safe distance from the explosive device, and a second configuration, in which the initiating charge is within a ballistically operable distance from the explosive device. The bias member is configured to bias the explosive device and the initiator to the first configuration.
